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.

Cut-leaved Dead-nettle (*Lamium hybridum*)

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.

Early Dog-violet (Viola reichenbachiana)

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.

Identifying Yellow Composite Flowers

Get started identifying a range of widespread yellow composites with a new simplified crib

Thank you all so much for continuing to read and download recent entries in this series of accessible plant cribs. They are evolving overtime and it is great to hear your feedback!

After tackling willowherbs, I wanted to try something different base the next of these cribs on your feedback. Shock horror, it turns out the two groups you want to see tackled are yellow composites and grasses. I may need a stiff drink before turning my attention to the latter, but we can certainly give the flowers a go!

Now, most of us are familiar with the Dandelions that brighten up grassy areas with their yellow flowers come spring and summer. In many cases, however, a plant which looks like a Dandelion may not actually be so. Instead, there are several superfisically similar plants – the hawkbits, hawk’s-beards, cat’s-ears and sow-thistles – that share a similar look. Each of these shares the familiar yellow flower head making it necessary to examine other parts of the plant. Most notably, the leaves, phyllaries and often, the stem.

Another excellent resource, created by the Norfolk Flora Group, is also worth a look and can be found here.

Identifying Yellow Composites

Yellow composites are a diverse and slightly daunting group. Here, we’ll aim to cover the species botanists are most likely to encounter while out and about in the North East though the information shared should apply equally well elsewhere in the UK. This crib addresses the following species:

Lesser Hawkbit
Rough Hawkbit
Autumn Hawkbit
Smooth Hawk’s-beard
Beaked Hawk’s-beard
Rough Hawk’s-beard
Mouse-ear Hawkweed
Smooth Sow-thistle
Prickly Sow-thistle
Perennial Sow-thistle

On the trail of Northumbrian Snowdrops

It’s no secret that I’m a big fan of snowdrops. These delicate flowers, signaling the arrival of spring, have become an obsession of mine in recent years. So much so that I spend a lot of my free time exploring the Northumbrian countryside, looking for new varieties, and browsing the internet for more options to add to our tiny yarden – much to Matt’s annoyance!

Although February is winding down and the peak snowdrop season is almost over, there are still plenty to be found in different parts of my home county. In this week’s blog post, I’ll share some of the snowdrops I’ve spotted recently on jaunts around the county. Let’s start with a new discovery for me – a snowdrop I stumbled upon while walking through rough terrain in Monkseaton last week. With it’s pleated green leaves with a distinct glaucous central band, and after some research, it seems to be the Pleated Snowdrop (Galanthus plicatus), a species not often encountered in these parts, at least according maps held by the BSBI.

Also known as the Crimean Snowdrop, this species is indigeonous to Türkiye, Romania, and Crimea and is thought to have been brought to the UK by British soldiers fighting in the 1850s Crimean war. It is widely grown in gardens but far less common in a wild state than the plentiful Common Snowdrop (Galanthus nivalis).

Rural Churchyards

Churchyards are great places to find snowdrops, as they’re often planted in large numbers and left to spread naturally. Some of the best spots I know locally are in churchyards, and they often have surprises in store. After a meeting with our wedding venue a couple of weeks ago, Matt and I visited two such sites in quick succession, specifically to look for a local specialty: yellow snowdrops, also known as Galanthus nivalis ‘Sandersii Group’.

These yellow snowdrops occur naturally, though not abundantly, within populations of Common Snowdrop in parts of Northumberland. They’re named after James Sanders, who first identified them at Chillingham. While they’re not as common nowadays due to enthusiasts collecting them, they can still be found if you know where to look.

During our visit, we managed to find a few isolated patches of them, alongside plenty of the double-flowered variant of Common Snowdrops, Galanthus nivalis ‘Flore Pleno’. It was a successful trip!

Fast forward to last weekend, and once again, I found myself exploring another remarkable churchyard, this time as part of a course I’m leading for the Natural History Society of Northumbria. This site proved to be quite fascinating, yielding more of the exquisite Sandersii snowdrops along with two interesting snowdrop hybrids: Galanthus x hybridus, a cross between Pleated and Giant Snowdrops (Galanthus elwesii), and Galanthus x valentini, a hybrid of Common and Pleated Snowdrops.

