About

Colchicum ( KOL-chik-əm or KOL-kik-əm) 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). All species in the genus are toxic.

How to grow it

Temperate colchicums are commonly grown in gardens as ornamental flowers. Species found in cultivation include:

There are also cultivars and hybrids such as:-

Uses

Plants in this genus contain toxic amounts of the alkaloid colchicine which is used pharmaceutically to treat gout and familial Mediterranean fever. The use of the roots and seeds in traditional medicine is thought to have arisen due to the presence of this drug.
