Slender lavender-purple crocus that naturalises into great sheets under deciduous trees. Among the earliest crocuses and notable for being largely ignored by squirrels.

| RHS hardiness rating | H7 | down to −20 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 3–8 | −34 °C to −1 °C | Plant tolerates down to this zone |

Growing notes
- Flowers in late winter to very early spring — among the earliest crocus species in the garden
- Naturalises by seed and corm offsets, often forming carpets in lawns and woodland
- Far more resistant to squirrel and mouse predation than other crocus species — useful where other crocuses are eaten
- Needs winter chilling to flower reliably
