I've visited the plant this summer - I'd say E. x pseudovirgata, and probably the same as the 1966 plant. Also mentioned in I Lawrence's Wild Flowers of Cleveland. Same or v similar plant also found on Seal Sand roundabout, near the fire station! Yet another alien gem!

Back from the fantastic @bsbibotany.bsky.social Mentha workshop run by @ambroisebaker.bsky.social. I learnt a lot, mints can be so variable.

On the field meeting we found a number of different species. First photo is M. x gracilis, second is M. x smithiana and third is M. x verticillata.

Back at base, and we looked at the hairs in the throat of the calyx tubes. This was fascinating.
Mentha pullegium (right) compared with M. x gracilis.
Both had hairs within the calyx tube, but M. pullegium had a clear cone-shaped, ring of hairs.

Thanks Alex for coming to the workshop and for posting these pictures - There are other double and triple hybrids that have not been found in Britain and Ireland to date, so the mint quest continues....

A few hybrid Mentha from an excellent weekend in NE Yorks looking at mints with @ambroisebaker.bsky.social & @bsbibotany.bsky.social friends. Mentha x smithiana was new to me:) Names & notes on alt #wildflowerhour
Mentha x gracilis (spicata x arvensis): thinly hairy, campanulate calyx, herby-spearmint scent Mentha x piperata (spicata x aquatica): long terminal inflorescence, peppermint scent! Mentha x smithiana (aquatica x spicata x arvense): peppermint-gone-wrong scent, long petioles, long whirled inflorescence Mentha x verticillatum (arvense x aquatica): bad scent (neither parent smells great), hairy, leafy whorled inflorescence

Thank you Astrid for coming along the workshop, this was a tremendous weekend. Fair to say that we have all learnt a lot! And still so much to learn!

A wonderful Mint workshop with @ambroisebaker.bsky.social in Yorkshire. Some really interesting mint species and hybrids were seen.
M. x smithiana (aquatica x spicata x arvense).
With M. x verticillata (arvense x aquatica) nearby and long-gone M. spicata possibly from a nearby garden.

M. suaveolens as an alien can look like that!
ambroisebaker.bsky.social
Hi Benrl... where did you find this one? Alnwick again? Wow! Another v interesting specimen. It has got a lot of M. suaveolens characteristics, but does not quite fit as you spotted. I'd be very cautious about naming it straight away, before observing more into detail. Specimen and/or location?
ambroisebaker.bsky.social
One more thing - I see that there are no recent records of M. x smithiana in the Alnwick area - would you send me the location? or submit your record to the BSBI (with due reservation about the identification)? Thanks!
ambroisebaker.bsky.social
My pleasure, don't hesitate to send me pictures of mints!
The key in Stace mostly gets you to the right direction but it can be hard to use!
Good luck

Lovely specimen - yes ID looks correct from pictures
ambroisebaker.bsky.social
A good question! I suspect nice for herbal tea!
ambroisebaker.bsky.social
I guess that's a shaded shoot! Are you 100% sure it is from the same clone? The calyx looks ok for smithiana but this is very hairy for it.
Interesting site, happy to receive specimens to confirm ID... If I can! And if at all possible ;-)
ambroisebaker.bsky.social
Colour and general look points to smithiana but would need to check calyx size and shape, fertility and smell!
Nice one!
ambroisebaker.bsky.social
This should be checked for the triple hybrid M.x smithiana. Other contenders are x gracilis and x vert. There is clearly the influence of arvensis inflorescence shape (leaf like bracts) but this looks like an hybrid (there is a gradation from leaf like bracts to tiny bracts).
ambroisebaker.bsky.social
Looking correct but may require a revisit? Wow v interesting!
ambroisebaker.bsky.social
I have also found this one , i'd call rubrum
ambroisebaker.bsky.social
Here is what I believe to be hybridum, just submitted via bsbi app
Chenopodiastrum hybridum
