Growing in one of my troughs, and not looking like any of the draba species I've grown from seed in recent years. I can't find a match for the shape of the basal foliage combined with the leafyness of the flower stem. Any ideas?
It looks like all the flowers each have five petals. I don't think it could be a Draba then...
Maybe some kind of Myosotis?
I believe it's Erinus alpinus. (Draba spp. have 4 petals.)
Ahem, yes, not a draba of course. There was supposed to be an Erinus in that trough, but I thought it had perished (along with all the other ones I've ever tried to grow. It was supposed to be 'Dr Hahnle', which like most erinuses blooms in the pink range, so I never even considered that this might be it. I'll look into it more closely - thanks for setting me straight.
Here is a photo of Erinus alpinus 'Alba' for comparison. The vertical axis of symmetry of the flower is distinctive.
Yeah, looks about right - thanks!
