''Colchicum speciosum''〔(World checklist of selected families )〕 is a species of flowering plant in the family Colchicaceae, native to mountainous areas of northern Turkey, the Caucasus and northern Iran. Growing to tall by wide, it is an herbaceous perennial growing from corms. ''C. speciosum'' blooms in the fall, producing reddish/violet flowers on stems up to 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.〔Steven, Christian von. 1829. Nouveau Mémoires de la Société Impériale des Naturalistes de Moscou 7: 265, t. 15. 〕 == 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'〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=518 )〕 which, together with its parent,〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=2510 )〕 has gained the Royal Horticultural Society's Award of Garden Merit.
