Planting guide

Plant in spring or early autumn in well-drained soil in a sunny position. Improve drainage with grit or compost if needed. Space plants generously to allow air circulation and avoid waterlogging around the crown.

Care tips

Remove spent flower spikes to prolong the display. Divide congested clumps in spring to maintain vigour. Avoid overly wet winter conditions to protect the crown.

Winter care

In autumn, tie foliage loosely to protect the crown from excess moisture. Apply a dry mulch around the base in colder regions. Avoid cutting back foliage until spring, when new growth appears.
