Grown in gardens for thousands of years. Sempervivum means “live forever.” Romans planted Hens and chicks on their roofs to ward off lightning. As a succulent it holds water and is probably more difficult to catch fire. “This practice was preserved for historians when Charlemagne (720-814), first Holy Roman Emperor and unifier of a large part of northern Europe, ordered that all villagers within his crown lands plant houseleeks on their roofs, presumably as a safety measure. He decreed: Et ille hortulanus habeat super domum suam Iovis barbam. (And the gardener shall have house-leeks growing on his house. Capitulare de villis, about 795, LXX.)”
