What Are Sempervivum?
Sempervivum, known as houseleeks, are a genus of about 40 species of succulent plants of the Crassulaceae family. Another common name is hen and chicks. They grow as evergreen perennial rosettes.
Sempervivum has a wonderful ability to survive dryness. They have a remarkable progression of color changes throughout the year. They are monocarpic and thus will flower and die, but they normally produce several generations of chicks before that happens.
There are 40 species, and there are hundreds of varieties of hybrids.
