Calamagrostis x acutiflora 'Karl Foerster' (Feather Reed Grass) - An evergreen grass in mild climates, this grass is distinguished by its feathery loose purple-tinged flowers on stalks to 6 feet tall in summer that age to a buff color by late summer. Flowers move gracefully in the wind. Foliage mounds are usually around 3 feet tall and 3 feet wide. Plant in full sun to light shade and give regular irrigation. Cut back in late winter to maintain clean fresh foliage. It can be used as a specimen plant or in borders. Calamagrostis x acutiflora cultivars are the result of crossing Calamagrostis epigejos with Calamagrostis arundinacea. Flowers are good for fresh or dry arrangements. Perennial Plant of the Year 2001.
