Karl Foerster Feather Reed Grass

Karl Foerster Feather Reed Grass (Calamagrostis × acutiflora ‘Karl Foerster’) is a clump-forming ornamental grass prized for its upright, architectural form and feathery flower plumes. Thriving in full sun to part shade and adaptable to most soils, it brings vertical interest from early summer through winter. Hardy in Canadian zones 3–9, it’s low-maintenance and deer-resistant—perfect for borders, mass plantings, or as a striking specimen.