Interestingly, despite our thorough search, we completely failed to find any pure Pleated Snowdrops in the entire cemetery. It left us pondering whether they had bred out of existence in this particular location. Nonetheless, we were treated to large patches of pure Greater Snowdrops, characterised by their broad, glaucous leaves and the variable green markings on their flowers.

Howick Hall Gardens

Howick Hall Gardens has become a go-to destination for my Sunday strolls. With its expansive grounds and rich history, it’s especially charming during “snowdrop season.” The dedicated Snowdrop Trail they offer is definitely worth checking out.

While the gardens may not feature a wide variety of snowdrop species, the sheer number of Common Snowdrops blanketing the woodland is quite remarkable. There are millions of them scattered throughout, creating a breath-taking sight.

Of course, it wasn’t just snowdrops in flower at Howick and fabulous scones aside, we also enjoyed the sight of several crocus species, well naturalised at this point, our first Buff-tailed Bumblebee (Bombus terrestris) of the year and even

And there we have it, a hopefully not too tedious account of a wonderful few weeks spent hunting for these endearing little flowers. To finish on a high, I should say that another snowdrop species, the Green Snowdrop (Galanthus woronowii) is once again flowering in a handful of wilder spaces close to home in Newcastle. A favourite of mine, I am ashamed to admit that I completely forgot to take photos. Instead, you’ll need to make do with this one from 2022.

10 Great Places to Enjoy Wildflowers in Northumberland

Northumberland, my home county, is a haven for botanists, offering a rich tapestry of landscapes that range from windswept hills and expansive moors to coastal dunes, wetlands, and impressive woodlands. As a lifelong resident, I may be a tad biased, but the flora here truly spoils enthusiasts for choice.

To help inspire your next stroll in nature, I thought I’d share a curated list of ten great places to enjoy wildflowers in Northumberland. While some may be familiar, a couple might just surprise you, hopefully adding an extra layer of discovery to your next botanical adventure.

As a quick disclaimer, I should add now that list is not exhaustive. There are many other great places out there to be explored…

1: The Snook, Holy Island

Lindisfarne, a part-time island off the North Northumberland coast, needs little introduction. Revered for its religious significance, rich history, and breathtaking scenery, the island is undoubtedly Northumberland’s premier botanical hotspot, offering an abundance that exceeds the scope of a single visit.

Among Lindisfarne’s diverse habitats, ‘The Snook’ stands out with its slacks, grey dunes, and saltmarsh. This peninsula, distinguished by a solitary house famous for its role in the ITV series Vera, is home to botanical treasures too numerous to detail here.

For orchid enthusiasts, early summer unveils a spectacular display of Common Spotted Orchid, Early and Northern Marsh Orchids, alongside various hybrids, Common Twayblade, and a profusion of Marsh Helleborine. Recently demoted to a sub-species but still rather species, drier spots also hold populations of Lindisfarne Helleborine – once thought of as a Northumbrian endemic.

Beyond orchids, The Snook boasts exceptional diversity. Highlights include the rare Seaside Centaury, the delicate Bog Pimpernel, and Scots Lovage, teetering on the southern edge of its range in Northumberland. Brookweed, an unassuming yet notable plant, thrives here, alongside Autumn Gentian and smaller wonders like Lesser Clubmoss, Variegated Horsetail, and Black Bog-rush (okay, these aren’t wildflowers but they are interesting!).

While visiting the Snook, you may also like to pop into the nearby dunes where species like Pyramidal Orchid, Bee Orchid, Blue Fleabane and Viper’s-bugloss also await.

Lindisfarne Helleborine (*Epipactis sancta*)

2: East Chevington Nature Reserve

East Chevington, a Northumberland Wildlife Trust reserve perched atop a former mine overlooking scenic Druridge Bay, is well worth a visit. Featuring expansive wetlands, reedbeds, dunes, and grassland, the site is a haven not only for more obvious wildlife but also for a diverse array of plants which we’ll explore here.

