Foerster’s Feather Reed Grass (Calamagrostis x acutiflora ‘Karl Foerster’) forms narrow, upright clumps of foliage topped with tall, feathery plumes from early summer through winter. Its strong vertical lines add instant structure to borders, modern landscapes, and mixed plantings, while the seed heads provide soft movement and four-season interest. Low-maintenance, cold hardy, and tolerant of a range of soils, it is one of the most reliable ornamental grasses for full sun.
