Hi there, maybe there was a mix up on upload? This is a saxafrage, possibly x jenkinsae. The draba is a yellow crucifer..anyway nice plant! mark

Aha! Thank you for the ID! Not an upload problem but a mixup, apparently, on the maps for my troughs - I did acquire Saxifraga x irvingii 'Jenkinsiae' at one time, but must have mixed it up with something else on planting perhaps (according to my trough maps, anyway). I'll have to study the rest to see if I really have the Draba at all, or if perhaps, I bought something else that was mislabelled.
Thanks!
