Walks Through the Flora of Newcastle – Walker Riverside

This circular walk of 3.3 miles takes around 3 hours at the height of summer when most of the interesting plants are in bloom. Meandering through several diverse, if somewhat unsightly, urban habitats, it provides a fantastic introduction to the flora of Tyneside’s brownfield and former industrial plots.

Rather unceremoniously, the route begins on Glasshouse Street (occurs.tubes.goat) outside of the Newcastle Resource Recovery Centre or tip, to use more familiar terminology. Here, you may care to explore the closely-sheered verge for Field Madder (Sherardia arvensis), Blue Fleabane (Erigeron acris) and Small-flowered Crane’s-bill (Geranium pusilum) but otherwise, head East for approximately 100m along the Hadrian’s Wall path taking care to note the variety of naturalised alien shrubs present here. Several have gone on to run amuck since their introduction in decades past.

Here, you’ll note Franchet’s Cotoneaster (Cotoneaster franchetii), Late Cotoneaster (Cotoneaster lacteus), Diel’s Cotoneaster (Cotoneaster dielsianus) and Darwin’s Barberry (Berberis darwinii), all of which are well at home along the scrubby bridleway. Before long, you’ll notice a well-trodden throughfare to your right, from which you will emerge intro a small car park on St. Lawrence Road. Seldom sprayed with herbicides, this carpark holds a notable mix of Alexanders (Smyrnium olusatrum), Viper’s-bugloss (Echium vulgare) and Common Toadflax (Linaria vulgaris). Of these, the former is notable as a relatively rare species within the city limits.

From here, cross the road to Dobson’s Crescent, following the road until you reach St. Peter’s Marina. About halfway down, you will notice yet another carpark dedicated in part to the storage of defunct boats. This unassuming patch of land is worthy of investigation as it is one of the few places you can note all three of the conurbation’s small-flowered fleabane species growing side-by-side. With ease, you should encounter Canadian Fleabane (Erigeron canadensis), Gurnsey Fleabane (Erigeron sumatrensis) and our native Blue Fleabane (Erigeron acris), alongside Narrow-leaved Ragwort (Senecio inaequidens), Atlas Poppy (Papaver atlanticum) and several other colonists.

At the marina, hug the banks of the Tyne and head East, over a wooden bridge along Hadrian’s Way. Of note here are Squirreltail Fecue (Vulpia bromoides), Water Bent (Polypogon viridis) and Glabrous Whitlowgrass (Erophila glabrescens) in paved areas, often alongside Greater Quaking-grass (Briza maxima) and Rock Crane’s-bill (Geranium macrorrhizum) that frequently escape nearby gardens.

Passing the final house on Hadrian’s Way, you will arrive on a narrow riverside path with dense scrub to your left and riverbank and eventually, the Tyne, to your right. From this point, you’ll enjoy a slow walk of approximately 0.7 miles towards Walker Riverside Park. The scrub is an interesting mix of native colonists and established relics. Of the latter, four are hard to miss with Persian Ivy (Hedera colchica), Many-flowered Rose (Rosa multiflora) and Himalayan Clematis (Clematis montana) dominant over their respective areas. The fourth, Wilson’s Honeysuckle (Lonicera nitida), is present throughout and is quickly becoming a pest. Somewhat harder to spot is the White-stemmed Bramble (Rubus cockburnianus) that persists in places.

Do not spend all your time gazing inland, however, as the tracksides and riverbanks along this stretch of the walk hold much of interest. Black Horehound (Ballota nigra), Wild Parsnip (Pastinaca sativa subsp. sylvestris) and Perennial Wall-rocket (Diplotaxis tenuifolia) are particularly prevalent along the path sides and amid the rubble strewn riverbank you’ll note plenty of naturalised Italian Alder (Alnus cordata) and coastal species such as Sea-aster (Tripolium pannonicum). But more on those seaside plants soon.

Two interesting plants that are much harder to see along this stretch are Black Spleenwort (Asplenium adiantum-nigrum), tucked away in the rubble heaps, and the hybrid horsetail, Equisetum x littorale, which can be found growing with Field Horsetail (Equisetum arvense) in select areas. Combing the riverside scrub should also produce Downy Birch (Betula pubescens) and much rarer, Spindle (Euonymus europaeus) while patches of Keeled Garlic (Allium carinatum) persist in places.

Hadrian’s Way will broaden when you reach the first of several parking bays frequented by local anglers – this marks the start of Walker Riverside Park, a sizeable area of restored brownfield managed by Urban Green Newcastle. The pavements at this point are delightfully messy and home to a great many interesting and, in some cases, rare ‘weeds’. Almost immediately, you will notice stands of Ribbed Melilot (Melilotus officinalis) and Tall Melilot (Melilotus altissimus), growing side-by-side for handy comparison; Hop Trefoil (Trifolium campestre), Great Lettuce (Lactuca virosa) and Common Mallow (Malva sylvestris).

Members of the dead-nettle family can be most diverse and in addition to the common species, one regularly finds Cut-leaved Dead-nettle (Lamium hybridum) and Henbit Dead-nettle (Lamium amplexicaule) growing amid the slabs. All of these can be noted as you continue Eastward along the Tyne; though do stop if you notice a blue flower atop the riverside wall. This will be Peached-leaved Bellflower (Campanula persicifolia) which has been established on-site for several years. 

 After around 100m (expect.stamp.plans) the path will narrow to such an extent to necessitate walking in single-file for a short distance. Along this stretch, the interesting weeds and alien shrubs continue with the addition of Red Valerian (Centranthus ruber), Willow-leaved Cotoneaster (Cotoneaster salicifolius) and Himalayan Cotoneaster (Cotoneaster simonsii). The real treat here, however, is a glimpse of the saltmarsh flora that would once have been far more widespread along the Tyne. Casting your eyes down the tidal defences you will note a clear transition from Sea-plantain (Plantago maritima) and Buck’s-horn Plantain (Plantago coronopus) in the upper reaches to Sea Aster (Tripolium pannonicum) in the splash zone and eventually Common Saltmarsh-grass (Puccinellia maritima) and the samphire lookalike, Purple Glasswort (Salicornia ramosissima) in the exposed mud. You can inspect all of these plants again on the remnants of St. Anthony’s Landing Stage further downstream (factor.reach.mice) so do not feel obliged to slide down the bank. At the stage, now well overtaken by nature, keep your eyes peeled too for Annual Sea-blite (Suaeda maritima), Hybrid Couch (Elymus x laxus) and Spear-leaved Orache (Atriplex prostrata).

After exploring the relic saltmarsh, continue Hadrian’s Way via a short flight of steps lined to each side by dense shrubbery, and plenty of established Wayfaring Tree (Viburnum lanata). Doing so, you’ll eventually emerge into an open area marked by bountiful grassland to left and again, the Tyne to your right. This is the site of the former St. Anthony’s Lead Works and is perhaps the most interesting portion of the walk.

The grassland, scrub and riverbanks here sit atop the former St. Anthony’s Quay are especially floriferous, though the origin of many species is uncertain. A seed mix was undoubtedly applied many years ago, and has introduced several curiosities, but ballast and natural colonisation may also have played a part. With ease, you will note copious Common Restharrow (Ononis repens), Wild Marjoram (Origanum vulgare), Musk-mallow (Malva moschata), Small Scabious (Scabiosa columbaria), Field Scabious (Knautia arvensis) and Chalk Knapweed (Centaurea debeauxii), all of which likely stem from strewn seed. With care, you should also pick out Lucerne (Medicago sativa subsp. sativa), Spiny Restharrow (Ononis spinosa), and Musk Thistle (Carduus nutans) while Wild Basil (Clinopodium vulgare) is increasingly common and Large-flowered Evening Primrose (Oenothera glazioviana) is a more recent colonist.

While it is possible to spend the entirely of your time along this stretch admiring the grassland, don’t – a look towards the river will not disappoint. The post-industrial banks here hold much of note including Hoary Mustard (Hirschfeldia incana), Traveller’s-joy (Clematis vitalba), Blue Fleabane (Erigeron acris), White Stonecrop (Sedum album) and Spreading Cotoneaster (Cotoneaster divaricatus). Perhaps most notable of all are healthy colonies of Flattened Meadow-grass (Poa compressa) which favours cracks and crevices in the stonework, and discrete patches of Keeled Garlic (Allium carinatum), presumably washed downstream from larger populations in Northumberland.

A final note here again centres on trees and shrubs and several of the species introduced in decades past have since gone on to seed or spread abundantly. Look out for Grey Alder (Alnus incana), False-acacia (Robinia pseudoacacia), Sea-buckthorn (Hippophae rhamnoides) and Japanese Rose (Rosa rugosa).

At this point, and you will begin the return leg of the trip. Doubling back along Hadrian’s Way you will notice a mud path (successes.shades.pretty) linking the riverside to an unexplored area up hill. Follow this and after around 40m, you will emerge into a clearing. This will instantaneously strike you as a demolition site and indeed it is with this small area of rubble and concrete representing all that remains of the lead works.  This is another highlight of the walk and holds many plants that are altogether rare in the wider conurbation. Some such as Small Scabious (Scabiosa columbaria) and Field Scabious (Knautia arvensis) may have spread from nearby seeded areas, but others are trickier to explain. On a good day in summer, you should observe the bell-shaped blooms of Clustered Bellflower (Campanula glomerata), spreading patches of Sainfoin (Onobrychis viciifolia), Quaking-grass (Briza media), Des Etang’s St. John’s-wort (Hypericum x desetangsii) and a healthy population of Yellow-wort (Blackstonia perfoliata). Wild Thyme (Thymus drucei) has also colonised areas of exposed stone and Kidney Vetch (Anthyllis vulneraria) is dominant across the whole area – a rare sight in these parts.

From this area, head West, passed some bollards intended to deter fly-tippers and out on to Pottery Bank. Attention should be paid to the small area of now rather rank grassland (yarn.hung.gladiators) immediately adjacent to the road which in past years has held both Bee Orchid (Ophrys apifera) and Pyramidal Orchid (Anacamptis pyramidalis). A little uphill, you will rejoin the Hadrian’s Wall Path which you will follow for roughly 1.5 miles back to St. Peter’s. Travelling back on this higher plane, you will find yourself surrounded by planted amenity woodland. While the canopy is uninspiring, the shrub layer is rather eclectic.

In addition to several of the cotoneasters mentioned previously, look out for Chinese Bramble (Rubus tricolor), Blue Holly (Ilex x meserveae), Box-leaved Honeysuckle (Lonicera pileata) and rampant Chenault’s Coralberry (Symphoricarpos x chenaultii). In places, ground cover is dominated by another introduction, Atlantic Ivy (Hedera hibernica) – though at least this is native – and do take heed of the small electricity substation (device.files.lifted). Here, you will encounter Newcastle’s only established population of Balkan Spurge (Euphorbia oblongata). Eventually, you will emerge by the tip where you began your journey.

Other interesting plants to look for along the way…

Fern-grass (Catapodium rigidum), Field Bindweed (Convolvulus arvensis), Swedish Cotoneaster (Cotoneaster x suecicus), Borrer’s Male-fern (Dryopteris borreri), Sheep’s-fescue (Festuca ovina), Meadow Crane’s-bill (Geranium pratense), Slender St. John’s-wort (Hypericum pulchrum), Wild Privet (Ligustrum vulgare), Hoary Ragwort (Jacobaea erucifolia), Salad Burnet (Poterium sanguisorba subsp. sanguisorba), Horse-radish (Armoracia rusticana), Green Field-speedwell (Veronica agrestis) and Hybrid Alder (Alnus x hybrida).

Exciting Botanical Discoveries in and Around Newcastle

Now that I’m over halfway through recording (and writing) an ‘Urban Flora’ for Newcastle and North Tyneside, you would think the surprises would have dried up somewhat. However, that does not seem to be the case. Despite visits to all monads across the conurbation and over 950 species recorded, new and exciting plants are turning up still. Whether they are entirely new species — sometimes for the city, sometimes for the county—or simply rare or unusual plants in new places, there has been much to enjoy in recent weeks. Here are a few recent highlights…

Rustyback (Asplenium ceterach)

Rustyback (Asplenium ceterach) is a Rare Plant Register species in VC67, meaning it is rare enough to warrant mentioning to a County Recorder whenever it is seen. Within the urban flora area, there is just one site for this species—an alleyway in Chirton—so I hadn’t expected to encounter it anywhere else. Imagine my surprise, then, when I stumbled across the rather lovely specimen pictured below (again in an alley) in Brunswick a few months back. Rumour has it that this fern is increasing in our region, so it will be interesting to see if it appears at yet more sites.

Snow-white Wood-rush (Luzula nivea)

Just over a month ago, Matt and I said out to explore Fordley Planta, a weird little community nature reserve located near Annitsford on the edge of the survey area. This turned out to be an interesting trip with local residents having guerrilla-planted several oddities in the otherwise unassuming little woodland. Few of these had spread beyond their initial position but one which had was Snow-white Wood-Rush (Luzula nivea), a plant native to the Alps and Pyrenees, seemingly well at home in North East England. In an hour’s exploration, we found several clumps of this attractive little plant. Dare it say that I prefer it to our native Great Wood-rush?

