Colchicum speciosum is a species of flowering plant in the family Colchicaceae, native to mountainous areas of northern Turkey, the Caucasus and northern Iran. Growing to Шаблон:Convert tall by Шаблон:Convert wide, it is an herbaceous perennial growing from corms. C. speciosum blooms in the fall, producing reddish/violet flowers on stems up to Шаблон:Convert tall without any leaves present. The strap-like leaves grow in the spring, then yellow, wither and die back as summer progresses. The flowers strongly resemble those of the crocus, the familiar spring-flowering bulb; hence the common name autumn crocus which is applied to this and other colchicum species. However the two genera belong to different families; and there is in fact an autumn-flowering crocus species, Crocus sativus, the source of the spice saffron. By contrast, all parts of Colchicum speciosum are toxic if ingested.

Cultivation

Colchicum speciosum is a vigorous grower and does well in full sun to partial shade and well-drained soils in most climates. It is valued in gardens for its late flowering at the end of summer and into autumn.

Cultivars include the white 'Album' and the amethyst-purple ‘Atrorubens’ which have gained the Royal Horticultural Society's Award of Garden Merit (confirmed 2017).
