Planting & care

Help it thrive

Planting guide

Plant in spring or autumn in a sunny, well-drained position. Improve heavy soils with grit or horticultural sand before planting. Water regularly during establishment, then only occasionally once settled.

Care tips

Avoid rich or heavily fertilised soil, as this can lead to weaker growth. Deadhead if preferred, though spent blooms provide attractive winter structure. Divide clumps only when necessary, as plants prefer to remain undisturbed.

Winter care

Leave faded flower heads in place through winter for structure and wildlife interest, then cut back old growth in late winter or early spring. Avoid overly wet soil during colder months.