Galium x pomeranicum

This one is a little overdue with so much Hedge Bedstraw and Lady’s-bedstraw kicking about in Newcastle. Still, on a recent Natural History Society trip to Newcastle City Centre, I was pleased to encounter a nice example of this floriferous hybrid growing atop waste ground with both of its parents. Since then, it has turned up along Scotswood Road too where both of its parents have been introduced via an amenity seed mix.

Japanese Honeysuckle (Lonicera japonica)

For a short while now, a rampant honeysuckle overtaking a section of riverside scrub at Willington Gut, Wallsend, has been giving me sleepless nights. Knowing it was something ‘different’ but failing to catch it in flower (or fruit!) for two years straight, a few weeks back, I returned for another look. Thankfully, I caught the plant in bloom on this occasion and was able to confirm it as Japanese Honeysuckle (Lonicera japonica). This is a fairly frequent escapee in other parts of the country but until now, had not been reported at all in VC67. With several rather large plants present, it looked firmly established.

Common Wintergreen (Pyrola minor)

Far from common, for a few years now the only known population of this lovely little plant within the city was to be found at Gosforth Nature Reserve – I hadn’t expected to encounter it anywhere else. You can imagine my surprise then when during a trip to enjoy the displays of Dune Helleborine (Epipactis dunensis) at Newburn Riverside, I almost knelt on a patch while admiring the orchids. Once the site of the former Newburn Steelworks, this particular stretch of riverbank has developed a rather rich scrub community, likely atop soils heavily polluted with trace metals. Much of the site is due to be developed in the near future but I hope that this (and the helleborines) may avoid the bulldozers due to their positioning on the edge of the area.

Reversed Clover (Trifolium resupinatum)

Now this is an odd one. While exploring the town of Dudley a few weeks back, I opted to for a walk along the margins of some nearby arable fields where, among other unusual species such as Rye Brome (Bromus secalinus) I stumbled across the curious clover shown below. With a bit of digging, this was revealed to be Reversed Clover (Trifolium resupinatum), a grain or bird seed alien of Asian origin. How it got here is a bit of mystery though speaking with other botanists, it is likely to be been a crop contaminant.

Egyptian Clover (Trifolium alexandrinum)

An even more unusual find at Dudley came in the form of Egyptian Clover (Trifolium alexandrinum). Now, I confess, I hadn’t even heard of this one but again it looks to occur as a seed contaminant. However it got there, this marked the first record for South Northumberland.

Autumn Gentian (Gentianella amarella)

Something native now and while pottering about the site of the former Brenkley Colliery site near Dinnington, I was surprised to encounter a single Autumn Gentian (Gentianella amarella) growing beside a long neglected haulage track. This wouldn’t have been too noteworthy out in rural Northumberland where this species is uncommon but rather widespread, but in the city, it is an entirely different story. To date, this is the only record within the Newcastle city limits.

Lesser Water-parsnip (Berula erecta)

This has to be one of the highlights of the survey so far and a genuine surprise while walking a stretch of the Seaton Burn in the north of the conurbation. Lesser Water-parsnip (Berula erecta) is a terribly rare plant in South Northumberland and at one stage, was presumed locally extinct when its last known population at Ponteland died out. The population at Seaton Burn, spread out over 50m or so, is therefore rather notable and marks the first confirmed sighting of this riparian plant in a few decades, at least. Jampacked with other interesting aquatics, this stretch of river may turn up further noteworthy finds stills and represents some of the best wetland habitat to be seen locally.

Lesser Swine-cress (Lepidium didymum)

Despite it’s status as an abundant weed of damp and disturbed places in southern parts of the UK, Lesser Swine-cress (Lepidium didymum) is perplexingly scarce in the North East. So much so that it is another species featuring on the Rare Plant Register for South Northumberland. Perhaps this is truly the case or perhaps it is simply overlooked as either way, I have recorded it from three new sites in just two months. Firstly, from a flowerbed Kingston Park and later, from an abandoned car park at Arthur’s Hill. The final sighting, pictured below, came from disturbed ground in Jesmond Old Cemetery. I suspect it will turn up at further sites still.

Lawn Lobelia (Pratia angulata)

Concluding with what may be the most unexpected find of all and a few weeks back, a walk through an unassuming housing estate in Killingworth came up trumps with a sighting of Lawn Lobelia (Pratia angulata) unsurprisingly, growing out of a garden lawn. A rather attractive little flower, this species is native to New Zealand and is highly localised across the UK. How it came to reach the lawn in question is anyone’ could’s guess but either way, this marked the first known occurrence of this species in the vice-county. I’ve said it before, there is always something new to find in the city…

Speedwells (Veronica) in Newcastle and North Tyneside

In keeping with similar posts in this series exploring the plants uncovered during efforts to record the Urban Flora of Newcastle and North Tyneside, this week I wanted to take a look at a slightly more modest group of plants familiar from urban spaces nationwide: Speedwells.

So far, I have recorded 16 species of Veronica in Newcastle and North Tyneside, a much more manageable number than the 72 grasses covered here. With their cheerful blue flowers and propensity to bloom for most of the year in urban settings, Speedwells are a charming family and more so than many other plants encountered locally, are associated with highly anthropogenic habitats. Flowerbeds, roadworks, path sides, pavements, and other areas of disturbed ground, all are worth a look.

As always, a big thank you to the iRecorders who have made their photos available for use in articles such as this. In this case, Chris Barlow, Pru Hamed, and David Jarema.

Native Speedwells

Of the speedwells encountered so far in the conurbation, only eight are British natives. The rest are either neophytes—recent human introductions—or archaeophytes introduced many years ago. Of the native species, only a handful can be described as ‘common’ throughout the area.

Foremost among these abundant species is Wall Speedwell (Veronica arvensis), recorded from 42 (25.6%) of monads so far. An annual of disturbed and cultivated habitats, this species is most often encountered growing within the hard, free-draining surfaces of walls, pavements, and wasteground but is equally at home in neglected flowerbeds and on the margins of amenity grasslands. Anecdotally, it is more abundant in suburban neighborhoods where the spraying of weeds is less common.

The next two species, Germander Speedwell (Veronica chamaedrys) and Thyme-leaved Speedwell (Veronica serpyllifolia), are grassland plants. The former, recorded from 31 (18.9%) monads, is still greatly under-recorded but has defied expectations somewhat by proving scarcer than anticipated across the area. Typically, it is found either in good-quality neutral grassland, often that of road verges, or as a weed in garden lawns. However, it also occurs on the edges of amenity woodland and within urban hedgerows. Thyme-leaved Speedwell, recorded from 24 (14.6%) monads, inhabits much the same habitat but appears genuinely scarcer. It seems to favor long-established grasslands in churchyards and parks but may pop up in any suitable grassland area. It should be noted that all plants encountered so far are of the subspecies Serpyllifolia. I would not expect to see subsp. humifusa here, nor have I.

Similar in appearance to Germander Speedwell, at least at first, Wood Speedwell (Veronica montana) is a real rarity in the conurbation with fewer than 10 records since 1990. The majority of these are centered on Newcastle’s wooded denes at Jesmond, Throckley, and Walbottle, with a few records from other older woodlands. So far, this species has been recorded from 5 (3%) monads, all of which, except for a small patch at Heaton Park, come from these areas. Even where present, this plant is rather scarce and seldom forms the extensive colonies seen elsewhere in the county—a result of habitat degradation?

While a common plant of acidic soils elsewhere in the country, Heath Speedwell (Veronica officinalis) is likewise rare in Newcastle and its surrounds, recorded from 3 (1.8%) monads so far. Since 2000, there have only been eight records of this attractive little plant, predominantly from land close to Gosforth Park, much of which was once heathland. It is also present within relic lowland heath at Havannah Nature Reserve, though the greatest densities can be found within Gosforth Nature Reserve.

The final three native speedwells recorded so far are all plants of wetland habitats. Two are very scarce indeed, with Marsh Speedwell (Veronica scutellata) recorded from just 2 (1.2%) monads around established wetlands at Gosforth and Havannah, and Blue Water-speedwell (Veronica anagallis-aquatica) noted from just 1 (0.6%) monad at Gosforth Nature Reserve, where it grows on the muddy margins of recent SUDS.

Thankfully, Brooklime (Veronica beccabunga) is more abundant, recorded from 13 (7.9%) monads so far. This species can be encountered in a variety of wetland habitats ranging from the edges of lakes and ponds, SUDS, and streamsides to ditches and small wet depressions in built-up areas. It also appears to be one of the first riparian species to colonise new ponds, as seen at Kingston Park and Great Park.

Archaeophytes

Thus far, I have only encountered two archaeophyte speedwells during the survey, and both are rather common within urban habitats. Ivy-leaved Speedwell (Veronica hederifolia) is a prolific colonist of cultivated land, found just about anywhere the ground has been disturbed but most often as a weed of pavements, flowerbeds, wall bases, and allotment plots. Examples in urban habitats tend to be of subsp. hederifolia, which tolerates more open habitats than subsp. lucorum, which thus far has only convincingly been recorded from shaded woodland and parks. Together, these have been recorded from 61 (37.2%) monads.

Green Field-speedwell (Veronica agrestis), recorded from 28 (17.1%) monads, is much more abundant than it ought to be given its inclusion on the Rare Plant Register for South Northumberland. Indeed, despite only being recorded about ten times between 2000 and 2018, it is proving to be a frequent plant of disturbed habitats, though notably those with drier, freer-draining substrates than similar species. It may well warrant downgrading from the register in due course.

Alien Speedwells

Non-native speedwells now, and we’ll start with the simplest one: American Speedwell (Veronica peregrina), recorded from just 1 (0.6%) monad. A weed of cultivated and urbanised land, this attractive little plant was found growing in long-forgotten planters outside the Tyne Pedestrian Tunnel in North Tyneside. How long it has been there is unclear, but this seems to be a new population of what is, by all accounts, a rather rare neophyte locally.

Other alien speedwells are far more numerous. Take Common Field-speedwell (Veronica persica), for example, which genuinely seems to be the most abundant Veronica within the conurbation, recorded from 89 (54.3%) monads thus far. An annual of cultivated and disturbed soils, this species has an uncanny knack for popping up just about anywhere, from flowerbeds and pavements to arable fields and the margins of amenity grasslands. It will surely prove to be much more abundant still.

The same cannot be said for a similar species, Grey Field-speedwell (Veronica polita), which, while sharing the same habitats, appears altogether rare, recorded from just 4 (2.4%) monads to date. Past records of this species within the city are very scarce indeed, and befitting this, it has been recorded only scantly from a wall in Wallsend, a trodden path-side at Walker, and a few other locations.

Last but not least, we have Slender Speedwell (Veronica filiformis), recorded from 19 (11.6%) monads. Given its status as a successful weed of mown and amenity grassland, this one really ought to be more widespread, and I suspect it is significantly under-recorded due to my inability to access private gardens. Indeed, so far, it has predominantly been recorded from front lawns, churchyards, playing fields, and odd scraps of grassland left undeveloped within housing estates. Where present, it can be terribly abundant.

The final two Veronicas worthy of mention are not speedwells at all but Hebes. As they fall within the same family, they warrant inclusion here. Both Narrow-leaved Hebe (Veronica salicifolia) and Hedge Veronica (Veronica x franciscana) are rare escapes from cultivation in the conurbation, recorded from 3 (1.8%) and 2 (1.2%) monads, respectively. In the case of the former, where present, it appears to seed readily from older amenity plantings, while the latter seems to derive from planted garden hedges and is most commonly encountered within cracks in walls.

And there we have it, a round-up of the various speedwells encountered so far within Newcastle and North Tyneside. I have no doubt the numbers included here will change as the survey progresses, but at the very least, the results so far point to a few interesting trends.

The Urban Grasses of Newcastle and North Tyneside

While recording for the ‘Urban Flora‘ I have now come across a grand total of 72 grasses growing in a wild or naturalised state within the conurbation. This is roughly 7.5% of all species recorded in the survey area, and more still are being recorded by fellow recorders.

This is an incredibly diverse group and a real focus of the summer recording period. Now we’re a few years in and trends are finally beginning to emerge, I thought I’d share a [not so] brief round-up of the results so far in a similar manner to past posts here and here. Brace yourselves, this could turn out to be quite the essay…

Before I go any further, however, a very big thank you to Chris Barlow, who takes far better photos than I, for several of the images used within, and similarly to Pru Hamed and Joe Dobinson for their contributions made available through iRecord.

Common Grasses

The Big Seven

The ‘big seven’ urban grasses across the conurbation will come as no surprise to anyone. All are common and familiar species capable of thriving in a broad range of habitats. Few grasses demonstrate this better than Annual Meadow-grass (Poa annua) which has been recorded in 161 (98%) monads so far and gets just about everywhere – pavements, walls, garden lawns, quality grassland, you name it. Incidentally, this number corresponds to the total number of monads surveyed to date so it is likely that this species will eventually be recorded from all 164 squares.

