description Colchicum Overview
Colchicum is a genus of corm-forming flowering plants native mainly to Europe, North Africa, and parts of western and central Asia. Many species produce crocus-like flowers in autumn, often before their leaves emerge, which explains the common name autumn crocus even though Colchicum is not a true crocus. The plants contain colchicine, a toxic alkaloid used in medicine for gout and other conditions, so the corms, seeds, and foliage must not be eaten.
help Colchicum FAQ
What is Colchicum?
Colchicum is a genus of corm-forming flowering plants native mainly to Europe, North Africa, and western and central Asia. Many species produce crocus-like flowers in autumn.
Why is Colchicum called autumn crocus?
Many Colchicum species bloom in autumn, often before their leaves appear, and their flowers resemble crocuses. They are not true crocuses, which belong to the genus Crocus in the iris family.
When do Colchicum leaves appear?
In many species, the flowers appear first and the broad leaves emerge later. This unusual seasonal sequence is one of the easiest ways to distinguish Colchicum from a spring crocus.
Is Colchicum safe to eat?
No. Colchicum plants contain colchicine and are poisonous if eaten. They should not be confused with edible saffron crocus, whose stigmas come from Crocus sativus.
