Although often called autumn crocus, colchicums are not related to true crocuses. There are winter- and spring-flowering species, but the most common ones bloom in September and October. They flower when least expected, the large blooms suddenly appearing from the bare earth without any leaves – hence the common name naked ladies.

Colchicum speciosum bears dramatic pink-purple flowers. The flowers appear alone, with the leaves following in spring. It's ideal for naturalising in grass or at the front of a sunny border. Learn more in our grow guide for Autumn Crocus.

Grow Colchicum speciosum in well-drained soil in full sun. All parts of the plant are poisonous, so wear gloves when handling the bulbs.
