Care guide

Plant in full sun in well-drained soil. Tolerates drought, wind and salt air superbly. Protect in winter with mulch around the base, or keep as a container plant in cold areas. Water sparingly — wet feet lead to root rot. No special feeding needed.

Pruning tips

Remove dead and damaged leaves by cutting them at the base. Cut away the spent flower stalk. Divide overcrowded clumps in spring. Wear gloves — the leaf edges can cut.
