Sedum is the large stonecrop genus of the Crassulaceae, representing about 400 species of leaf succulents, found throughout the northern hemisphere, varying from annual groundcovers to shrubs. The plants have water-storing leaves and a typical form of blossom with five petals, seldom four or six. There are typically twice as many stamens as petals.

Well known European Sedums are Sedum acre, Sedum album, Sedum dasyphyllum, Sedum reflexum (also known as Sedum rupestre) and Sedum hispanicum.

Many sedums are extensively cultivated as garden plants, due to their interesting and attractive appearance and hardiness. The various species differ in their requirements; some are cold-hardy but do not tolerate heat, some require heat but do not tolerate cold. They are preferred to grass for green roofs, popular in Germany and some other countries.

Sedum species are used as food plants by the larvae of some Lepidoptera species including Grey Chi. In particular, Sedum spathifolium is the host plant of the endangered San Bruno elfin butterfly of San Mateo County, California.

[edit] Edibility and toxicity

Sedum reflexum, known as "stone orpine" or "crooked yellow stonecrop", is occasionally used as a salad leaf or herb in Europe (and the United Kingdom) [1]. It has a slightly astringent sour taste

Sedum acre ("biting stonecrop") on the other hand contains high quantities of piperidine alkaloids (namely (+)-sedridine, (-)-sedamine, sedinone und isopelletierine) which give it a shap, peppery and acrid taste and make it somewhat toxic. Depending on the amount consumed, irritations of the mucous membranes, cramps and paralysis, including respiratory paralysis may ensue. In ancient Greece, biting stonecrop was used to treat epilepsy and skin diseases, as well as to cause abortions.
