Calamagrostis x acutiflora 'Karl Foerster' (Feather Reed Grass)

Calamagrostis x acutiflora 'Karl Foerster,' commonly known as Feather Reed Grass, is an upright, clump-forming ornamental grass that is highly valued for its elegant, vertical growth habit. It features narrow, arching green leaves and tall, feathery flower plumes that emerge reddish-bronze and mature to golden tan, remaining attractive throughout the fall and winter. Its year-round structure and low-maintenance nature make it a favorite in modern landscapes, borders, and naturalistic gardens.

Calamagrostis x acutiflora 'Karl Foerster' thrives in well-drained soils and is adaptable to a range of conditions, including clay and sandy soils. It tolerates both moist and dry conditions, making it versatile for various garden settings. This grass requires minimal maintenance—cut it back to the ground in late winter or early spring before new growth emerges. It pairs well with flowering perennials such as echinacea, rudbeckia, and salvia, creating dynamic contrasts in color and texture. Deer- and rabbit-resistant, this grass is also attractive to birds, which may use its plumes for nesting material.
