Planting

Choose full sun and soil that drains freely, including poor or rocky ground. Its compact growth also fits containers, with cooler summer conditions giving the best results.

Care

Remove faded flowers to reduce seeding and encourage further blooms. Cutting back to the basal leaves after flowering keeps it tidy; divide clumps when they need reducing.

Before planting: It can seed beyond its intended space if spent flowers are left in place.
