It can grow to be 2 to 5 feet tall, so placement must be made accordingly. Butterflies and other wildlife are attracted to the habitat this plant provides.12

Siting: Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best in full sun. An adaptable plant that is tolerant of drought, heat, humidity and poor soil. Plants usually re-bloom without deadheading, however prompt removal of spent flowers improves general appearance. Freely self-seeds if at least some of the seed heads are left in place.12

Care: Plant in suitable site with adequate soil organic matter so that the crown of the plant is at the soil surface18. Ensure the soil is adequately moist immediately after planting. Keep soil moist but not soggy until plant is established. Once plant is established water deeply but infrequently whenever the soil surface is dry or almost dry 2” below the soil surface.18

Pests: Plants are relatively pest resistant if preferences are met, but Japanese beetle and leaf spot are occasional problems.
