Easily grown in average, dry to medium moisture, well-drained soils in full sun. Drought tolerant. Tolerant of poor soils. Can spread somewhat rapidly by stolons to form colonies in optimum growing conditions, particularly in rich fertile soils which should be avoided and in cool northern climates where it is more robust. Remove spent flower stalks after bloom. Sparse rebloom in late summer-early fall may occur. Plants need to be divided every 2-3 years.
