Desertkoigal, here is some info, the first link gives some history of sempervivum cultivation, which explains why its important not to "guess" at a cultivar. There are many of us on here who have what we call 'NOID's meaning No identification. If someone has many cultivars that look alike and have lost their label it may be better to call them NOIDs
Toby from Young's garden center video taped and posted these. They are from a workshop which happened in April.
Also, for those who did not receive a copy of the handout and want it, Toby has scanned it and converted it to a pdf file.
