Hairy crocus: complete guide

Overview

Hairy crocus (Crocus pulchellus) is an autumn-flowering species native to the Balkans and northwestern Turkey. This member of the Iridaceae family brings welcome color to the garden when many other flowers are fading. Named for the distinctive hairy stigmas visible inside each bloom.

Appearance and bloom

This compact crocus reaches approximately 10-15 centimeters in height with narrow, grass-like foliage. The flowers are bright purple to violet with distinctive hairy orange stigmas that add unique interest. Blooming from September through October, these flowers provide a welcome color injection when autumn fades.
