Planting & care

Help it thrive

Planting guide

Plant in spring or autumn in well-drained soil. Choose a sunny or partially shaded position with space to spread. Avoid disturbing once established, as it resents root disturbance.

Care tips

Water well during dry spells in the first season. Remove spent flower spikes to tidy the plant. Divide clumps only if necessary, as plants prefer to remain undisturbed.

Winter care

Cut back faded flower spikes and damaged foliage in autumn or early spring. Apply a mulch in colder areas to protect the crown during severe frosts.