Next up is Cock’s-foot (Dactylis glomerata) found in 149 (91%) monads so far. A robust grass characteristic of rank communities atop neutral or basic soils, it is the most frequent grass of roadside verges, urban wasteground and overgrown amenity grassland. I suspect this too will be recorded from all squares, as will the next two species, Red Fescue (Festuca rubra) and Perennial Rye-grass (Lolium perene), recorded from 110 (67%) monads each. Both are very widespread species of lawns and amenity grasslands, but occur too in more natural habitats, as well as in gardens, pavements and other urbanised environments.

Next, we have False Oat-grass (Arrhenatherum elatius) at 108 (66%) monads. Like Cock’s-foot, this species is a dominant fixture of rank neutral communities but anecdotally, occurs equally frequently as a weed of pavements and messy gardens. It will surely prove more widespread still.

Finally, we have Creeping Bent (Agrostis stolonifera) which while commonly encountered in its typical habitat of wetlands and around seasonal floods, also occurs as a frequent colonist of pavements, gutters and tracksides, and Yorkshire Fog (Holcus lanatus). Recorded from 72 (44%) monads thus far, the latter occurs just about anywhere but is most plentiful in damp situations and overgrown lawns.

Widespread Grasses

The next set of common grasses fall roughly into two broad habitats: quality grassland, typically atop neutral soils, and derelict and disturbed land. We will cover the former first but it should be noted that all of the grasses mentioned here are likely subject to under-recorded – there is still much more to do on this front, thus they are probably best described as ‘widespread’ as opposed to truly common.

Of the species I have come to associate with ‘quality’ grassland, Rough Meadow-grass (Poa trivialis) seems most abundant, found in 88 (54%) monads so far. This species is present in most natural grassland communities including those of roadside verges, parkland and field margins and those of neglected amenity grassland and seems absent only where management is most intense. Or perhaps it is simply undetectable when mown! The same can also be said for Meadow Foxtail (Alopecurus pratensis), recorded from 55 (33%) monads thus far, though both seem genuinely scarcer than the generalists featured higher up the list. The same habitats that feature the preceding two species also tend to hold Timothy (Phleum pratense), 43 (26%) monads, and Crested Dog’s-tail (Cynosurus cristatus), 31 (19%) monads; though both appear scarcer, both almost entirely absent from the most urbanised squares. Both appear linked to reseeding in some cases and more so than the previous two species, favour slightly ‘wilder’ grasslands.

Tufted Hair-grass (Deschampsia cespitosa) is also a frequent grass, recorded from some 55 (33%) monads. As a rule, it seems unphased by soil type and instead occurs wherever the land is poorly drained, most commonly in amenity and semi-natural woodland but also in ditches, damp grassland, and around urban ponds and SUDS where at times, it forms a unique community with several juncus species.

Finally in this very generalised category, we have Soft-brome (Bromus hordaceus) at 37 (22%) monads and Common Bent (Agrostis capillaris). The former occurs as isolated colonies just about anywhere there has been some degree of disturbance, typically favouring the edges of tracks, amenity grassland and rank verges where competition is limited. Recorded from 26 (16%) monads, the latter shows a strong preference for relic acidic habitats which are rather rare locally but may occur in neutral communities.

Derelict and Disturbed Land

The next set of frequent grasses are those associated with derelict land and disturbed habitats. Of these, two stand out as occurring most frequently in urban areas – Wall Barley (Hordeum murium), 41 (25%) monads, and Barren Brome (Anisantha sterilis), 42 (25%) monads. While they are not tied to it, these archaeophytes occur in areas of high disturbance including roadsides, pavements, wall bases and messy front gardens. Interestingly, both are more numerous in suburban areas such as Heaton, Jesmond and Gosforth but rather scarce in the city centre where efforts to control ‘weeds’ are more intense.

Common Couch (Elymus repens) is an interesting one in that it has only been recorded from 43 (26%) monads so far. An underestimation, for sure, though it does appear to be less frequent than perhaps I anticipated when starting out. Couch occurs scantly in the rank Cock’s-foot-False Oat-grass communities seen on verges but is more frequent on derelict land and brownfield sites. It seems to feature scantly in the lists shared by other local botanists too.

Water Bent (Polypodon viridis) is an interesting species. The story of this successful grass is well known but suffice to say that until recently, it was somewhat of a rarity in Tyneside. Recorded from 25 (15%) monads so far and increasing each year, this no longer seems to be the case. This grass is most numerous in Newcastle City Centre and the surrounding suburbs but as the survey progresses, is turning up in new locations towards the peripheries of the survey area. I suspect it will prove much more numerous when the majority of the area’s gutters and wall bases are thoroughly checked.

Localised Native Grasses

The vast majority of the grass species recorded so far in the conurbation can be described as uncommon or at the very least, somewhat localised. In many cases, this may be due to a lack of suitable habitat and genuine scarcity but in other cases, may be due to under-recording.

Woodland Species

The most abundant grasses of Newcastle and North Tyneside’s woodlands are undoubtedly the generalist species mentioned previously. Species such as Rough Meadow-grass and Tufted Hair-grass can be terribly common in such habitats, for example. There are, however, a rather select set of species that to date, have only been recorded from woodland settings.

Creeping Soft-grass (Holcus mollis) seems surprisingly picky, found in just 13 (8%) monads so far. This one appears tied to areas of amenity and semi-natural woodland, usually atop dry soils where competition is limited and at times, may form the dominant grass cover. It does pop up in hedgerows and grassland areas too so may yet prove more abundant.

False-brome (Brachypodium sylvaticum) appears to be living up to its reputation as a woodland species, recorded from just 13 (8%) monads to date. Most of this, as expected, take in areas of Newcastle’s wooded denes, though it occurs also in recent amenity woodlands, often on the site of former mines. Less often, this species colonises unshaded, neutral to calcareous habitats where it may be locally abundant. Perhaps the most prominent example of this are the banks of the Tyne at Elswick where it forms a distinctive understory below a range of planted and naturalised ornamental shrubs.

Hairy Brome (Bromopsis ramosa) is by all accounts a genuinely rare grass in the conurbation. Favouring shaded woodland with ample bare or disturbed ground, and just occasionally, mature hedgerows, it seems tied to the ‘wilder’ parts of the city, including Newcastle’s denes and several wooded nature reserves. I have only managed to record in 8 (5%) monads thus far but there are a few possible sites still to check.

Like the previous species, Bearded Couch (Elymus caninus) is a local scarcity, recorded from just 2 (1%) monads. It always has been with only 14 records held by the BSBI as of 2024, the last of which dates to 2011. So far, I have recorded this species from the edge of amenity woodland at Heaton Park, growing where recent works had disturbed the soil, and, rather oddly, from a gravelled front garden in Heaton. I suspect the latter may be the result of seed carried back from the aforementioned park.

Wood Melick (Melica uniflora), 2 (1%) monads, is a rare plant of rich woodland soils. In the greater Newcastle area, it is known historically only from the four city denes. Despite searching all to within an inch of their lives, I am yet to find it in Walbottle or Throckley Dene. Instead, I have observed it on just one occasion in more inaccessible parts of Sugley Dene – perhaps the least trodden of the city’s green spaces – and this week, I encountered in in two small areas of Jesmond Dene well away from areas of high footfall and disturbance. I do wonder if this species is genuinely declining as the health of such sites decreases.

Wood Meadow-grass (Poa nemoralis) seems only fractionally more widespread in the survey area at 5 (3%) monads so far. These correspond almost perfectly to its known range within the area with healthy populations at Havannah, Gosforth Nature Reserve, Jesmond Dene and Woolsington. It should be rather more widespread and indeed, on Friday, was discovered at a new wooded site at Killingworth.

Grassland Species

Yellow Oat-grass (Trisetum flavescens), 4 (3%) monads in total, is another grass with a patchy local distribution. I haven’t had much luck searching the city’s scant calcareous grasslands and with the exception of some former industrial grasslands along Scotswood Road, it seems mysteriously absent from many seemingly perfect areas of habitat. Instead, this species is most numerous on roadside verges near Woolsington, perhaps as an introduction, and around Big Waters Country Park. It is interesting to note that even within these grasslands it is far from common and very much lives up to its reputation as a ‘subordinate’ grass.

Quaking Grass (Briza media), recorded from 6 (4%) monads to date, is almost as picky and one could argue that all populations within the area stem from human introductions. The greatest concentrations occur on former industrial land at Scotswood and Silverlink, both sites which have been restored at one point or another. It is likewise likely introduced at Gosforth Nature Reserve and at further sites, is clearly a more recent escape. Wall tops in Heaton are far from it’s natural habitat.

Sheep’s-fescue (Festuca ovina) is a grass of free-draining, acid to calcareous habitats. Of the 9 (5.5%) monads in which it has been recorded so far, most match this criteria with the greatest concentrations being found on former industrial plots along the Tyne. It does, however, turn up outside of these places as demonstrated by records from a road verge at Gosforth and pastures at Big Waters. I suspect this is another I am guilty of under-recording.

Smooth Meadow-grass (Poa pratensis) is a perennial grass of verges, meadows and amenity grassland and is often found growing cheek by jowl with its more abundant cousin, Poa trivialis. It seems genuinely less plentiful than the latter and thus far, has been recorded from just 18 (11%) monads. This one is almost certainly under-recorded, particularly in areas rich in Poa trivialis where checking many plants may be necessary in order to find it. I suspect this one may be bumped up to the common and widespread list in due course. Smooth Meadow-grass often shares its habitat with another generalist, Tall Fescue (Schedonorus arundinaceus), 11 monads (7%), which appears rather more scarce and anecdotally, favours grasslands that are mown very infrequently (or not at all). So far, the best place to look for this impressive species has proven to be inaccessible road verges, roundabouts and central reservations which are often left to develop absent the constant landscaping that defines our city spaces.

Unlike Tall Fescue, Meadow Fescue (Schedonorus pratensis) is a genuinely rare grass. Recorded from just 4 monads (2.5%) so far, it seems to favour rough patches within established amenity grassland, I suspect where grass or ‘wildflower’ mixes have been sown in the past. Whether it occurs as a containment or a relic, I am unsure, but it is seldom numerous even where present.

Smaller Cat’s-tail (Phleum bertolonii), 6 monads (4%), has always been a rare grass in the area with just 14 records from four sites prior to this survey, usually from long-established grassland on nature reserves. That does not appear to be the true picture, however, as the species occurs scantly in a range of grassland types. It certainly occurs as a component of restorative seed mixes, as demonstrated by several records from sown grassland surrounding new build housing estates, and shows more of a tolerance for parched, infertile grassland than the similar Timothy. It is possible that particularly robust forms of this species, particularly where deliberately sown, have been under-recorded in favour of the larger species.

Wetland Species

Wetland areas are relatively scarce in the conurbation, a fact which largely explains the scarcity of grass species associated with watercourses and inundated areas. Of those which grow with ‘wet feet’ Floating Sweet (Glyceria fluitans) appears to be the most abundant, recorded from 10 monads (6%) so far. The relative success of this species can be explained by its tolerance of high nutrients and stagnation, with G. flutitans growing equally well in ditches and areas of arable run-off as it does in better-quality wetlands. Linked to this, Hybrid Sweet-grass (Glyceria fluitans x notata = G. x pedicellata) has been recorded from just 1 monad (0.6%) so far when it was found by John Durkin at Havannah Nature Reserve.

Reed Sweet-grass (Glyceria maxima), 7 monads (4%), occurs mainly as an introduction within the survey area. Growing within shallow areas of pools and lakes, or on nearby banks, it appears to have been added to several of the city’s wetlands for its ornamental value. Examples include Iris Brickfield Park, Rising Sun Country Park and various SUDS ponds in Gosforth. It may, however, occur naturally within marshland at Fencerhill Wood and Havannah Nature Reserve.

Not strictly a wetland grass, I admit, but one most often found close to water, Marsh Foxtail (Alopecurus geniculatus), found in 14 (8%) monads occurs predominately in waterlogged grassland. It may be locally abundant across successional brownfield sites and seasonally flooded grassland as seen at Iris Brickfield Park, Heaton, but also occurs around the margins of SUDS and urban lakes. Often at the waterside edge of communities dominated by common generalist grasses. I suspect it will prove much more widespread.

Reed Canary-grass (Phalaris aurundinacea) is by far the most abundant grass of the conurbations’ damp spaces, recorded from 44 (27%) monads so far. It can be found in almost all waterlogged areas notably including wet woodland, pool margins, seasonal floods and ditches, often forming dense monocultures where conditions are right. Two interesting observations surrounding this species include the presence of a variegated garden cultivar, var. picta, at several sites where it has been introduced, and the tendency of the species to outlive temporary wetlands. Such sites, commonly observed on the margins of arable fields or areas of brownfield, are rather abundant.

Finally, in this category, we have Common Reed (Phragmites australis). Occurring predominately in an introduced state, it can be found in most areas of suitable habitat but is dominant at only a few select sites. Most notably Gosforth Nature Reserve which holds the area’s largest reedbed. So far it has been recorded from 25 (15%) monads.

Heathland Grasses

Presumably much more widespread in prehistory, areas of lowland heath and acid grassland are now a rarity in the conurbation, concentrated in just a few corners of Newcastle. Further sites, most notably Prestwick Carr, sit outside the survey area and have not been surveyed on account of their rural appearance. The relative rarity of these habitats means that many of the grasses associated with them are confined to a few select sites, with a few notable exceptions.

