Sedum is a genus of the Crassulaceae family. It contains about 400 species native to Africa, Asia, Europe, North America and South America. The mainly succulent plants grow erect or creeping.
Commonly, the Sedum species are known as Stonecrops.
The Orpines such as Sedum spectabile or Sedum telephium, both popular with gardeners, no longer belong to the genus Sedum. They already have been in the genus Hylotelephium for several years. However, they are still often found in the shops under their old botanical names.
