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