The most prevalent grass of acidic swards is undoubtedly, Sweet Vernal-grass (Anthoxanthum odoratum), recorded from 16 (10%) of monads so far. This species can be prolific in such relic habitats, as seen at Gosforth Nature Reserve, but is much more of a generalist than other species within this category. It occurs in density within all relic acid grasslands but is present too in high-quality neutral grasslands and rarely, seemingly calcareous communities. There are undoubtedly still sites to discover for this one but it does appear scarce outside of these acidic communities.

Heath Grass (Danthonia decumbens) has always been a scarce grass in the survey area with only 12 historic records, the majority of which are ageing fast. Not recorded at all since 2004, during the present survey, it has been recorded from just 2 monads (1.2%), both times from ruderal ground close to relic heathland at High Gosforth Park. Similarly scarce, Matt-grass (Nardus stricta) has been recorded from just a single monad (0.6%) at Havannah Nature Reserve where it occurs amid Newcastle’s largest area of relic lowland heath. Both of these species were recorded from the former Brenkley Colliery in the early 2000s but searches of the site so far have failed to refind them. A challenge for local recorders?

Wavy Hair-grass (Avenella flexuosa) ought to be a little more widespread than it has proven so far. Recorded from just 5 monads (3%) to date, it shows a preference for woodland edge and rank grassland close to relic acid habitats, most notably at Gosforth Park, Big Waters and other locations in the North of Newcastle. It has also been recorded from brownfield land at Newburn.

Neither of the two common North East cottongrasses are species that anyone would associate with urban habitats, and they aren’t in truth, occurring in very low densities in isolated corners of the conurbation. Common Cottongrass (Eriophorum angustifolium), 1 monad (0.6%), is a very rare component of the relic heathland community at Havannah Nature Reserve, occurring across just a few metres of boggy land. It is also known from Prestwick Carr, outside of the survey area. Somewhat more surprising is the occurrence of Hare’s-tail Cottongrass (Eriophorum vaginatum) at Rising Sun Country Park in North Tyneside where it was found in 2024 by Joe Dobinson. The habitat here is by no means typical so it is safe to assume that it was introduced during the restoration of the various ponds on site. A process which also introduced Glyceria maxima and non-grass species such as Carex paniculata.

Saline Habitats

Saline habitats in the city are represented by two major habitat types: salt-strewn roadsides and relic saltmarsh and riverbanks along the Tyne. The latter is rather scarce, persisting in small pockets between Royal Quays and Wallsend to the East to Newburn in the West, while the former is far more widespread on account of our tendency to grit our roads in winter. We’ll cover the natural habitat first.

Common Saltmarsh-grass (Puccinellia maritima) would once have been much more widespread in the area but now exists in mere pockets where bare saline soils have been allowed to persist along the Tyne. Recorded from just 6 monads (3.5%) it is geographically rare but locally abundant at sites such as Walker, Elswick and Willington Gut. Higher up, amid the tidal defences and salt-sprayed walls that fringe the river, these sites too hold populations of Hybrid Couch (Elymus repens x junceiformis = E. x laxus), 5 (3%) monads. A cross between Common Couch (Elymus repens) and Sand Couch (Elymus junceiformis), it is interesting to note that Sand Couch has never been recorded within the survey area and was presumably lost when the river was altered quite some time ago. The hybrid between Sea Couch (Elymus athericus) and Sand Couch has also been recorded in Newcastle but alas, I am yet to find it.

And then we have our saline roadsides. Here, the only relatively widespread coastal grass species is Relfexed Saltmarsh-grass (Puccila distans) which to date, has been recorded from 17 (10%) monads. This species does well in the disturbed ground of verges and pavement cracks close to major roads and as such, is tied predominately to the area’s major throughaffairs where gritting is more prevalent. It is not the only grass to occur in such places, however, and chasing an old record by Gordon Young in Heaton, I was pleased to find Sea Fern-grass (Catapodium marinum) at its only known local site. Perhaps this one will yet occur more widely.

Bare and Disturbed Ground

Disturbed habitats in the city are usually dominated by several of the common and widespread species mentioned previously and increasingly, by Water Bent too. They do, however, host several somewhat more uncommon grasses which inhabit pavements, walls, roadworks, neglected stonework, rubble heaps and other such places.

Perhaps the most plentiful of these grasses is Fern-grass (Catapodium rigidum), recorded from 17 (10%) of monads so far. This inconspicuous little grass does well in a whole host of bare, parched and seemingly inhospitable habitats including wall-tops, pavements and roadsides but with the largest populations being found on the rubble and thin soils of demolition sites. It is easy to miss but is quickly revealing itself to be rather widespread.

Annual Beard-grass (Polypogon monspeliensis), 3 monads (1.8%) is an interesting one. It is widespread across the site of a now demolished brewery in Newcastle City Centre. How it got there remains unclear, but the disturbed, free-draining soils here seem to suit it well. Elsewhere, it occurs as a scant bird-seed alien in urban habitats but has shown itself capable of returning year-on-year in parts of Heaton. It is by no means a casual.

The two ‘tail-fescues’, told apart by their different-sized glumes, share a very similar taste in growing conditions. Both occur almost entirely on bare, free-draining soils, namely within parched amenity flowerbeds, stonework and neglected car parks. Both are rather scarce, though Squirreltail Fescue (Vulpia bromoides) is by far the most frequent, recorded from 12 (7.5%) monads vs the 1 (0.6%) monad of Rat’s-tail Fescue (Vulpia myuros). As annuals, these two are proving hard to account for in the present survey with only a limited window of opportunity to find them each year.

Four more rare grasses show a preference for bare or disturbed ground. Flattened Meadow-grass (Poa compressa) is easy to miss but has been recorded from 2 (1%) monads close to the Tyne at Walker. On both occasions, it was found to inhabit areas of derelict land. The final three grasses are predominately arable in nature and their relative scarcity may be partially explained by the exclusion of non-urban, arable monads at the onset of the survey. Black-grass (Alopecurus myosuroides) is a troublesome weed in Southern parts of the UK but remains rare in the North East. So far, it has been recorded from just 3 (1.8%) monads, where it was identified twice as a crop weed and once from an earthen mound on a building site. Great Brome (Anisantha diandra) has proven scarcer still recorded from 2 (1%) of monads, from an arable field and area of recent roadworks respectively, while Rye Brome (Bromus secalinus) has been recorded just once (0.6%) from arable margins at Callerton.

Alien Grasses

A large proportion of the grasses recorded in and around the conurbation occur due to human actions with many attributed to the import of materials, including bird seed and grain. More still occur as garden escapes and as contaminants of amenity seed mixes.

Birdseed and Grain Aliens

Of the birdseed aliens, Bread Wheat (Triticum aestivum) has proven the most abundant, recorded from some 19 (12%) monads so far. A key component of most budget seed mixes, it most often occurs as a casual within pavements and disturbed areas close to human habitation and in areas where waterfowl are regularly fed. The same applies also to Six-row Barley (Hordeum vulgare), 7 (4%) monads, and Two-row Barley (Hordeum distichon), 3 (2%) monads, which despite being far more common in cultivation nowadays, has proven itself scarcer in urban habitats than H. vulgare. Perhaps this is due to the make-up of cheaper, imported seed mixes? Millet (Panicum miliaceum), 1 (0.6%) monad, has also been recorded in such situations.

Some urban grasses associated with birdseed also occur unintentionally as contaminants. Of these, the Canary-grass (Phalaris canariensis), 3 (2%) monads, and Cockspur (Echinochloa crus-galli), 4 (2.5%) monads, have proven the most numerous. Both occur in similar settings to those mentioned above. A final species, Green Bristle-grass (Setaria viridis) also appears to owe its occurrence in the city to birdseed, observed in 2 (1.2%) monads so far.

As a final note on our birdseed aliens, last week I encountered my first example of Smooth-brome (Bromus racemosus) within the survey area. Growing within the pavement close to the margins of an urban lake where waterfowl are fed, one can only assume that this too occurred as a contaminant. There are, after all, no historic records of this native grass within the city limits.

Of the species linked to the import and export of arable products, Oat (Avena sativa) is the most widespread and has been recorded now from 10 (6%) monads where it predominately occurs on roadsides, presumably having blown from passing lorries. The occurence of Rye (Secale cereale) in a single monad (0.6%) in Gosforth can also likely be attributed to this.

Garden Escapees

Ornamental grasses are a key part of many gardens in and around Tyneside and while most are well-behaved and reluctant to spread, a select few have been recorded in a wild state. Most are casuals but a few species can now be defined as naturalised.

Of these, Greater Quaking-grass (Briza maxima) has proven the most abundant, recorded from 4 (2.5%) monads so far. Commonly grown as an ornamental annual, it has occurred for several years as a colonist of pavements, wall-tops and garden beds in Heaton and is particularly prolific in the grounds of a local school. Away from here, it has been recorded too from High Heaton, Jesmond and St. Peter’s. A second species, Rescue Brome (Ceratochloa cathartica) appears well naturalised in a single monad at Benwell where it appears to have spread from a garden to colonise an expansive area of ruderal ground. Recorded in 2023, this marked the first occurrence of this impressive grass in Northumberland.

Just a few weeks ago, another horticultural alien was discovered in the city when Chris Barlow stumbled across an impressive patch of Golden Oats (Celtica gigantea) at Big Waters, in the North of the survey area. How this got here is a bit of a mystery as the site is some distance from nearby habitation. One can only assume a stray seed, or perhaps deliberate introduction in this instance.

Other cultivated grasses are far more ethemeral in nature. A fortnight past, Hare’s-tail (Lagurus ovatus) was encountered by Pru Hamed growing in rough ground close to gardens in Heaton – the only record of this attractive annual during the survey so far. Finally, Argentine Needle-grass (Nassella tenuissima) has been recorded from 2 (1%) monads at High Heaton and Woolsington, on both occasions close to mass amenity plantings. Given how popular this one is in the hardy, low maintence displays created around new build estates and industrial complexes, I wouldn’t be surprised if we see much more of it.

Grass Seed

A final two urban grasses recorded in the city can roughly be attributed to grass seed mixes used to restore former earthworks. While it occurs too as a rare casual in other situations, Italian Rye-grass (Lolium multiflorum) is most numerous on landscaped road verges where presumably it is purposely spread for one reason or another. To date, it has been recorded from 7 (4.3%) monads in the conurbation.

Unlike the former species, Hungarian Brome (Bromopsis inermis), recorded from just a single monad thus far, presumably arrives unintentionally as a contaminant of grass seed. I have encountered this species just once growing on the margins of a restored pit heap at Burradon, though there are historic records from elsewhere.

And there we have it, a rather length tour of the urban grasses recorded so far during the project. I freely admit that the numbers shown here may, at present, be somewhat inaccurate. On account of their limited flowering time, grasses are proving a trickly bunch to nail down as part of the flora and as ever, recorder bias no doubt plays a part too. Cock’s-foot for example is much more obvious than Compressed Meadow-grass. So far, it seems I am doing a much better job at accounting for the very common and genuinely rare grasses in the city (I must try harder with those middling ones) but it is nice to see some trends beginning to emerge.

Now I am getting my eye in, there are a few more grasses that should materialise in due course. Despite searching, I have oddly been unable to locate Silver Hair-grass (Aira caryophyllea) and Early Hair-grass (Aira praecox) at any of their pre-2000 sites and have likewise failed miserably in my searches for Downy Oat-grass (Avenula pubescens) and Giant Fescue (Schedonorus giganteus), last reported in 2016. That one, at least, should still be out there while there are undoubtedly more aliens to discover also. Before embarking on this endeavour, I remember seeing a lovely roadside adorned with Foxtail Barley (Hordeum jubatum) but cannot for the life of me remember where…

Urban Flora of Newcastle – 2024 so far

As many of you may be aware, since 2022, I’ve devoted a significant portion of my spare time to documenting what I affectionately terming an ‘Urban Flora’ for Newcastle and the adjacent areas of North Tyneside. With spring fast approaching and activities set to pick up, I wanted to provide an update on progress so far. To give you a sneak peek: this winter has proven unexpectedly eventful, with numerous exciting discoveries and some intriguing trends starting to emerge.

Supposedly ‘Rare Plants’

One of the most interesting aspects of undertaking a survey such as this is the trends beginning to take shape for specific plants. Some, for example, are revealing themselves to be far rarer than expected while others are unexpectedly common. So far, several species featured on the Rare Plant Register for South Northumberland have fallen into the latter camp. Green Field-speedwell (Veronica agrestis) is a good example, listed as a regional rarity yet occurring in 23 (13%) of all squares surveyed so far, usually in flowerbeds, pavements or on the edge of lawns. The story is similar for Cut-leaved Dead-nettle (Lamium hybridum) at 15 (8.8%) squares and Great Lettuce (Lactuca virosa) at 17 (10%).

Several other plants, while not covered by the Registar, have also proven more abundant than anticipated. Among these, Bee Orchid (Ophrys apifera) has now been recorded from 17 (10%) of squares and interestingly, Glabrous Whitlowgrass (Erophila glabrescens) which while only found in 7 (4%) squares so far, is turning up wherever purposely searched for. I suspect most of this is down to the historic neglect of our urban spaces when it comes to botanical recording, but it is nice to see my recording efforts beginning to make a difference.

