Easily grown in average, dry to medium moisture, well-drained soils in full sun to part shade. Best in full sun. This is an adaptable plant that is tolerant of drought, heat, humidity and poor soil. Divide clumps when they become overcrowded (about every 4 years). Plants re-bloom well without deadheading, however prompt removal of spent flowers encourages continued bloom and improves general appearance. Leave some seedheads if you want the plants to reseed, and to feed the birds.
