Colchicums are commonly known as autumn crocuses, although there are also real Crocus species that flower in autumn - and there are a few Colchicum that flower in spring! Most of them have bright pink flowers, some of them with tessellated patterns of darker pink or purple, and there are varieties with pale pink or white flowers. In most cases the foliage appears in the spring, dying back in summer. See also varieties of Colchicum alpinum, and Merendera.

Colchicum corsicum is a neat, compact variety having delicate lilac-pink flowers, with rich yellow stamens, in autumn. The narrow foliage, which follows the flowers, forms tidy clumps.
