"Colchicum is a genus of perennial flowering plants containing around 160 species which grow from bulb-like corms. It is a member of the botanical family Colchicaceae, and is native to West Asia, Europe, parts of the Mediterranean coast, down the East African coast to South Africa and the Western Cape. In this genus the ovary of the flower is underground. As a consequence, the styles are extremely long in proportion, often more than 10 cm (4 in).

The common names "autumn crocus", "meadow saffron" and "naked lady" may be applied to the whole genus or to many of its species; they refer to the "naked" crocus-like flowers which appear in late summer or autumn, long before the strap-like foliage which appears in spring.

Colchicum autumnale and its cultivars are widely grown in temperate regions. Several other species, such as C. speciosum, C. album, C. corsicum and C. agrippinum, are also grown for their flowers.

Colchicum melanthioides is probably the best known species from the tropical regions. In contrast to most temperate colchicums the flower and leaves are produced at the same time, the white flowers are usually a small corymb which is enclosed by white bracts. Close relatives (such as Colchicum scabromarginatum and Colchicum coloratum) have flowers with very short stalks and might be pollinated by rodents."
