Colchicum is a genus of flowering plants containing around sixty species of perennials which grow from corms. It is a member of family Colchicaceae, and is native to West Asia and part of the Mediterranean coast.

Colchicum autumnale, commonly called Autumn Crocus or Naked Ladies, is the best known species. It produces purple, pink or white flowers resembling those of the crocus which appear from September to October in its native latitudes. It forms a rosette of dark green leaves, but only after flowering.

Several other species such as C. speciosum, C. album, C. corsicum and C. agrippinum are grown for their flowers.

Its leaves, corm and seeds are poisonous, containing the alkaloid colchicine. Its roots and seeds have long been considered to have valuable medicinal properties deriving from the use of small doses of this drug, such as to treat gout.
