Easily grown in average, dry to medium, well-drained soil in full sun. Tolerates very light shade. Tolerates drought. Prefers moist soils with good drainage. Plants may repeat bloom throughout the summer, but need regular moisture to encourage this. Remove spent flower spikes to help extend the bloom period. Cutting back flowers stimulates repeat bloom. Cut plants back after flowering has concluded.