The Spring Bulb Conundrum

Spring bulbs pose an interesting challenge when recording the urban flora. Commonly introduced in great drifts along roadsides, hurled over garden fences and left to run wild in churchyards, it can be quite difficult to determine what exactly to record. For the purposes of this flora, a subjective judgement has been made wherein relic or seemingly naturalised populations have been recorded and newer introductions not. This has yielded some interesting results so far.

Snowdrops have been a real flavour of 2024 so far and it has been interesting to note both Greater Snowdrop (Galanthus elwesii) and Green Snowdrop (Galanthus woronowii) at several sites. Equally crocuses, easily the most abundant spring bulb, have recieved quite a bit of attention. Spring Crocus (Crocus neapolitanus) genuinely seems the most abundant in all habitats, whether as a relic or escape, but it has been nice to note Snow Crocus (Crocus x hybridus) and Yellow Crocus (Crocus x luteus) among others.

Add to these a suite other species in Siberian Squill (Scilla siberica), Alpine Squill (Scilla bifolia), Summer Snowflake (Leucojum aestivum) and most recently, Broad-leaved Grape-hyacinth (Muscari latifolium) and the late winter months have been most enjoyable. A nice warm-up for things to come in summer!

The Perks of New-Build Developments

Not something I thought I would write any time soon but I am quickly becoming enamoured with new-build developments. Particularly those under construction or only very recently completed. These estates with their copious areas of disturbed ground routinely yield some of the most diverse annual assemblaages in the city and so far this year, I have visited six. Parsley-piert (Aphanes arvensis), would appear rather rare in the city upon a glance at the distribution maps, but can be incredibly plentiful within these estates. Indeed, out of the five squares from which I have recorded it so far, four have been new-builds.

Other examples of plants strongly associated with these developments include Common Ramping-fumitory (Fumaria muralis), Bristly Oxtongue (Helminthotheca echioides), Field Pansy (Viola arvensis) and Great Lettuce (Lactuca virosa) while to a lesser extent, the same also applies to commoner plants like Charlock (Sinapis arvensis), Common Poppy (Papaver rhoeas) and Weld (Reseda luteola). I suspect some of these estates will yield further discoveries as the survey goes on and sadly for plants not reliant on disturbance, more land is dug up.

A few Suprising Finds

One of the true delights of surveying urban plants is stumbling across something unexpected. Since my last update, there have been plenty of exciting discoveries some of which are summarised here.

Back in Autumn, two county firsts were recorded from the West of the city in Rescue Brome (Ceratochloa cathartica), over-taking a small area of verge and nearby gardens, and Henry’s Honeysuckle (Lonicera henryi), bird-sown in a patch of relic scrub. Both are neophytes. Succulents too have proven interesting this winter with a county-second record of Tasteless Stonecrop (Sedum sexangulare) growing beneath a hedge in Gosforth and several records of Rock Stonecrop (Petrosedum forsterianum) from atop graves in local cemeteries. Speaking of cemeteries, a local botanist also brought my attention to a self-sown specimen of Noble-fir (Abies procera) in Jesmond – not one I was necessarily expecting.

Many of the more recent ‘new’ plants have been neophytes and more precisely, garden or amenity escapes. In Woolsington, Argentine Needle-grass (Nassella tenuissima) was noted sowing itself away from planted amenity beds, and recent walks have yielded records of other oddities in Virginia Stock (Malcolmia maritima), Western Red-cedar (Thuja plicata) and a plausible patch of Japanese Honeysuckle (Lonicera japonica) which will need revisiting later in the season.

Non-natives aside, however, there have been some interesting finds on the native front too. On Sunday, I was pleased to encounter what appears to be the areas only patch of Bilberry (Vaccinium myrtillus) growing on a bank at Willington and chasing a record from five years back, finally noted Whorled Water-milfoil (Myriophyllum verticillatum) at Havannah Nature Reserve. Also worthy of note are the Early Dog-violets (Viola reichenbachiana) discussed in this blog post.

Neophytes vs Natives

Spurred on by a conversation with botanist, Trevor Dines, I have been looking a little closer at the split between natives and neophytes (and archaeophytes too for that matter) in Newcastle and neighboring areas. Interestingly, of the plants recorded so far, 470 are native species vs 322 introductions. Just 52 are archaeophytes, meaning an almost equal split between natives and ‘aliens’ in the city.

This would appear to be substantially higher than several of the similar studies I’ve read and the reason for this remains unclear. Perhaps Newcastle genuinely is home to more alien plants or more likely, I am yet to record a great many of the native species lurking out there. Having excluded all dubious trees and shrubs, as well as mass plantings of bulbs and any species even suspected of having been recently planted, I’d like to think I haven’t over-estimated the neophytes too much.

Challenges this year

With most of the 169 squares included in the survey now surveyed at least once, 2024 looks set to be a year of gap-filling. Specifically, relating to plants appearing scant in the dataset so far. Grasses need a concerted effort during peak flowering season, specifically to map the common species that are most visible at this time, and aquatics need dedicated surveying at key wetland sites. Some willowherbs too are oddly lacking, though this is largely because they flower for but a short period and surveying them comprehensively is proving a pain!

Furthermore, there are a fleet of ‘missing plants’ still to find, or not. Looking at records post-2011, there are still a great many species lacking from the present dataset – Good-King-Henry (Blitum bonus-henricus), Small Melilot (Melilotus indicus), Small Teasel (Dipsacus pilosus) and Hungarian Brome (Bromopsis inermis) to name but a few. Whether these plants are still out there or not remains to be determined but I am certainly not above a spot of twitching to find out.

Beyond that, though I dread to think it, it am going to have to start learning my hybrid flora. Beyond the 10-15 recorded so far, there are many more that *should* be out there in the city. Broad-leaved x American Willowherb (Epilobium x interjectum), Oxford Ragwort x Common Groundsel (Senecio x baxteri), Field Horsetail x Water Horsetail (Equisetum x litorale), etc. There are even several historic records of interesting hybrid Oraches (Atriplex spp.) by the Tyne which may still pop up during the survey. All of this considered, 2024 looks set to be a fun year!

A few Thank yous

Surveying an area of this magnitude by ones self is a rather daunting task. For this reason, I am incredibly grateful to the various local botanists, and more general naturalists, sharing records too. It is wonderful to see more people looking closer at our urban plants and, in no particular order, thanks are offered to John Durkin, Chris Barlow, Philip Griffiths, Lydia Koelmans, Pru Hamed, Philip Shorrock and Joe Dobinson for their contributions so far. They really have been a big help.

Early Dog-violets in North Tyneside

A slightly different blog this week with a surprising local discovery and, happily, a tale of success.

Back in 2022 I visited Silverlink Park in North Tynside and was suprised to discover a small population of ‘curious’ violets growing on a former rail embankment amid a tangle of bramble scrub. A little paler in colour, they had the look of Early Dog-violet (Viola reichenbachiana), and after the record was submitted, were prompty confirmed as such confirming the rather odd occurence of this species in the heart of urban Tyneside.

For context, while common in parts of the south, Early Dog-violet is a rare plant in Northumberland. Known from just a handful of ancient oak woodlands in the south of the county, it features on the Rare Plant Register for South Northumberland and historically, isn’t one to crop up outside of its core range. With this in mind, the discovery of a small colony growing atop an unassuming patch of brownfield in the city gave much cause for excitement. Had they escaped a local garden? Had they been imported with soil when the site was restored? Who knows, but this unassuming green space does have a habit of throwing up curiosities from time to time.

Fast forward to early 2024 and I am pleased to say that this small colony is expanding rapidly. On Saturday, I counted approximately 50 plants scattered over an area of around about 20m. More suprising still, however, was a report of an even larger colony discovered a few days prior by local naturalist, Joe Dobinson, at Rising Sun Country Park – just a few miles down the road from Silverlink. Again, these plants were observed growing in woodlands and scrub close to a busy footpath, but unlike the former population, there were hundreds, perhaps suggesting that they have gone unreported for some years or at the very least, the smaller Silverlink population was in fact an offshoot.

The occurence of this typically rural plant in the city – and the area covered by my current urban flora project – is definitely intriguing and if these sightings are anything to go by, it may expand further still. It would pay for local botanists to be on the look out in scrubby areas nearby, and perhaps the various urban woodlands that dot the area. What do you look for exactly?

Early Dog-violet is seperated from the very similar Common Dog-violet (Viola riviniana) by its spur shape and colour. In Common Dog-violet, the spur is curved upward and paler than the petals, in Early Dog-violet the spur is straight and noticably darker than the petals. The petals of Early Dog-violet are usually more erect but really, all you need to look at is that pesky spur.

If you spot this plant anywhere across Newcastle and North Tyneside, I’d love to hear from you.

Urban Flora of Newcastle – Musing over maps

With recording for ‘Plants of Newcastle’ progressing well and new local botanists joining in, for the last few weeks, I’ve been able to catch up on some of the more mundane parts of the project. Top of that list was a need to ‘reaquaint’ myself with some sort of GIS programme, hopefully to save a few pounds when it comes to the final write-up.

Now, I am happy to admit I am rather rubbish at anything techy like this. I loathed GIS modules at university and haven’t touched any sort of mapping software in almost a decade. Still, downloading QGIS (supposedly one of the easiest to use platforms) I thought I’d give it a go. While they may be rough around the edges, I am pretty pleased with the result!

Below, I have included a few example maps created for some interesting urban plants, but what exactly do they tell us?

Oxford Ragwort (Senecio squalidus)

Oxford Ragwort is perhaps the most consicous example of an established neophyte (human introduction) in Newcastle. The story of this tenacious little plant is well-known and according to records held by the BSBI, it arrived in the city sometime around 1960 where it was first recorded by George Swan from the Town Moor. Known to favour dry, rocky subsrtates (especially pavements and railway clincker) it is perhaps unsurprising that most of the records so far come from heavily urbanised areas. Indeed, it is exceptionally abundant in the city centre and suburbs but altogether scarce in more natural areas to the North and West. A trend to be expected, perhaps.

Guernsey Fleabane (Erigeron sumatrensis)

Guernsey Fleabane is a relatively new arrival in Newcastle, first recorded in 2009 by Mick Crawley. Across the UK, it is ungoing a dramatic expansion as it follows in the footsteps of Canadian Fleabane (Erigeron canadensis) to become a familiar weed of urban habitats. Since it was first noted on Dean Street, it appears to have expanded outward to colonise much of the city centre and neighboring districts, with the greatest concentrations on wasteground plots in Heaton, Walker and Jesmond. It will be interesting to see if these initial maps hold true, or whether it is already far more widespread.

Italian Alder (Alnus cordata)

Italian Alder is an incredibly popular amenity tree in Newcastle, frequently planted along streets, in muncipal landscaping schemes and seemingly, on restored industrial land. It is also a prolific seeder capable of colonising a whole host of disturbed and wasteground habitats. The records shown below represent seemingly self-sown specimens of Italian Alder and it is interesting to note a strong southerly bias. I suspect this corresponders to the high level of industry along the Tyne and our tendency to cover-up defunct sites with all manner of interesting trees?

Welsh Poppy (Papaver cambricum)

Welsh Poppy, native elsewhere in the UK but certainly not in Newcastle, is an interesting example of a plant that thrives in gardens. Indeed, most of the time, this attractive plant is observed as a colonist of flowerbeds, driveways and patios where I suspect is left by usually diligent weeders on account of its pretty flowers. It is interest to note that the distribtion of Welsh Poppy appears linked to the presence of larger gardens, with suburban areas holding large populations and relatively few records from the city centre. While not always the case, it also appears reluctant to colonise more natural areas.

Lords-and-Ladies (Arum maculatum)

In contrast to Welsh Poppy which seems to favour artifical environments, I thought it would also be interesting to explore the distribution of a species associated with more natural ones – cue Lords-and-Ladies. Unspurisingly, almost all records of this popular woodland plant come from relic semi-natural woodland, namely in Newcastles denes at Walbottle, Throckley and Jesmond. I wouldn’t be suprised if this one crops up elsewhere, likely beneath a hedgerow, but it will be interesting to see if the same applies to other indcator species like Wood Anemone and English Bluebell.

The Plants of Newcastle – online talk

A few weeks ago, I had the pleasure of delivering my first ever talk to a room full of botanists (eek!) at the BSBI British and Irish Botanical Conference in Newcastle. The subject? Our fantastic urban flora, of course, and specifically, my findings so far while recording for what I am loosely coining ‘The Plants of Newcastle’.

All in all, it was lovely (if tad scary) to share my work recording Newcastle’s urban plants with around 200 delegrates. Due to some technical issues on the day, live recording was not possible but thankfully a digital recording is now available on the BSBI YouTube channel. Do check it out below if of interest.

I’ll be using the winter to carry out a few more surveys as part of the flora, and to start writing. I hope I’ll be able to share a finished product with you in due course.

10 Coastal Plants Colonising the City

Take a closer look at the coastal plants or halophytes spreading along roadsides to colonise the city.

The term ‘halophyte’ refers to a plant tolerant of higher than usual salt levels. Typically, this means coastal plants that are regularly exposed to sea spray, submersion by saline water or soils saturated with salt.

