Plant in a sunny or lightly shaded spot with soil that drains well, adding grit and compost if your ground is heavy. In pots, use a sturdy container with drainage holes and a free-draining mix such as loam-based compost with added grit, and water regularly through summer.

Protect plants in winter with a thick mulch of well-rotted organic matter and cover the crown with horticultural fleece during hard frosts. As growth picks up in late spring, remove any dead or damaged leaves to keep the plant tidy and encourage fresh new foliage.
