Growing it

Propagation: seed, division
When to plant: spring, autumn
Overwintering: In cold climates, apply a light layer of mulch to protect the crown from freezing and thawing cycles. They generally remain semi-evergreen in mild winters.
In containers: They are excellent for pots and window boxes, provided the container has good drainage.

Division

1. Carefully lift the clump from the soil in early spring.
2. Gently pull the root ball apart into smaller sections.
3. Replant the divisions immediately at the same depth.
4. Water thoroughly to settle the soil.

Plant these at the base of taller perennials to act as a living mulch that keeps roots cool.
