Easily grown in average, medium to wet soils in full sun to part shade. Tolerates a wide range of soils, including dry ones, but prefers moist, sandy or clay soils. May flop in overly rich soils. Generally performs best in full sun. Will grow in part shade, but begins to lose its form in too much shade, growing more openly and possibly falling over. Grows primarily in clumps, but may slowly spread by creeping rhizomes. Cut back clumps to the ground in late winter to early spring.