As one of the rare pockets of high-quality coastal grassland in South Northumberland, the reserve has an intriguing flora. Standouts include Lesser Butterfly-orchid, Dyer’s Greenweed, Pyramidal Orchid, not to mention Marsh Helleborine and Sea Bindweed, rediscovered at the site in 2023. And, of course, one can’t easily overlook expanses of Bloody Crane’s-bill, Northumberland’s county flower, adorning pathsides and grassy areas.

Beyond the more prominent blooms, attentive visitors will be rewarded with sightings of Zigzag Clover, Fairy Flax, Celery-leaved Buttercup, Long-headed Poppy, and a myriad other plants. For an extra treat, a brief detour to the nearby beach unveils the hardy coastal flora of the county, featuring Prickly Saltwort and other specialists like Sea-rocket and Sea Sandwort.

Accessible to all, like many Wildlife Trust reserves, East Chevington invites exploration.

Celery-leaved Buttercup (*Ranunculus sceleratus*)

3: Warkworth, dunes and saltmarsh

The town of Warkworth, nestled close to Amble on the Northumberland coast, is picturesque in its own right. However, the nearby dunes, saltmarsh and coastal grasslands, somewhat overlooked compared to more famous sites like Holy Island, possess much more to be admired.

In late spring, the dune slacks come alive with the countless flowering spikes of the Early Purple-orchid and as summer unfolds, visitors can delight in another local specialty, Maiden Pink, as its diminutive flowers peek out amidst a tapestry of interesting, albeit less vibrant, grasses and sedges.

A close inspection of the sward at Warkworth reveals a miniature world with species like Little Mouse-ear, Mouse-ear Hawkweed, Common Stork’s-bill, and an assortment of delicate eyebrights. Yet, larger blooms are equally abundant. Keep an eye out for Viper’s-bugloss, the frothy flowers of Hoary Cress, and treats like Wild Basil and Burnet Rose.

The strandline and saltmarsh at Warkworth add another layer of interest with a rich community of salt-loving plants. Among these, Sea Sandwort, Sea Purslane, Spear-leaved Orache, and the ever-charming Thrift. Undoubtedly, Warkworth is a special place and there undoubtedly new species to be found.

Maidan Pink (*Dianthus deltoides*) at Warkworth

4: Embleton Quarry Nature Reserve

Embleton Quarry Nature Reserve, a hidden gem often overshadowed by more well-known sites on this list, boasts a quiet charm. Managed with dedication by local volunteers, this small but tranquil reserve has much to offer visiting botanists.

Orchids take center stage at Embleton (don’t they always?) and are represented by Common Spotted, Northern Marsh, and, notably, Bee Orchid. Beyond these fan favorites, the site stands out for harboring populations of Purple Ramping-fumitory and White Ramping-fumitory, alongside a cheery array of familiar species such as Wild Teasel, Red Bartsia, Salad Burnet, and Weld.

Much of Embleton’s interest lies its close proximity to residential areas, responsible for introducing a mix of garden escapes. While none have become invasive, the reserve hosts several botanical oddities like Lamb’s-ear, Garden Peony, Poet’s Daffodil, and Hidcote Comfrey, among a plethora of other aliens.

For those with a penchant for exploration, a visit to the nearby Embleton Churchyard unveils another fascinating plant — Deadly Nightshade, thriving as one of its only Northumberland strongholds.

5: Newbiggin-by-the-Sea

Newbiggin and its surrounds stand out as an ecologically rich area that might just surprise visitors. A northward walk from Church Point reveals a varied landscape encompassing sandy shoreline, relic dunes, and the rough grassland of the golf course. Here, several notable wildflower species can be found including the diminutive Bird’s-foot, a member of the pea family, the coastal specialist Purple Milk-vetch, and just occasionally, Bee Orchids. The Church Point car park itself is noteworthy, teeming with Hoary-cress, Thrift, Dwarf Mallow, and other interesting plants.

