Colchicum autumnale resembles an oversized crocus and blooms in autumn—without any foliage. Its leaves appear in spring but wither away before flowering begins. For best results, plant Colchicum bulbs in August in moist, nutrient-rich soil. A sunny location is ideal. Plant the bulbs 10–20 cm deep, in small groups of five to ten, spaced 15–20 cm apart. Once established, they bloom more abundantly each year. They are fully hardy and require little maintenance.

Autumn-flowering crocuses, such as Crocus sativus (saffron crocus), are smaller than Colchicum but just as striking. They are well-suited to naturalising in warm, sunny locations. Crocus sativus thrives in well-drained, clay-limestone soil that’s rich in organic matter.
