Planting & care

Help it thrive

Planting guide

Plant in spring or autumn in fertile, well-drained soil. Position in full sun for the best flowering performance. Space plants well to encourage airflow and water regularly while establishing.

Care tips

Deadhead spent blooms to prolong flowering and divide congested clumps every few years in spring. Water during prolonged dry periods, especially in lighter soils.

Winter care

Leave seed heads standing through winter for wildlife interest and protection, then cut stems back in late winter or early spring before new growth emerges. Mulch lightly in colder areas.
