description Colchicum autumnale Overview
Colchicum autumnale, commonly known as autumn crocus or meadow saffron, is a toxic autumn-blooming perennial native to Europe. The plant grows from underground corms and produces purple, crocus-like flowers in the fall, while its broad leaves emerge separately in the spring before dying back. It contains the potent alkaloid colchicine, which has been used medicinally for centuries and remains a standard clinical treatment for acute gout flares. Due to the high toxicity of all its parts, it is generally cultivated only as an ornamental bulb plant in specialized gardens.
help Colchicum autumnale FAQ
Why is Colchicum autumnale called autumn crocus?
It produces crocus-like lavender or purple flowers in autumn, even though it is not a true crocus. True crocuses belong to the iris family, while Colchicum belongs to the family Colchicaceae.
When do the leaves of Colchicum autumnale appear?
The broad, strap-shaped leaves appear in spring, separately from the autumn flowers. The RHS describes the plant as producing up to six autumn flowers and leaves that can reach about 30 centimetres.
Is Colchicum autumnale poisonous?
Yes. The whole plant contains colchicine and is toxic if eaten. It can also be confused with edible wild garlic when the leaves appear, so it should not be collected for food.
Does Colchicum autumnale grow from a bulb?
It grows from an underground corm, not a true bulb. The corm stores energy for the separate flowering and leaf-growing phases of the plant’s yearly cycle.
