Culture
Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Tolerates some drought, but prefers humusy, moderately fertile soils with regular and consistent moisture plus good soil drainage. Full sun is best in cool northern summer climates, but some part afternoon shade is appreciated in hot summer climates such as the St. Louis area. Deadheading is tedious for larger plantings and probably unnecessary. Foliage may decline after flowering in hot summer climates, at which point it should be cut back and shaped to revitalize, with additional sporadic rebloom sometimes occurring later in summer. Propagate by division.
