Great pictures! I have to admit, I don't know much about sempervivum, but will pay more attention at the garden centers this spring.
I've only known sempervivum as hen and chicks, and only have one that is probably the garden variety type. It was added to my garden in 2012 after my dad passed away and I put it in his old work boots. They have grown a lot (as have the weeds and creeping phlox around them!)
