Grass Cal. Overdam Var. Feather Reed

Overdam Var. Feather Reed Grass

Calamagrostis × acutiflora ‘Overdam’ is a cool-season ornamental grass valued for its upright, vertical habit and striking variegated foliage. Narrow green leaves edged with creamy-white emerge in spring, forming a tidy clump, followed by airy, upright flower plumes in early summer that emerge with a soft pink tint and mature to tan, persisting into winter for added interest. Its strong vertical lines make it ideal for structure in borders and modern plantings.
