Crassulaceae (Stonecrop Family)

Members of Crassulaceae usually have fleshy leaves, are perennial, have 5 separate sepals, 5 petals, 5 or 10 stamens, and a pistil with 5 divisions. The annuals in the genera Crassula and Parvisedum, however, have all this in groups of four.

 

Stonecrops (Sedum) and houseleeks (Sempervivum) have long been cultivated in dish gradens and rockeries. Sempervivum tectorum, better known as "Hens and Chicks", was once planted on tile roofs to provide protection from lightning. While this may not have been effective, its juice is believed to be useful in the treatment of ringworm and warts.
