Crocus speciosus, with common name Bieberstein's crocus, is a species of flowering plant in the genus Crocus of the family Iridaceae.


The plant is native to north and central Turkey, Armenia, Georgia and the Caucasus, Azerbaijan and northern Iran, and areas of Central Asia, and southern Ukraine and the Crimea.


Crocus speciosus is a cormous perennial growing to 10–15 cm (3.9–5.9 in) tall.

The lilac flowers with paler coloured throats and dark veins appear in autumn (fall). The orange styles are much-divided. As it increases rapidly, this species is suitable for naturalisation in grass.[1]

The specific epithet speciosus means "showy".[2]


Crocus speciosus is cultivated as an ornamental plant.

The plant species, [3] and the white cultivar 'Albus', [4] have gained the Royal Horticultural Society's Award of Garden Merit.
