Growing it

Propagation: division, seed
When to plant: spring, autumn
Overwintering: Leave the foliage intact through winter to protect the crown from frost and moisture. Trim back dead material only when new growth begins in spring.
In containers: It can grow in large containers, but ensure the pot is at least 50 centimeters wide to accommodate the root system.

Division

1. Dig up the clump in early spring.
2. Use two garden forks to pry the root ball apart.
3. Replant the divisions immediately in well-drained soil.

Seed

1. Sow seeds in pots during spring.
2. Keep the soil lightly moist until germination.
3. Transplant seedlings once they are large enough to handle.
