By the way, I did send Edelweiss (the source of your mislabelled "Draba androsacea") a note to say that what they are selling is definitely not Draba androsacea/D. fladnizensis, and that it appears to be Arabis androsacea. I don't order from Edelweiss so don't tend to look at their site, but it's up to them whether they correct their plant list or not. It seems fairly common to get a mislabelled plant where someone has just mixed up tags between otherwise correctly-ID'd species, a little less common at a specialist nursery that a plant is totally misidentified like this case, but it happens, needless to say.