Exploring the sandy shoreline may yield four species of Orache, among them Frosted Orache and Babbington’s Orache. Additionally, common coastal plants such as Buck’s-horn Plantain and Sea Milkwort are abundant. Heading higher up, the cliffs offer Sea Campion, while the golf course holds rarer species such as Good-King-Henry, Northern Marsh-orchid, Burnet Rose, and Pencilled Crane’s-bill — a notable escapee at the site.

Purple Milk-vetch (*Astragalus danicus*)

6: Allen Banks and Staward Gorge

Managed by the National Trust, Allen Banks boasts a distinctive blend of ancient woodland and ornamental planting, reflecting the influence of the past custodians on the estate. Renowned as one of the premier locations in Northumberland to investigate our ancient woodland flora, the site offers much of interest with highlights of Bird’s-nest Orchid, Early-purple Orchid, and the peculiar-looking Toothwort.

A stroll along the wooded banks of the Allen introduces visitors to other indicators of ancient woodland, including Goldilock’s Buttercup, Bitter Vetch, Wood Crane’s-bill, and Great Horsetail. The presence of Calaminarian Grassland, characterised by its soil polluted with industrial metals, adds another layer of interest. In this area, delicate Mountain Pansies flourish.

For those seeking a longer walk, a well-signposted trail to Morralee Tarn is recommended. Once a Victorian boating lake, it has transformed into a rich wetland habitat. Timing your visit right may reward you with sightings of White Water-lily, Mare’s-tail, and the intriguing Marsh Cinquefoil.

7: Letah Wood, Hexham

Letah Wood, believed to be Northumberland’s last surviving ‘Daffodil wood,’ offers a spectacular display with its abundant Wild Daffodils blanketing the woodland floor each spring.

Beyond the captivating display of Daffodils, the wood boasts a rich diversity of woodland wildflowers. Visitors can expect to encounter Giant Bellflower, Wood Anemone, Pignut, Lords-and-Ladies and the iconic English Bluebell. A special highlight for those exploring the woodland is the much rarer Herb-paris.

Additionally, Letah Wood is a haven for those interesting in trees, ferns and bryophytes. While these aspects are beyond the scope of this post, they contribute to the overall richness of the wood.

Wild Daffodiils (*Narcissus pseudonarcissus subsp. pseudonarcissus*) at Letah Wood

8: Hen Hole, College Valley

The Hen Hole stands out as arguably the most spectacular gorge in Northumberland, and earns its place as one of the county’s top botanical sites. While its remoteness may pose a challenge, the awe-inspiring scenery and diverse flora make it well worth the effort. Before embarking on the journey, be sure to pack sturdy walking boots and ample snacks for the hike that awaits!

Hen Hole has been visited by many notable botanists over the years, from Baker & Tate to George Swan, and is celebrated for its rare arctic-alpine plants, including Alpine Saw-wort and Roseroot. While these flowers are elusive, the journey toward the gorge from Mounthooley offers more obvious specialities such as Alpine Willowherb, Pale Forget-me-not, Starry Saxifrage, and Butterwort. Be sure to stick close to the College Burn – most of the more interesting plants seldom grow far from water.

The more abundant flora of Hen Hole includes familiar species like Heath Bedstraw, Goldenrod, Heath Spotted-orchid, Wild Thyme, and Wood Crane’s-bill. Beyond those, however, the gorge treats visitors to superb views, scenic waterfalls, and a plethora of other wildlife, ensuring that the journey is rewarding in any season.

9: Cullernose Point, Howick

Cullernose Point, located between Craster and Howick, is a relatively small but ecologically significant coastal site. As part of the Northumberland Coast Path, it provides easy access for visitors interested in exploring its clifftop grasslands, which boast noteworthy populations of Purple Milk-vetch and Spring Squill – a charming little bulb with bright blue, starry flowers.

Beyond these botanical highlights, the clifftop grasslands support additional plants including Sea Mouse-ear, Thrift, Wild Thyme, Heath Milkwort, Heath Groundsel, and other flora characteristic of coastal environments.

