Easily grown in average, medium to wet, well-drained soil in full sun to part shade. Prefers constantly moist, alkaline soils. Intolerant of drought. Appreciates part shade in hot climates. Propagate by seed or by dividing clumps in early spring. Freely self-seeds. With sufficient moisture, foliage may remain attractive throughout the growing season. If foliage depreciates in summer, cut back hard to promote new growth.
Although this plant freely self-seeds, foliage variegation of the new plants may not come true, so prompt deadheading of spent flower plumes is generally advisable.
