C coum being smothered by corydalis

What Corydalis is this, it is exuberant.

I'd have to check as I have several named blue ones. it is equally likely that it was just a 'blue' un-named one from the HPS table at our local group. It takes splitting well. would you like a little bit?

Oh I am tempted, but in the past I have not done well with blue Corydalis flexuosa Pere David. Does this one need acidic soil? I am surprised it is evergreen.

well mine is growing on soil over chalk but I mulch with beech leaf mould which is acidic. it isn't a fully evergreen one though. my pere david didn't stay around for long either. so if you want a bit to give it ago I wont mind if it curls up and dies :o)
