In containers: It grows well in containers, provided the pot is at least 15 cm deep and has excellent drainage.

Division

1. Dig up the clump after flowering.
2. Gently pull the root mass apart into smaller sections.
3. Replant immediately in moist soil.

Seed

1. Collect seeds when pods turn brown.
2. Sow fresh seeds in trays.
3. Keep in a cool, bright spot until germination.

Plant these near deciduous shrubs that provide light shade during the heat of the summer.
