Pruning: Remove the foliage only after it has turned yellow and withered away naturally.
Repotting: Divide the bulbs every few years if they become too crowded in their spot.
Soil: Well draining, fertile soil
Soil pH: 6.0 to 7.5
Temperature: -34 to 30°C
Humidity: 40 to 70%

Signs it needs repotting

Corms are crowded and pushing out of the soil.

Growing it

Propagation: division, seed
When to plant: late summer
Overwintering: No special winter care is needed as the corms are hardy, but ensure the soil is well drained to prevent rot.
In containers: It is best grown in the ground, but can be kept in pots if the soil is allowed to dry out during the summer dormancy.

Division

1. Wait until the foliage has completely died back in summer.
2. Carefully lift the corms from the soil.
3. Separate the offsets from the main corm.
4. Replant the corms immediately at the same depth.

Pair with low growing perennials that do not mind the dormant summer period when the bulb needs dry soil.

Grows well with

Hosta · Their large leaves help hide the dying foliage of the colchicum in late spring.
Creeping Phlox · It provides a low growing carpet that complements the autumn blooms.

Similar species

Crocus · They look similar but are unrelated and bloom at different times.
