Houseleeks or Liveforever (Sempervivum) are a genus of about 40 species of succulent plants of the Crassulaceae family which grow in rosettes. Another name used for some species (and also for some plants in other related genera) is Hen and Chicks. They occur from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, and the Caucasus. Their ability to store water in their thick leaves allows them to live on sunny rocks and stony places in the montane, subalpine and alpine belts. Although their subtropical cousins are very frost-sensitive, Sempervivums are among the most frost-resistant succulents, making them popular garden plants. They require only moderate water and some protection from extreme exposure to the sun. Perfect for Canada!
