Calamagrostis x acutiflora 'Karl Foerster' Feather Reed Grass

Calamagrostis x acutiflora ‘Karl Foerster’ is the first ornamental grass to receive the Perennial Plant of the Year Award™ (2001), earned for good looks, long-lasting plumes and undemanding growing requirements. Green foliage grows in a neat, 2-foot clump. In early spring, stalks rise up to 6 feet, capped with elongated, wheat-colored seed heads. In addition to intrinsic beauty, Feather Reed Grass exhibits tolerance for heavy clay and compacted soil and will not reseed (seeds are believed to be sterile). Plant Feather Reed Grass in sunny, dry locations and use as a backdrop for flowering perennials. Calamagrostis x acutiflora ‘Karl Foerster’ was named in honor of the late great nurseryman, Karl Foerster (1874-1970). Mr. Foerster was responsible for introducing this grass, as well as many other acclaimed plants during his distinguished career in horticulture.
