  Rosettes of succulent leaves

  Size: 4” x 4”
  Care: sun in well-drained to moist well-drained soil
  Native: Alps & Pyrenees Mountains

  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.)”
