Calamagrostis  × acutiflora 'Karl Foerster'

kal-ah-mah-GROS-tiss ex ah-kew-tih-FLOOR-ah

Versatile, attractive and care-free ornamental grass with wheat-like appearance. Slender, upright, deep-green, lustrous foliage becomes effective by early spring and lasts all the way until winter. A cool season grass, 'Karl Foester' is upright and clump forming, with purplish-green, feathery plumes to 6'. It distinctively blooms in early summer rather than fall and must have winter chill to bloom. Long lived — 25 years or more. -Santa Rosa Gardens