As you might imagine, the distribution of these hardy plants would once have been limited to salt marsh, cliffs and other habitats by the sea though now, this is changing. Owing to the large quantities of salt spread to ward off ice along our roads, several of these typically coastal plants have now made the jump inland to occupy inhospitable margins of roads in our towns and cities.

While recording for ‘The Plants of Newcastle‘ it has become increasingly clear that our urban halophytes are not restricted to the few familiar species so many of us encounter on a daily basis. In this blog, I thought we’d take a closer look at some of the most frequent.

Buck’s-horn Plantain (Plantago coronopus)

A perennial of short-cropped often trambled habitats, Buck’s-horn Plantain has historically been associated with two distinct habitats. It occurs widely around Britain’s coastline where it inhabits sea walls, dunes and shingle but is also known from heathland and other inland habitats in the South. In Northern England, it is very much a coastal plant but now, is occurring more widely as a colonist of urban habitats close to roads.

Across Newcastle, I am now seeing this plant pop up on roadside verges close to major transport links, typically where grassy areas are subject to regular mowing. It is most often encountered on the margins of such places where dominant grasses have been killed off by regular salting.

Buck’s-horn Plantain is best identified by its distinctive rosettes of lanceolate, lobed leaves.

Sea Plantain (Plantago maritima)

The aptly named Sea Plantain is another typically coastal species. Here, you’ll most often spot it on the upper reaches of salt marsh, atop sea walls or strewn across shingle beaches. It also occurs in upland areas of Scotland and Northern England where it inhabits species-rich pasture and streambanks. Traditionally, it was absent from much of the lowlands but this again is changing.

Like Buck’s-horn Plantain, this one does well on short-cropped grassy verges regularly exposed to salt kicked up by passing vehicles. Locally, it remains scarcer than the former species but in Newcastle at least, is showing signs of colonisation in several areas including Gosforth and Heaton, typically a stone’s throw from major roads.

Sea Plantain can be separated from other plantago species by its long, smooth strap-like leaves.

Sea Fern-grass (Catapodium marinum)

An annual grass of dry, bare places by the sea, Sea Fern-grass is a pretty scarce plant in North East England, even on the coast. Like the other plants on this list, however, across the UK it appears to be colonising inland sites along salt-treated roads, particularly in Southern England.

In Newcastle, a sizeable population of this coastal grass can be found on the concrete sidings of the aptly named Coast Road in Heaton, as well is in nearby pavements and the bare margins of grass verges. Due to the similarities between this and Catapodium rigidum, it may well be under-recorded and is one worth searching for while botanising the city.

Sea Fern-grass can be separated from the far commoner Fern-grass (Catapodium rigidum) by its larger spikelets.

Reflexed Saltmarsh-grass (Puccinellia distans)

Another coastal grass and one which is rapidly colonising our urban spaces. As its name suggests, Reflexed Saltmarsh-grass is most commonly encountered in muddy habitats on the coast, typically on the upper edges of saltmarsh. Inland, it favours stonework, pavements and areas of heavy soil close to salt-treated roads.

In Newcastle, at least, this is one of the more abundant halophytes and can be found right across the city, typically along major roads which are subject to the most intensive treatment in winter.

Interestingly, a close relative, Common Saltmarsh-grass (Puccinellia maritima), remains largely restricted to coastal habitats, both here and further afield across the UK. I wonder why?

Sea Aster (Tripolium pannonicum)

A rather beautiful member of the daisy family, Sea-aster is most commonly associated with grazed salt marshes and coastal creeks. It is known to be reluctant to spread inland via salt-treated roads but has been observed to do so in isolated parts of the country.

Locally, I have observed this plant growing in gutters and roadside depressions close to busy main roads, presumably where water saturated with salt gathers for extended periods of time. It is far from the commonest halophyte in the city but does pop up from time to time, though seldom in large quantities.

Lesser Sea-spurrey (Spergularia marina)

Vying with Danish Scurvygrass for the title of our commonest urban halophyte, Lesser Sea-spurrey is an incredibly common sight in urban pavements, roadsides and verges. A sprawling plant with attractive pink and white flowers, it would once have been associated solely with muddy shingles and grassland by the sea.

In Newcastle, this one can occur almost anywhere. The greatest concentrations are likely to be spotted along roads but I have also observed in alleys, side streets, garden walls and occasionally, on driveways – presumably where residents apply salt.

Of all the coastal plants on the march in our towns and cities, this one has undergone perhaps the most remarkable expansion over recent years.

Danish Scurvygrass (Cochlearia danica)

The standout urban halophyte and a plant which needs very little introduction, Danish Scurvygrass has undergone a remarkable expansion since the 1970s to colonise most towns and cities across the UK.

A member of the cabbage family with chubby, heart-shaped leaves and attractive lilac flowers, this plant flowers from February onwards adding a touch of colour to pavements and roadsides at a time when little else is in bloom.

Hinted at in its name, Danish Scurvygrass, alongside Common Scurvygrass (Cochlearia officinalis), was once used to prevent scurvy aboard ships due to its high Vitamin C content.

Spear-leaved Orache (Atriplex prostrata)

Historically a plant of beaches, shingle and saltmarshes, Spear-leaved Orache is now a very common sight inland. For quite some time, it has occurred as a ‘weed’ of agricultural land, refuse tips and wasteground plots but in recent years has also spread along our urban roadsides.

A tad more abundant than another orache featured later in this list, this one is still very much in the process of colonising our cities. Data from the BSBI now shows it occurring in almost all 10km squares across England, with notable increases in Ireland and Wales.

In Newcastle, Spear-leaved Orache is a prominent sight in gutters and concrete sidings within the ‘spray zone’ of most major roads.

Grass-leaved Orache (Atriplex littoralis)

A second orache now and one which is rapidly colonising a plethora of urban habitats both in Newcastle and further afield.

With distinctive, slender leaves, Grass-leaved Orache is one Atriplex that shouldn’t confuse passing botanists and typically inhabits silty habitats by the sea. Like the others on this list, it is increasing inland most notably along our roads. This spread has been most pronounced since the 1980s and now, it is a fairly common sight in urban areas; though in in experience, it remains scarcer than the aforementioned Spear-leaved Orache.

Annual Sea-blite (Suaeda maritima)

A rarer one now and a plant which remains very scarce indeed in urban habitats. So much so that it barely warrants inclusion on this list!

Annual Sea-blite is a succulent plant typically encountered in the upper and middle zones of salt marshes. It seldom occurs inland and unlike the other halophytes on this list, is reluctant to colonise salt-treated roadsides. That said, it does occur in the city.

While recording for the Plants of Newcastle I was genuinely surprised to encounter S. maritima in walls and stonework at several points along the River Tyne. Most notably on the Newcastle/Gateshead Quayside. Now, the Tyne remains fairly saline here so perhaps this should come as little surprise but it is included nevertheless due to its occurrence some distance from ‘typical’ habitat. Indeed, where I have observed it, it has been growing well out of reach of the Tyne’s saline waters. I do wonder if it may appear at further sites in the near future.

10 Urban Plants on the Rise in Newcastle

Just for fun, take a quick look at 10 urban plants currently on the increase across Newcastle-upon-Tyne.

Our urban habitats are dynamic ones and when it comes to wildlife, things are always changing. This is perhaps most obvious in our wild and naturalised plants as new species arrive, others decline and our alteration of the landscape provides new opportunities for colonisation. While recording for ‘The Plants of Newcastle‘, it is becoming increasingly clear to me that certain plants are doing far better than others, and for a variety of reasons. Many of these are non-natives (neophytes) perfectly suited to the urban environment, while others are a tad more surprising. Just for fun, I thought we would take a look at ten of the most obvious examples here.

Guernsey Fleabane (Erigeron sumatrensis)

A tall, annual herb of well-drained, disturbed soils in gardens, along roadsides and in paved areas, this conspicuous plant is doing really well at present. A native of South America, it was first recorded in the UK from Guernsey in 1961 and has since spread across much of Southern England. Currently marching North, it is now fairly widespread in areas of the midlands and along the West coast but until recently, was rather rare this far North. This now appears to be changing and, since the first Newcastle record in 2009, appears to be expanding rapidly.

So far, I have observed Guernsey Fleabane from several city centre squares, as well as multiple suburban areas. In places such as Heaton and Walker, it even appears to be overtaking Canadian Fleabane (Erigeron canadensis) as the most numerous small-flowered species present.

Like Canadian Fleabane, Guernsey Fleabane has very small seeds which as easily dispered on the wind. If trends in the South are anything to go by, I suspect it will go on to become one of our most familiar urban plants.

Narrow-leaved Ragwort (Senecio inaequidens)

First recorded in Newcastle in 2012 by Quentin Groom, Narrow-leaved Ragwort shares a similar story to Guernsey Fleabane. First recorded on our shores in 1836, for a long time, this attractive plant remained a scarce casual occurring as a contaminant of wool shoddy. Since 1999, however, it has rapidly expanded along transport links (much like the story of Oxford Ragwort) and is now a familiar sight across much of Southern England and the Midlands.

Like the former species, this plant becoming increasingly prominent in the North at present and in Newcastle, is now appearing in a range of urbanised habitats, from recently disturbed roadsides to neglected front gardens. Interestingly, Narrow-leaved Ragwort appears most abundant in squares adjacent to the River Tyne; though for how long this will last I am unsure.

Pirri-pirri-bur (Acaena novae-zelandiae)

Now this is an interesting one. A native of Australia and New Zealand Pirri-pirri-bur has been known from the Northumberland coast for many years. Here, it’s tenacious seed heads cause havoc for people and wildlife alike and are much maligned by land managers. While it is known to inhabit inland sites locally, most notably forestry tracks in the uplands, it is seldom thought of as an urban plant. Indeed, with only two recent records from Newcastle, we seem to have escaped it thus far.

Fast forward to the present day and this appears to be changing. I have now recorded Pirri-pirri from several habitats vastly different to the dunes in which I am accustomed to seeing it. Among these, relic heathland, wooded tracks, a church lawn in Gosforth and even on gravel driveways in High Heaton. While it is far from abundant, yet, I suspect this one may continue to increase in the future.

I do wonder if these initial colonies have their roots in populations on the coast, perhaps brought in by a passing dog or unsuspecting hiker? Either way, Pirri-pirri may go on to become one of our most unwelcome urban plants.

Italian Alder (Alnus cordata)

An attractive tree from Corsica and Southern Italy, Italian Alder was first introduced to the UK in 1820. To this day, this species remains a popular plant in landscaping and municipal planting schemes, a factor very much evident in Newcastle with rows of planted trees present on high streets and roadsides in various corners of the city.

Italian Alder is known to set prolific quantities of seed. This, coupled with a tolerance of dry, low-nutrient soils, means it is able to colonise a range of disturbed habitats in the city. Presently, it is particularly numerous along rail links and across areas of brownfield land in the city but increasingly, is also appearing as a weed in residential areas. In Heaton alone, I have noted this tenacious tree growing in pavements, gutters and even garden lawns, and the same appears to be true in Walker, Shieldfield and other districts.

Hjelmqvist’s Cotoneaster (Cotoneaster hjelmqvistii)

As one of my favourite groups of plants, I had to include a cotoneaster on this list somewhere. Now, several species of alien cotoneaster are already rather widespread in Newcastle but until recently, Hjelmqvist’s Cotoneaser was not one of them. With just a single 2012 record from Ouseburn, it appears that it was historically quite scarce. This is certainly not the case now and this year alone, I have recorded this attractive species from eleven separate city monads, in a whole host of habitats. Like most cotoneasters, this one does well in stonework, walls and structures but also occurs in urban hedges, rail sidings, woodland and derelict land.

Like many cotoneasters, this species is popular cultivation and owing to the copious fruits it produces in autumn, is a draw to passing birds. It is for this reason that it has been able to spread so widely in Newcastle and is why it is usually observed as isolated plants. As I write this, a fine example of Hjelmqvist’s Cotoneaser is also growing under my garden bird feeders. Not planted, it surely must have arrived with a visiting thrush or pigeon.

Ragweed (Ambrosia artemisiifolia)

The first birdseed alien on this list and one which represents perfectly a group of plants on the increase as a result of bird feeding.

A native of North America, Ragweed has been recorded as a casual in the UK since 1829 and is known to occur predominately as a contaminant of arable produce including animal feed, grain and oil seed. Nationwide, it occurs in a whole manner of habitats where its spread is limited only by harsh frosts.

With just a single record in Newcastle prior to the current survey at Walker Riverside in 2006, it seems this species has always been somewhat scarce locally. Is this changing? Well, in 2023 alone I have recorded it from four separate locations, three of which were urban parks where it finds a home in lakeside stonework close to where locals feed waterfowl. I have also observed it growing within pavements in Heaton, albeit close to bird feeders.

Interestingly, I first observed Ragweed in Leazes Park, one of the three sites mentioned above, in 2021. It has occurred there every year since but whether this is the result of continued introductions or evidence of a self-sustaining population, I am uncertain. Either way, it seems to be on the rise.

