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 18 cm (7 in) tall by 10 cm (4 in) wide, it is an herbaceous perennial growing from corms. C. speciosum blooms in the fall, producing reddish/violet flowers on stems up to 30 centimetres (12 in) 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.
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' which, together with its parent, has gained the Royal Horticultural Society's Award of Garden Merit.
Colchicum speciosum var. bornmuelleri (syn. Colchicum bornmuelleri Freyn) has bowl-shaped, white-throated flowers with emerald-green tube and brownish anthers.
