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).
