Geranium orientalitibeticum New to Britain

Nicky Vernon and Bruce Brown sent me a brilliant list of records a few weeks back for a site in the middle of nowhere, or as good as for this part of the world, up on Draughton Moor (VC64). Amongst an impressive assemblage of garden escapes one name jumped out at me - Geranium orientali-tibeticum. I did not really doubt it given the recorders, and also because it is quite a distinctive species with its yellow marbled leaves. But being a Crane's-bill fan (verging on a stamp collector when it comes to Dusky Crane's-bill Geranium phaeum and its ilk) I wanted to see more. The weather has not yet allowed me to pay homage in person, so I was very pleased today to hear Nicky and Bruce had been back and taken photographs (below).

To the best of my knowledge this species has never been recorded growing wild in Britain and Ireland (based on the BSBI Distribution Database). A slight surprise given this is a relatively well known garden plant, perhaps a little old fashioned these days, which spreads prolifically by rhizomes. The latter trait probably identifies one reason why it is less widely grown these days, and is also a possible means for its arrival at the site. Nicky notes that trees had been planted nearby so it may have come with these, or with the Montbretia (Crocosmia x crocosmiiflora), another thug, growing nearby.

And if you are wondering whether to hyphen (as commonly done) or not, this is neatly and honestly explained by Peter Yeo in his monograph on the genus. The hyphen was added by him to make it easier to read and pronounce the name, and is not strictly correct. I can see his point.

Skipton and Embsay

On Saturday I took a trip on the train out to Skipton (VC64) to start work on a couple of under-recorded hectads. I picked a circular route out to Embsay and the reservoir. It did not turn out to be the most inspiring countryside with intensive farmland in the lowland and a 'sheep-wrecked' upland edge. But needs must with the pressures of Atlas 2020 mounting, and it just means you have to look a little harder.

The first nice find was a good stand of Purple Loosestrife (Lythrum salicaria) along Springs Canal, later to be seen again at the entrance to Skipton Wood. This attractive plant does not appear to have been recorded from this hectad previously.

Lowther Lake a couple of weeks back

Walking up The Bailey I was able to look up onto the walls of Skipton Castle where there were naturalised colonies of Aubrieta (Aubrieta deltoidea) and Golden Alison (Aurinia saxatilis). The former had not been recorded here previously, and the only other record for the hectad was last century (pre-1999, details very vague as is the case for too many records). Golden Alison was new to the hectad.

After a dull walk down into Embsay things picked up again with a number of oddities along Brackenley Lane. First up was a couple of plants of Upright Spurge (Euphorbia stricta). This is a rare British native but it is a casual up here. I see it is listed by some seed suppliers as 'Golden Foam'. A nice plant but I am not sure I need to grow it my garden. Each to their own.

Old walls further along the lane had Caucasian Stonecrop (Sedum spurium) and Snow-in-summer (Cerastium tomentosum), and then this surprise by the steps up to the footpath across the fields. Yellow Oxeye (Telekia speciosa).

Emerging onto Pasture Road I found a nice stand of Dusky Crane's-bill (Geranium phaeum var. phaeum) where Embsay Beck passes under the road. Still a few flowers present despite the season.

Reaching the reservoir I couldn't wait to get down to the shore to look for drawdown flora. Unfortunately this is one of the reservoirs where this is very poorly developed and there were none of the specialities. The highlights being Tufted Forget-me-not (Myosotis laxa) and Marsh Yellow-cress (Rorippa palustris). The latter the first record for the hectad since pre-1969. I was then pleased to find a bush of Glandular Dog-rose (Rosa squarrosa), a hectad first, swiftly followed by yet another in the form of Musk (Mimulus moschatus). A single large clump was growing in the northern inflow.

Heading up onto the Moor, there was only slim pickings but it allowed me to record the usual suspects. The nicest find was Climbing Corydalis (Ceratocapnos claviculata). I then dropped down back towards Embsay. A few useful records were made on route, mainly garden escapes and plantings. The biggest surprise was Algerian Ivy (Hedera algeriensis) established in plantation behind the roadside wall. I suspect this species may be overlooked elsewhere, being passed over for Irish Ivy (Hedera hibernica Hibernica Group). Look out for large leaves, ruby red petioles and young stems, and a pine scent.

An old wall in Embsay had a nice bush of Garden Lavender (Lavandula angustifolia) growing out of it, no doubt self-seeded from a nearby garden.

Having a little time to kill before catching my train I wandered up to Skipton Woods. Not the most interesting of woods (especially at this time of year), too many feet and too much bare ground, but adding a few plants that had not been recorded previously. Including such obvious species as Branched Bur-reed (Sparganium erectum). It was also good to find the Herb-Paris (Paris quadrifolia) just about still in leaf, allowing me to collect a detailed grid reference. However justifying this brief diversion was the best find. A large plant of Indian-rhubarb (Darmera peltata) has somehow managed to establish in the bank of Eller Beck by the boardwalk. I'm not sure if this is the same plant last reported in 2004, the location details are too vague, but it seems likely.

Settle Sojourns

I've been to Settle a number of times this year, it being a handy base for recording this hectad for Atlas 2020. However, I have had little time for posting pictures so it is time for a little catch up. In no particular order ...

Virginia-creeper (Parthenocissus quinquefolia), colonising a wall on the Highway and new to the hectad

Perennial Sunflower (Helianthus x laetiflorus 'Lemon Queen'), start of Stackhouse Lane, Giggleswick. First mentioned to me by Mike Canaway

Double-flowered Feverfew (Tanacetum parthenium 'Bachelor's Buttons') at Langcliffe Mill

My second favourite, sad I know, Prickly Sowthistle (after subsp. glaucescens) Sonchus asper subsp asper var. integrifolius in Giggleswick

Boo Hiss, Garden Lady's-mantle (Alchemilla mollis) making its bid for world domination, Craven Lime Works

Hydrangea (Hydrangea macrophylla), Craven Lime Works

How many succulents can you spot? churchyard wall Langcliffe. Some answers below

Hen-and-chicks (Jovibarba heuffelii)

Oregon Stonecrop (Sedum oreganum subsp. oreganum)

Cobweb House-leek (Sempervivum arachnoideum)
