Thanks Lynn and Spring.
Lynn, I only have 1 sempervivum, an arachnoidium I believe. I'm unsure really, they were part of my great grandmother's garden that I recently rescued. There are a ton of them though I'v broken into clumps and replanted in rock gardens. I have some pictures I took, but for some reason I cannot put them up via my playstation (my normal internet access). I'll go boot up the computer and try.
