Pruning: Cut back the spent flower heads to encourage a second bloom. Remove dead or damaged leaves to keep the plant looking its best.

Propagation: Can be propagated by seed in the fall or by division in the spring. Root cuttings can also be taken in late fall or early spring.

Pests and Diseases: Generally pest-resistant, but watch for signs of aphids or whiteflies. powdery mildew and root rot can occur in overly wet conditions.
