Growing it

Propagation: division, seed
When to plant: spring, autumn
Overwintering: The rhizomes are hardy and do not require special protection in winter. Simply leave the area undisturbed as the plant emerges naturally in spring.
In containers: It is not well suited for containers due to its specific woodland soil and dormancy requirements.

Division

1. Wait until the plant goes dormant in summer.
2. Carefully dig up the rhizome mass.
3. Cut the rhizomes into sections with at least one bud.
4. Replant immediately in moist, organic soil.

Plant in groups with other spring ephemerals to create a lush woodland floor that transitions gracefully into summer dormancy.
