Crocus speciosus

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.

The specific epithet speciosus means "showy".[4]

It is cultivated as an ornamental plant. As it increases rapidly, it is suitable for naturalisation in grass.[5] The species,[6] and the white-flowered cultivar 'Albus',[7] have gained the Royal Horticultural Society's Award of Garden Merit.