Greater Quaking-grass (Briza maxima)

The first alien grass on our list now with Greater Quaking-grass, a striking species native to the Mediterranean.. This annual grass is a fairly common sight in gardens and, seeding prolifically, is now common in Southern parts of the UK where it inhabits a variety of dry, bare habitats from pavements to arable margins. The naturalised range of this species does not extend into Northern England and, in my limited experience, populations here tend to be isolated and located close to gardens.

Prior to 2020, there were just three records of Greater Quaking-grass in Newcastle, notably coming from Jesmond and Heaton. In the latter of these, this grass is now a common component of our urban flora occurring on wall-tops, within gardens and across areas of pavement. Furthermore, it is now showing signs of spread with records from roadsides in High Heaton, Walker and St. Peter’s Basin. Given the trend elsewhere in the UK, I suspect we’ll be seeing much more of it in the future.

Water Bent (Polypogon viridis)

If the story of Briza maxima is a successful one, that of Water Bent is one of rampant success. Known as one of the ‘fastest spreading’ plants in the UK, this native of Southern Europe first arrived on our shores, or at least Guernsey’s, in 1860. For quite some time, it failed to move beyond the Channel Islands but in recent years, has undertaken a rapid advance North through Britain. It first reached Newcastle in 1981 but was not recorded again until 2022. In the time since (a mere two years), it has gone on to colonise several parts of the city and is now a familiar site along roads, wall bases and paved areas in Heaton, Jesmond, Manors and even in the heart of the city centre.

With isolated records now from Scotland, this plant is still very much on the move; though it still has some consolidating to do in Newcastle. Still, if the last two years are anything to go by, numbers can only go up.

Small Scabious (Scabiosa columbaria)

Now, given that neophytes have dominated this list so far, you would be forgiven for thinking that alien species were the only ones doing well in our urban species. This is definitely not the case and several native species are also on the increase, including those introduced for their aesthetic value. Foremost among these in Newcastle seems to be Small Scabious, a species associated with hills, slopes and banks on calcareous soils elsewhere in the country. In South Northumberland, it is a rather rare plant, so much so that it warrants a place on the county’s Rare Plant Register; though in Newcastle at least, this is changing.

Small Scabious appears to be a regular component of seed mixes used by councils on derelict ground and poor soils. It has been introduced to several sites locally including Walker, Scotswood and Gosforth in this exact fashion. All of this means that its natural distribution, if indeed it was present locally, has been greatly masked. In total, I have now recorded this species from around a dozen squares where it seems to persist and spread quite readily on former industrial soils.

Small Scabious (Scabiosa columbaria) © Chris Barlow

Bee Orchid (Ophrys apifera)

A nice one to finish on and an example of a native species exhibiting a welcome spread into Newcastle’s urban habitats. Formerly a very rare plant, Bee Orchid is becoming increasingly abundant in a whole host of habitats across the city, from urban lawns and roadside verges to brownfield. It has now spread to such an extent that it is the orchid most likely to be encountered in built-up habitats.

Formerly a species of Southern counties, Bee Orchid was first recorded within the city in 2002. Since then, records have grown in frequency, reaching a peak in 2023 wherein it was encountered city-wide, including on a city centre lawn. This spread is thought to be a result of favourable climatic conditions and if this year is anything to go by, Bee Orchids will be brightening up our city’s greenspaces for many years to come.

An Urban Flora of Newcastle – One Year On

A project update following a busy old year surveying the urban flora of Newcastle.

As many readers of this blog will know, for the past twelve months I’ve been dedicating almost all of my free time to what I am loosely calling an ‘Urban Flora of Newcastle’. This, I hope, will at some stage become a publication that sets out the abundance and distribution of all wild plants growing within the city limits, along with information on our botanical hotspots, habitats and other key features. Well, after a hectic year, now seemed like a good time for an update.

I already have written about this project several times (here, and here, for example). With so much time in the field, you might think that I’d have cracked it by now but truly, things are only getting more interesting as new species crop up, interesting sites are discovered and certain trends become clearer. We’ll start with the headline facts, however…

The Survey

At this stage, I have now spent 245 hours in the field and carried out 110 visits to 90 of the 143 monads that make up Newcastle-upon-Tyne. No easy feat while working a full-time job, I tell you. Some of these squares (I will call them that for simplicity) have been visited upward of five times while others, just once. I will need to visit each multiple times in all seasons to do even a remotely good job.

During my time rummaging around in the city’s alleys, car parks, side streets and occasionally, more appealing green spaces, I have now recorded 790 species growing in a wild or naturalised state. Of these, roughly a quarter are neophytes – human introductions. A far smaller portion arre what we would call archaeophytes, the historic introductions, while most are simply native plants etching out a living in the city. An interesting mix to say the least.

With several more recorders now regularly surveying the city, these records are now being supplemented by new additions to the BSBI database and iRecord which should go some way to painting an accurate picture of the flora here. With the best will in the world, a single person cannot find every plant in every square…

Our Commonest Plants

It will come as no surprise to learn that a select bunch of plants have thus far been found in each and every square. These are often habitat generalists or those who have adjusted to life perfectly in the urban environment. So far, they include White Clover (Trifolium repens), Wood Avens (Geum urbanum), Annual Meadow-grass (Poa annua), Nettle (Urtica diocia), Cleavers (Galium aparine), Smooth Sow-thistle (Sonchus oleraceus), Daisy (Bellis perennis), Dandelion (Taraxacum agg.) and Bramble (Rubus fruticosus agg.).

Following close behind these is another suite of species which may well prove omnipresent. Examples include Sycamore (Acer pseudoplatanus), Broad-leaved Dock (Rumex obtusifolius), Greater Plantain (Plantago major), Red Fescue (Festuca rubra), Knotgrass (Polygonum aviculare).

Only Hawthorn (Crataegus monogyna) and Wild Cherry (Prunus avium) have surprised me with their abundance as a component of our urban flora. Otherwise, much of this could have been guessed in advance!

Birdseed Aliens

Over recent weeks, I’ve been paying closer attention to areas where the feeding of birds is commonplace. Such places often hold a wealth of cultivated and contaminant plants linked to stray seeds. This has proven worthwhile with plenty of records of the common escapees in Sunflower (Helianthus annuus), Oat (Avena sativa), Bread Wheat (Triticum aestivum), Six-row Barely (Hordeum vulgare) and interestingly, Ragweed (Ambrosia artemisiifolia), a stowaway from North America.

These places have also yielded surprises too with Canary-grass (Phalaris canariensis) found on a street in Heaton, Cockspur (Echinochloa crus-galli) at two locations, Two-row Barely (Hordeum distichon) and yet more Niger (Guizotia abyssinica). I do wonder what might emerge in such situations during the rest of the survey.

Suprisingly Abundant Plants

Earlier, I mentioned trends becoming clearer. One such trend comes from my own biased underestimation of the abundance of certain plants I had assumed were rare in the city. Marsh Woundwound (Stachys palustris), while far scarcer than Hedge Woundwort (Stachys sylvatica), seems to grow in a far wider range of habitats than previously thought, including entirely dry ones, while Great Mullein (Verbascum thapsus) is a surprisingly abundant pavement plant.

Other examples include the recent colonist Water Bent (Polypogon viridis), which seems to be gaining ground almost daily and Great Lettuce (Lactuca virosa) which while listed on the county Rare Plant Register, grows almost anywhere.

Perhaps I am just ‘getting my eye in’ but equally, Relfexed Saltmarsh-grass (Puccinellia distans) seems far more widespread than anticipated along salted roadsides too. The list goes on.

New additions

Aside from the interesting aliens listed above, the past few weeks have brought several firsts for the urban flora. Vervain (Verbena officinalis) in Leazes Park, found by Philip Griffiths, Flax (Linum usitatissimum) on a residential street and Ivy-leaved Cyclamen (Cyclamen hederifolium) oddly growing on a verge beneath an underpass in the city centre. The latter did not look obviously planted and may stem from when the road was created.

On a recent trip to Big Waters, a nature reserve managed by Northumberland Wildlife Trust, Matt and I were lucky to find several areas of Great Duckweed (Spirodela polyrhiza), rare up here, as well as Rigid Hornwort (Ceratophyllum demersum). Havannah Nature Reserve, ever throwing out interesting plants, revealed Marsh Cudweed (Gnaphalium uliginosum) and Gosforth Nature Reserve surprised with Blue Water-plantain (Veronica anagallis-aquatica).

Closer to home in more gritty, urban habitats the surprises have continued also. Chasing an old record from Gordon Young, I was pleased to encounter Sea Fern-grass (Catapodium marinum) growing on a roadside wall in Heaton while Chick Pea (Cicer arietinum) staddling a wall in an inner-city cemetery at Fenham came as somewhat of a surprise.

Another oddity comes from Cabbage Thistle (Cirsium oleraceum) in woodland at Armstrong Park – I wonder how long that has been lurking there? Truly, you never know what will crop up in the city!

Emerging Priorities

While botanising the city, there have been several groups I have ignored until now and a few communities that have been poorly surveyed. That means that once I have finished my initial sweep of all squares this year, there’ll be several blank spots to fill in 2024.

Aquatic plants – so far these have only been lightly surveyed where specimens are located close to banks or at least within reach with the aid of wellies. I’ll soon be investing in a grapnel to hopefully begin a more thorough exploration of these next year. There must be some exciting pondweeds lurking in the city’s pools and lakes…

Polypodies – thus far, all polpodies have been aggregated but with the help of our new microscope, I plan on taking a closer look at these soon. Those in the city’s wooded denes must surely be Common Polypody (Polypodium vulgare) but those on city walls may yet prove different.

Spirea agg – I’m rather rubbish at these but with several naturalised spirea existing in various corners of the city, I’ll be making a concerted effort to learn very soon. Starting with that growing on the railway lines by my house!

Grasses – I’d like to feel that I’ve put a good dent in the city’s grasses in 2023. However, it is difficult to record each and every one while simultaneously recording everything else. Next year, I think many squares will need revisiting with the sole intention of recording grasses (and possibly carex too).

These targets aside, I look forward to another year spent exploring our urban flora. It really is incredible what can be found within build-up, seemingly inhospitable environments and the relics of our natural ones strewn among them. With 39,000 words written so far, I sincerely hope I am able to do something with this beyond just blogging about it in due course!

Newcastle’s Urban Flora – A Project Update

An account of a busy season recording for what I’m loosely calling an ‘Urban Flora of Newcastle‘.

As many of you will know, over the past year, I’ve been working on a project to map the urban flora of Newcastle-upon-Tyne – a personal endeavor that I hope at some stage to publish.

With 82 out of 105 monads (1km grid squares) across the city now visited, often several times, some 200+ hours of time, and 32,000 words written, now seemed like the perfect time to give a wee update. Spoiler: with some 760 plant species, hybrids or subspecies now recorded this is quickly shaping up to me a mammoth task!

Common plants

Visiting so many sites across Newcastle, it is quickly becoming apparent which are our most successful urban species – the true city specialists! So far, some 15 species have been recorded in each and every square and none of these have come as a suprise. Cleavers (Galium aparine), Smooth Sow-thistle (Sonchus oleraceus), Groundsel (Senecio vulgaris) and Daisy (Bellis perennis) are some familiar examples present in just about every pavement crack, rough patch or lawn if time is taken to look.

Other examples include Creeping Buttercup (Ranunculus repens), Yarrow (Achillea millefolium) and of course, Annual Meadow-grass (Poa annua). The omipresent city plants!

Totting up the ‘top 25’ most recorded plants hasn’t revealed many suprises, in truth. Hawthorn (Crataegus monogyna) and Wild Cherry (Prunus avium) are a little more abundant than anticipated and Meadow Buttercup (Ranunculus acris) has surpassed expectations, but that’s about it. But we knew this already…

Rarities and Surprises

On the reverse, while many plants are terribly common in the city, others are not. I’ve found my far share of rarities and neophyte oddities while recording so far but what is more suprising is that they just keep coming.

Just yesterday, while grubbing around Scotswood I encountered several species new to me – Perfoliate Alexanders (Smyrnium perfoliatum), Straw Foxglove (Digitalis lutea), Upright Spurge (Euphorbia stricta) and Wild Madder (Rubia peregrina). Each somewhat out of place but interesting nontheless.

Other interesting records of late include the white form of Dark Mullein (Verbascum nigrum) on a messy city verge, a new population of Hairy Bindweed (Calystegia pulchra) engulfing a city cemetery and even House Holly-fern (Cyrtomium falcatum) growing in a gutter in Gosforth. Our urban flora if nothing if not diverse. I do wonder what else might pop up during the remainder of the survey?

It isn’t just hortals and neophytes surprising however, and some of our scarcer native species are actually proving rather abundant. Cut-leaved Dead-nettle (Lamium hybridum) is a good example, popping up just about anywhere, while Hare’s-foot Clover (Trifolium arvense) seems more widespread than anticipated in neglected carparks and building sites.

Hoary Mustard (Hirschfeldia incana), rare? Nope. Bee Orchid (Ophrys apifera)? More abundant than you might think. What about Great Lettuce (Lactuca virosa), a Rare Plant Register species? Everywhere! The mind boggles.

