It is grown for its tall stature (up to 6 feet) and showy, cream-colored plumes of flowers in summer. The effect is that of a giant astilbe.

Grow in a woodland garden or moist border, or at waterside. Noteworthy Characteristics: Tall, native perennial with showy plumes of creamy-white or greenish-white flowers in summer. Care: Grow in moist, fertile soil in full or partial shade. This species can also tolerate drier conditions in full sun. Deadhead to control unwanted seedlings. Propagation: Divide in early spring or fall. Sow seed in a cold frame in autumn or spring. Self-sows freely. Problems: Generally easy to grow, but fly larvae and tarnished plant bugs may be problems.
