Care
Plant in full sun or partial shade in Zones 7 and warmer, in moist, well-drained soil. Good drainage is critical or these flowers may die out in winter in Zones 6 and colder. Fertilize by working in compost two or three times during the season or by applying a slow-release fertilizer, following label directions exactly. Deadhead regularly or cut back after first flush of flowering to promote reblooming. Mulch in winter in colder climates. Stake taller varieties.

Planting
Plant established plants in spring. Divide in early spring or fall every two years or as needed.

Pests and Diseases