The small size of this site mean it is often better suited as a pitstop, perhaps on route to more floriferous sites further North?

10: Scotch Gill Wood, Morpeth

Scotch Gill Wood, situated just outside the market town of Morpeth, stands out as a prime example of semi-natural ancient woodland. Notably, this woodland offers a much more accessible destination for those interested in exploring our woodland flora.

The wood is home to a variety of plant species characteristic of older woodlands. Careful exploration might reveal Toothwort, Goldilocks Buttercup, Spurge-laurel, Yellow Star-of-Bethlehem, and the intriguing Mochstatel, among others.

In addition to the vibrant species listed above, Scotch Gill Wood hosts several less colorful but equally interesting plants, notably the Rough Horsetail. Damp areas within the wood add another layer of botanical interest with the occurrence of Hemlock Water-dropwort, Brooklime, and Large Bittercress.

The accessibility of Scotch Gill Wood makes it an ideal destination for those seeking a woodland walk without venturing too far from civilisation.

Yellow Star-of-Bethlehem (*Gagea lutea*)

Urban Flora of Newcastle – Musing over maps

Urban Flora of Newcastle – Coming 9 March 26

The Urban Flora of Newcastle and North Tyneside is the first comprehensive account of the wild plants growing across the Newcastle and North Tyneside conurbation, one of the largest in the UK.

Based on six years of fieldwork, the book documents more than 1,120 native and naturalised plants -around a third of Britain’s entire flora.

Find out more

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.

After tackling forget-me-nots, now seemed like a good time to produce another simplified crib on an equally appealling group of plants – our pesky willowherbs.

Members of the evening-primrose family, Onagraceae, willowherbs are familiar flowers of our urban spaces. While they occur in all habitats, they are particularly prominent in human-influenced landscapes where around eight species can commonly be encountered in pavements, waste areas and even gardens. The simplified key below covers those most likely to be encountered in the North East but please note, there are several rarer ones out there.

Key factors to focus on when identifying willowherbs include the shape of the stigma, hairiness and importantly, the type of hairs present, and stem/petiole features.

Identifying Willowherbs

Willowherbs are a rather diverse bunch. Here, we’ll aim to cover the species botanists are most likely to encounter while out and about locally; though the information shared should apply equally well elsewhere in the UK. This crib addresses the following species:

Great Willowherb
Hoary Willowherb
Broad-leaved Willowherb
Square-stalked Willowherb
Short-fruited Willowherb
Marsh Willowherb
American Willowherb
Pale Willowherb

Additionally, and more for curiosity than anything else, some information is also included on various willowherb hybrids found across the UK.

New Year Plant Hunt: What’s flowering this winter?

I love the BSBI New Year Plant Hunt. Each year, this nifty citizen science project provides the perfect reason to head outside, brave the winter air, and find some interesting plants – not something I would have considered just a few years ago! Better still, the project is providing some valuable data about how our wild and naturalised plants are responding to a changing climate. A win win, really!

With only a few days of the holiday left, I confess I have gone a little crackers this year when it comes to the New Year Plant Hunt, with fourwalks in different corners of the local area. A nice way to burn off those Christmas calories perhaps?

Tynemouth

On Saturday morning, the first session of my new ‘Botanist’s Year’ course provided the perfect excuse for some group plant hunting. Meeting attendees at Tynemouth, we set about recording flowering plants growing in sea defences, coastal grassland, priory walls and nearby streets. Cutting a long story short, there wasn’t overly much to see with just 21 species noted in bloom. That said, some of these were rather nice with a good showing of Common Snowdrop (Galanthus nivalis), ample Alexanders (Smyrnium olusatrum) and even a solitary example of Fool’s-parsley (Aethusa cynapium) – I am not sure I have ever seen that one flowering in winter.

Of course, the reliable winter-blooms featured in our total too: Daisy (Bellis perennis), Annual Meadow-grass (Poa annua), Red Dead-nettle (Lamium purpureum) and Ragwort (Jacobaea vulgaris) to name but a few. The group also encountered a stray Garden Pansy (Viola x wittrockiana) in a pavement crack – a surprisingly common occurence.

