I lost a large amount of rosettes of Silberkarneol and Turmalin this winter, though. Fortunately, the surviving ones produced many new plants. I'll be more vigilant next winter for both of them. The other varieties didn't suffer at all from the cold (-20°C) and wet winter we had.
My avatar is Sempervivum calcareum Limelight, one of my favorites.
I'd like to create a new entry for it (and a couple of others too), would you please correct it? (guess you check suggestions anyway, but being a novice I would appreciate you bringing any error to my attention)