Overlooked Plants

Embarking on a project such as this, there were always going to be groups which were under-recorded, either due to ‘recorder blindness’ or simply the effort needed to check many plants that superfisially look the same. Willowherbs (Epilobium sp) and yellow composites are good examples of the former – how often do simply walk past these? Cotoneasters an great example of the latter. Recently, I’ve been trying to counteract this by focusing on these groups in greater detail.

The willowherbs have proven particularly eye-opening. Close to home in Heaton, a single stretch of pavement held six species including some less common ones in Pale Willowherb (Epilobium roseum) and Square-stalked Willowherb (Epilobium tetragonum). I’ve also been somewhat suprised to see just how abundant American Willowherb (Epilobium ciliatum) is but honestly, I’ve probably been ignoring it until now.

Notable sites

Another thing I’ve been keeping a close eye on as part of the project in the overall botanical diversity of specific squares – hopefully to create some sort of heat map when the time comes. Doing this is helping paint a clearer picture of Newcastle’s botanical hotspots, in my head atleast.

In many cases, the results of this have been unsurprising and those squares featuring a mix of relic natural or at least semi-natural habitats have come out on top. Jesmond Dene (193 species), the lower Ousburn (213 species) and Walker Riverside (171 species) are clearly rather diverse. Green spaces aside however, there have also been suprises here too. Not least the 183 species recorded in an unassuming patch of Heaton where terraced gardens provide a haven for weeds of all sorts and the square surrounding St. James’ Park stadium (193 species) where neglected building sites are rather floristically diverse. Tracking this, I definitely feel I am getting to grips with the different urban ‘microhabitats’ that matter for our plants.

Following Other’s Footsteps

Botanical recording in the city has been patchy over the years and Newcastle has only been selectively surveyed. Nathaniel John Winch was the first to begin truly mapping the flora here and many interesting records made within the city limits feature in his Flora of Northumberland Durham, 1831. In 1868, A New Flora of Northumberland and Durham, authored by John Gilbert Baker and George Tate, paid much greater heed to the neophyte flora that so often define our urban spaces, though mention of the Newcastle area is lacking.

George Swan went much further while preparing his the Flora of Northumberland (1993). Since then, however, most records have come from a few familiar names: from John Durkin, who incidentally has contributed immensely to the current project, Quentin Groom, Gordon Young etc. It is the records made by the latter recorders that I’ve been digging into recently – checking to see if the interesting plants noted 10-20 years back are still present. In several cases, they are!

I was excited to note Groom’s Common Blue Sow-thistle (Cicerbita macrophylla) at Jesmond Vale and Young’s Fragrant Agrimony (Agrimonia procera) at Scotswood. The list goes on and following in the footsteps of these recorders is helping develop a firmer pictures of our urban flora. It is also to see what has persisted and what has vanished.

More to do

Starting out, I think I had naively assumed that copiling a flora for a lone city – a relatively small geographial area – would be an easy task. I was wrong! There is just so much still to explore and plenty of rabbit holes still to venture down – duckweeds, sedges, hunting hybrid oaks. Add to this variation in flowering times, the human tendency to miss things first time around, and the need to learn new groups and I can see I’ll be busy for quite some time. Still, I’ve made a good start…

Fitting this in around a full-time job means I’ll likely run into 2025 before I can produce anything near complete. Still, better to do it right. Hopefully, when the time comes, I’ll be able to attract enough support to publish something in hard copy but we’ll cross that bridge when we come to it! Something similar to this would be nice – we’ll see if an ‘Urban Flora of Newcastle’ makes it to fruition!

Exploring Alien Plants in Newcastle

A short round-up of an excellent few days spent recording alien plants in Newcastle.

Last weekend was a busy one on the botanical front. On Saturday, alongside members of the Northumberland Botany Group, I spend a good few hours rummaging around Jesmond Dene and on Sunday, another urban flora square found Matt and I botanising the banks of the Tyne at Elswick. Both trips yielded a range of interesting sightings and of course, a great many fascinating alien plants.

Jesmond Dene

Jesmond Dene first and aside from a whole host of interesting ferns, our walk was dominated by exotics. Starting out, a quick look at spring bulbs proved productive with three species of crocus: Early Crocus (Crocus tommasinianus), Yellow Crocus (Crocus x luteus), and Spring Crocus (Crocus neapolitanus), by far the commest urban species. It was nice too to note a single Greater Snowdrop (Galanthus elwesii) too.

Nearby, the more established aliens were on full show. Milling around near Pet’s Corner, we noted Wilson’s Honeysuckle (Lonicera nitida), Himalayan Honeysuckle (Leycesteria formosa), and Salmonberry (Rubus spectabilis) and by the Ouseburn, the first leaves of Abrahem-Isaac-and-Jacobs (Trachystemon orientalis) were just starting to emerge.

Further into the dene, a far larger patch of Abrahem-Isaacs-and-Jacobs was in full flower and we were surprised to find both Bear’s-breeches (Acanthus mollis) and a large patch of Italian Lords-and-Ladies (Arum italicum) by the Ouseburn. A lone patch of Kidney-saxifrage (Saxifraga hirsuta) draped across the riverside stones by the stepping stones was also looking lovely. Add to this Winter Heliotrope (Petasites pyrenaicus) and some introduced Wood-spurge (Euphorbia amygdaloides subsp. robbiae) showing signs of absconding and there was certainly lots to see.

The Victorians and later, successive generations of park managers have displayed a tendency to plant random things in the dene. This is starkly apparent in the trees present – Wellingtonia (Sequoiadendron giganteum) to name but one – but also in the shrub layer. Looking closer at a few of these, we noted Sweet Box (Sarcococca confusa), Yellow Azalea (Rhododendron luteum), and a new one for me in American Holly (Ilex opaca).

Jesmond Dene is an odd place but an interesting one from an urban botanist’s point of view.

Elswick Riverside

Fast forward to Sunday now and keen to keep progressing with the ongoing and slightly daunting Urban Flora of Newcastle, Matt and I headed for Elswick for a potter along the riverbanks there.

Now, there were a few interesting native species to be seen here – Cut-leaved Dead-nettle (Lamium hybridum) was certainly welcome and Wild Celery (Apium graveolens) isn’t common in the city. Despite this, however, it was the aliens that drew attention. Mere minutes after leaving the car, we were greeted by a huge patch of Stinking Helleborine (Helleborus foetidus) growing in the riverside walls and further upstream, a surprise in Spurge-laurel (Daphne laureola) in full bloom.

Many of the shrubs growing in the walls here have clearly escaped the confines of the nearby industrial estate. Ignoring any that seemed planted, we recorded Laurustinus (Viburnum tinus) and more notably, Chinese Barberry (Berberis julianae) growing seemingly wild. There was even an Oleaster in there too but alas, I struggle with those.

Of course, when speaking of absconding shrubs, you cannot help but touch on cotoneasters. Here, there were a good 6-7 species growing in close proximity. Among these, some like Wall Cotoneaster (Cotoneaster horozontalis), Willow-leaved Cotoneaster (Cotoneaster salicifolius) and Waterer’s Cotoneaster (Cotoneaster x watereri) are commonplace in Newcastle. Others, however, were more noteworthy. Here too there was Swedish Cotoneaster (Cotoneaster x suecicus), Small-leaved Cotoneaster (Cotoneaster microphyllus) and Late Cotoneaster (Cotoneaster lacteus) at what seems to be only its second local site.

All in all an interesting few days and a handful of urban flora ticks to boot…

Getting to Grips with Spring Bulbs

Last weekend, I decided to take a closer look at wild and naturalised spring bulbs. From snowdrops to crocuses, here are a few spotted on recent walks.

Daffodils, crocuses and of course, snowdrops are some of our most iconic and beautiful spring flowers. Despite this, they can be a tricky bunch to tell apart with a great many species out there and in the case of the daffodils, many confusing and largely similar cultivars. Recording for the Urban Flora, this spring, I’ve made it my mission to learn the most abundant species and varieties growing in my local area. It will take a while, for sure, but a few initial discoveries are shared below.

Crocuses

I’ve always assumed that crocuses would be a difficult bunch to learn. I’m not sure why. That said, there doesn’t appear to be as much diversity locally as I had assumed the commonest naturalised (and dumped) varieties inevitably turn out to be one of the three below. This website is a great help when identifying them.

Early Crocus (Crocus tommasinianus)

With its vivid, lilac petals and tendency to bloom in great drifts, Early Crocus is a lovely little plant. Introduced from South-East Europe, this species is commonly planted in parks and churchyards. It readily naturalises and can form large colonises where conditions are right, as seen below on the approach to Jesmond Dene.

Early Crocus is told apart from the rest by its pale lilac-coloured petals, white petal tube and narrow leaves.

Spring Crocus (Crocus neapolitanus)

Spring Crocus is a burly plant and comes in a host of colours. It is the species most likely to be planted in gardens and along roadsides and for this reason, is often the one that makes its way into the wild via waste or deliberate introductions. A native of Southern Europe, it was only recently split from White Crocus (Crocus vernus) which I am yet to see locally.

This one can be identified by the purple petal tube at the base of the flower and its large size. Looking closer, you’ll also notice that its branched stigma is longer than the three stamens that surround it. In White Crocus, this is noticeably shorter.

Yellow Crocus (Crocus x luteus)

A garden hybrid, Yellow Crocus is very popular in cultivation and is often planted in gardens, parks and areas of community planting. It will persist in the wild from garden throw-out but can also be found as an introduced plant in a variety of habitats. Those below were spotted on a parkland bank and urban playing field.

Yellow Crocus has vibrant, golden-yellow petals with a variable amount of brown smudging on the exterior. Usually, this is less prominent than in Golden Crocus (Crocus chrysanthus) but not always and the only surefire way to separate them is to look at the corm. In Yellow Crocus, this divides vertically.

Snowdrops

Ah, snowdrops. Cheery, abundant and altogether lovely, they are surely one of our best spring flowers. They are also pretty diverse with several species, hybrids and cultivars likely to pop up in urban areas where they have been dumped or introduced. Some of these varieties are easier to separate than others and I’ve managed to find a few in the local area. The BSBI key to snowdrops is a great place to start.

Greater Snowdrop (Galanthus elwesii)

A hulking plant, noticeably larger than our Common Snowdrop (Galanthus nivalis) Greater Snowdrop has its roots in the Caucuses. It is frequently planted in parks, churchyards, large gardens and amenity land and may occasionally spread where conditions allow. Such was the case in the lovely Northumbrian cemetery below.

This species has extremely broad leaves which are both glaucous and hooded at the tip. The markings on the inner petals of the flower are striking and usually take the form of a dark-green ‘x’ shape as seen below. The flowers can vary, however, and if you have something different, you may have a distinct form or cultivar.

Galanthus x hybridus (Galanthus elwesii x plicatus)

While admiring the Greater Snowdrops in the aforementioned cemetery, there were also many plants present which displayed the features of Pleated Snowdrop (Galanthus plicatus). I had assumed they were just that until some help from Alex Prendergast on Twitter revealed they were likely the hybrid between these two species, Galanthus x hybridus.

As you might expect, the hybrid is intermediate between the parents with somewhat pleated leaves with hooded tips. I’ll know next time!

Green Snowdrop (Galanthus woronowii)

A far nice snowdrop to contend with is the Green Snowdrop. Introduced occasionally to gardens and greenspaces and occasionally escaping, this is another large and impressive species. Thankfully, it lives up to its name in having bright grass-green leaves which contrast with the glaucous foliage of other species. You need to consider Galanthus ikariae too but this does seem to be the more common of the two.

Snowdrop (Galanthus nivalis)

Ah, finally, the Common Snowdrop. With their thin leaves and altogether delicate appearance, this is the snowdrop you’re most likely to find just about anywhere, from woodlands to parks. What is interesting about these, however, is that there are several distinct forms to watch for too.

Commonly occurring within large populations of Common Snowdrop or as a deliberate introduction in itself, the double-flowered variety (Galanthus nivalis f. pleniflorus) has stacks of additional petals and is a brute in comparison to the usual sort.

You’re not likely to encounter it outside of several known sites but included here out of sheer excitement, a yellow form of Common Snowdrop is also known up North. Known as Galanthus nivalis Sandersii Group, this Northumbrian speciality exhibits yellow as opposed to green markings and has leaves which are noticeably paler. It is a real beauty.

Daffodils

Beyond the native Wild Daffodil (Narcissus pseudonarcissus subsp. pseudonarcissus) I’m dreadful at daffodils. The great big lurid ones that frequently escape from cultivation especially. With hundreds of cultivars and a few species too, there are certainly lots out there to be discovered and feel inspired by Mick Crawley’s superb key, I wanted to take a look at some of those in the local area. Spoiler: I got them wrong but thankfully, Mick is extremely helpful on social media. I’ve only managed to find one so far…

Narcissus ‘Rijnveld’s Early Sensation

One of the hideously complicated ‘big yellow daffodils’ Narcissus ‘Rijnveld’s Early Sensation‘ is usually, according to Mick Crawley, the first cultivar to bloom each year. In the South, this can be as early as January. Up here, we have an entirely different climate and this cultivar is most likely to be spotted from mid-February it would seem.

With flower stems around 40cm tall, a flanged (I like that word) trumpet and slightly overlapping petals, it is a rather nice daffodil.
