From Tenerife in the Canary Islands, Aeonium tabuliforme is a solitary low growing species. It grows to be as much as 12 inches across and only 2 inches high. It prefers light shade to full sun. After about three years it produces it's yellow flowers and dies. It can only be grown from seed.
     This one has done OK for me, the problem with brown spots isn't as severe as with some of the others. I just hope it doesn't grow too fast, there isn't room in that pot for a plant a foot across.
