Large deep blue flowers 12mm
Hairs all around stems
No interactions present.
Steve, did you key this right out? Are you certain? It is difficult to tell from a photo, which is why, probably, there are no agreements (rare that)
[moremoth did as I wrote this].
I'd be interested to know what to look for as it is recorded here (but seems to be absent).
I didn't key it out. I don't have experience of using keys so my ID is based primarily on flower size and colour and leaf shape. Then much staring at images of the most likely possibilities.
Unfortunately there is variation in the flower size stated in the books I have.
I checked the speedwells out in Rose. This looks like a V. persica except that the flowers are all blue, no white lower lip, and I can see the oval pointed sepals Rose gives as a distinguishing feature. I agreed to V. polita on that basis.
But Germander Speedwell has long spikes of multiple flowers, and the lower petal is smaller than the other three. This doesn't fit the description.
I have now measured the flowers which are 12mm and over. Stems are hairy but hairs not in rows.
Extra image added of sepals.
The flowers are far too large for Grey Field Speedwell so I have to concur with the ID of V. persica! Despite the flowers not having a white lower petal.
...an excellent process to get this far and proves the value of the Comment section.
AND having the right Filter ticked in My Spot
My handy flower book "Collins complete guide to British wild flowers" put the flowers of polita as larger than that of persica. That, combined with petal colouring led me to think this must be polita. However, further research indicates that the flowers would be smaller and I've now seen many examples of images of persica flowers which are all blue. Thanks all for working through this with me.
