Sedum is the large stonecrop genus of the Crassulaceae, representing about 400 species of leaf succulents, found throughout the northern hemisphere, varying from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have 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 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.
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 "prickmadam," "stone orpine," or "crooked yellow stonecrop," is occasionally used as a salad leaf or herb in Europe (incl. 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 and isopelletierine) which give it a sharp, peppery and acrid taste and make it somewhat toxic. Depending on the amount consumed, it may cause irritations of the mucous membranes, cramps, paralysis, and respiratory paralysis. In ancient Greece, Sedum acre was used to treat epilepsy and skin disease, as well as inducing miscarriage.
[edit] Sedum roofing
Sedum can be used to provide a roof covering in green roofs.[1] They are preferred to grass for green roofs.[2]