No visit to Tynemouth would be complete without a moment of appreciation for the copious amount of Wild Cabbage (Brassica oleracea) which grows on site as a relict of cultivation by local monks. They weren’t in flower on this occasion, mind you.

Heaton

For the last four years Matt and I have carried out an annual New Year Plant Hunt on the streets of Heaton, close to home. While being awful good fun, this has also allowed us to gain a good idea of localised changes in the flowering times of several species. Suffice to say, 2023 seems to be a bit of a poor year and in three hours, we recorded just 31 species compared to the 50+ of 2022. Perhaps it was was a touch of frost, or even over-zealous weeders?

The usual supects mentioned previous all featured in our Heaton hunt and by large, most of the plants found were ones you would expect to see in winter. Neophytes (human introductions) in Trailing Bellflower (Campanula poscharskyana), Adria Bellflower (Campanula portenschlagiana) and Yellow Corydalis (Pseudofumaria lutea) that seem to flower year-round and typical winter wildflowers in Common Whitlowgrass (Erophila verna) and White Dead-nettle (Lamium album). It was, however, interesting to note several grasses still in flower with sightings of Water Bent (Polypogon viridis), False Oat-grass (Arrhenatherum elatius) and Wall Barley (Hordeum murinum). I wonder what next year will bring?

Scotswood

The most botanically interesting hunt of the week now and a new route for Matt and I at Scotswood. Scotswood Road and its associated grassland, scrub and industrial plots is usually rather interesting and in total, we chalked up 31 flowering plants during our yomp. The ‘common ones’ featured heavily again with examples in Gorse (Ulex europeaus) and Feverfew (Tanacetum parthenium) but there were surprises also. On a particularly nice stretch of verge, we found both Field (Knautia arvensis) and Small Scabious (Scabiosa columbaria) in flower alongside Musk-mallow (Malva moschata). Quite a nice display for winter! Elsewhere, we noted Narrow-leaved Ragwort (Senecio inaequidens) and Smooth Hawk’s-beard (Crepis capillaris) while Common Vetch (Vicia sativa) featured surprisingly frequently.

For once, it was actually the non-flowering plants that proved most interesting at Scotswood. Having sadly lost many of them to the mower in spring, it was fabulous to note well over 200 Bee Orchid (Ophrys apifera) rosettes on nearby areas of amenity grassland and some recent roadworks provided a sighting of Parsley-piert (Aphanes arvensis), an entirely new one for the urban flora!

Ouseburn

New Year’s Day now and the last New Year Plant Hunt organised through the Natural History Society of Northumbria. Setting off to explore the streets of Heaton and later, taking a detour to the Ouseburn Valley, we were thrilled to find 35 species of wild and naturalised plant in flower. Better still, the sun was shining – a rare thing of late!

Once again, the usual suspects were out in force but what was more interesting was the abundance of typically ruderal/arable plants blooming in forgotten corners and neglected planters. As a group, we were particularly excited to find Small Nettle (Urtica urens) and Green-field Speedwell (Veronica agrestis), followed closely by Ribbed Melilot (Melilotus officinalis), Cut-leaved Dead-nettle (Lamium hybridum) and Small-flowered Crane’s-bill (Geranium pusillum). Down by the Ouseburn, the first Snowdrops (Galanthus nivalis) of the year had emerged too. Always nice to see…

All in all, a lovely way to spend New Year’s Day and a great way to round off a busy week jampacked with plants!

Identifying Forget-me-nots

Get started identifying the widespread forget-me-nots you’re most likely encounter in a new, simplified crib

Thank you all so much for continuing to read and download recent entries in this series of accessible plant cribs. They are evolving overtime and it is great to hear your feedback.

After tackling crocuses, now seemed like a good time to produce another simplified crib on an equally appealling group of plants – our forget-me-nots.

