Calamagrostis brachytricha

Korean Reed Grass

A graceful, clump-forming ornamental grass valued for its soft texture, arching habit, and showy late-season plumes. Fine green foliage forms a fountain-like mound, topped in late summer by airy, pink-tinged flower panicles that mature to silvery beige and persist into fall.

Growth is well-mannered and non-invasive, adding movement and a naturalistic feel to mixed borders and woodland edges.
