Growing it

Propagation: seed, cuttings
When to plant: spring, autumn
Overwintering: No special winter care is needed as it is fully hardy. Simply leave the dried flower heads for winter interest and wildlife food.
In containers: It is not well suited for long term container growth due to its large size and extensive root system.

Seed

1. Collect seeds in late autumn when pods are dry.
2. Sow seeds in a cold frame or unheated greenhouse during winter.
3. Transplant seedlings into individual pots once they have two sets of true leaves.

Softwood Cuttings

1. Take cuttings in late spring from new growth.
2. Dip the base in rooting hormone.
3. Place in a well draining medium and keep humid until rooted.

Plant in groups of three or five to mimic natural thickets and provide the best habitat for local birds.
