|Madagascar rosy periwinkle|
Catharanthus roseus, commonly known as the Madagascar periwinkle, rose periwinkle, or rosy periwinkle, is a species of flowering plant in the dogbane family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant, a source of the drugs vincristine and vinblastine, used to treat cancer. Other English names include '“Cape periwinkle” and "old-maid". It was formerly included in the genus Vinca as Vinca rosea.