Members of the Borage family, Forget-me-nots are familiar flowers of spring and popular for their bright blue blooms. They occur in all habitats, from urban pavements to pool-sides and upland flushes and at times, are popular as garden plants. They simplified key below covers those most likely to be encountered in the North East but please note, there are several rarer ones out there.

Key factors to focus on when identifying forget-me-nots include flower colour, style length, pedicel length and of course, the structure and arrangement of hairs.

Identifying Forget-me-nots

Forget-me-nots are not extraordinarily diverse, at least in North East England. Here, we’ll aim to cover the species botanists are most likely to encounter while out and about locally; though the information shared should apply equally well elsewhere in the UK. This crib addresses the following species:

Field Forget-me-not
Wood Forget-me-not
Changing Forget-me-not
Early Forget-me-not
Tufted Forget-me-not
Creeping Forget-me-not
Pale Forget-me-not

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.

Water Bent (*Polypogon viridis*) © Rutger Barendse

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 Encounter with Lady Clermont’s Spleenwort (Asplenium x clermontiae)

A quick account of an overdue run-in with a Northumbrian speciality – Asplenium x clermontiae

Now, I am rather dreadful at ferns and for a while now have been trying to improve by tracking down our region’s scarcer species. Top of that list for quite a while has been Lady Clermont’s Spleenwort (Asplenium x clermontiae), a hybrid between Wall-rue (Asplenium ruta-muraria) and Maidenhair Spleenwort (Asplenium trichomanes).

Now, this is a rather special fern. Despite its parents being rather widespread and growing together on walls and structures across the UK, it is only known from three sites nationally and only as individual plants. This means that population of this unassuming little plant stands at three individuals nationally, just maybe with a few more out there to be discovered.

Of the sites where Asplenium x clermontiae is known, it is a site in North Northumberland (VC68) that is perhaps the most studied. Indeed, after it was first identified in 2000 by George Swan, it was recorded 20 or so times until 2012 and visited by many more botanists keen to see it. Interestingly, local records held by the BSBI stopped post-2012 though it was reported by Stewart Sexton in this blog post. All of this means that this single little fern hasn’t been reported in almost a decade. Had it gone or was it simply being kept quiet? Today, I went north once again to try and find out, and this time, it appears I was successful!

This was my third attempt at looking for this plant in truth, but I won’t begrudge myself too much – finding a single rare fern among a sea of commoner species is actually quite a challenge. Still, I am glad to finally lay eyes on what is perhaps the scarcest plant I have encountered anywhere in Britain to date. Never a dull day, eh?

Identifying Crocuses

Get started identifying the naturalised crocuses you’re most likely encounter in a new, simplified crib.

Thank you all so much for continuing to read and download recent entries in this series of beginner’s plant cribs. They are evolving overtime and it is great to hear your feedback.

After tackling snowdrops, now seemed like a good time to produce another simplified crib on an equally appealing group of spring plants: our Crocuses.

Members of the Iris family, crocuses are extremely popular in cultivation owing to their early flowering and vibrant colours. This popularity means that they are a familiar sight in churchyards, parks and amenity areas across the UK. From time to time, several may also turn up in more natural settings as a result of garden discards or dumped horticultural waste.

Key factors to focus on when identifying crocuses include flower colour, colour of the petal tube, leaf width, and length of the reproductive parts. In some, you’ll also need to scrutinise the corm – often a challenging task!

Identifying Crocuses

Owing to a long history of hybridisation, our crocuses are a diverse bunch and can come in a daunting array of colours and forms. This makes identifying some, particularly garden cultivars, somewhat challenging. Still, data from botanists across the UK shows that certain species (and hybrids) are more likely to be encountered than others. This crib addresses the following species:

White Crocus (Crocus vernus)
Spring Crocus (Crocus neapolitanus)
Early Crocus (Crocus tommasinianus)
Sieber’s Crocus (Crocus sieberi)
Snow Crocus (Crocus nivalis)
Hybrid Crocus (Crocus x hybridus)
Yellow Crocus (Crocus x luteus)
Golden Crocus (Crocus chrysanthus)
Silvery Crocus (Crocus biflorus)
