Calamagrostis × acutiflora ‘Karl Foerster’ (Feather Reed Grass) #3

Description Calamagrostis × acutiflora ‘Karl Foerster’ is a strongly upright deciduous ornamental grass valued for its narrow vertical form and early-season flowering. Mature plants typically grow 4–5 feet tall and 2–3 feet wide, forming tight clumps with a distinctly vertical habit. The foliage consists of narrow medium green blades that grow in dense upright clumps, maintaining a neat appearance throughout the growing season. In late spring to early summer, slender stems rise above the foliage bearing feathery pinkish-bronze flower plumes that gradually mature to wheat-colored seed heads, persisting well into fall and winter for added structure. Calamagrostis × acutiflora ‘Karl Foerster’ is commonly used as a vertical accent, screening plant, border planting, or mass planting. Its rigid upright growth and uniform habit make it especially suitable for formal landscapes and modern designs.
