Care Guide

Cultivation

Best grown in a sandy soil that has been enriched with humus but any deep, moist but well-drained soil will do. Full sun is best; can tolerate partial shade but flowering is reduced. The smaller stature of this cultivar makes it well-suited to smaller gardens

Pruning

Old flower stems can be cut down after flowering

Propagation

Propagate by division of established clumps in late spring. Propagate by taking offshoots from the crown

Diseases
