Calamagrostis brachytricha, commonly known as Reed Grass or Korean Feather Reed Grass, is an ornamental perennial grass valued for its graceful habit and showy, late-season flower plumes. This clump-forming grass typically grows 3 to 4 feet tall in bloom and forms an attractive mound of arching green foliage. In late summer to early fall, it produces soft, feathery flower heads that emerge pinkish-tan and mature to silvery tones, creating a striking contrast against the foliage. Calamagrostis brachytricha thrives in full sun to part shade and prefers moist, well-drained soils, making it a versatile choice for mixed borders and naturalistic plantings.
