I have a colony of S. dolomiticum x montanum in bloom. This is one of my favorites and a hybrid between two semp species. It stays about 1-1.5" and always a nice fuzzy green. I like the soft fuzzy ones for some reason. You don't mind touching them while working with them. I will remove the flower heads before seeds mature so that the colony will stay pure. Next spring, this container will be a mess with so many rosettes dying until the offsets fill in again.
