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.[2]

The specific epithet speciosus means "showy".[3]


Crocus speciosus is cultivated as an ornamental plant.

The plant species,[4] and the white cultivar 'Albus',[5] have gained the Royal Horticultural Society's Award of Garden Merit.
