Karl Foerster's Feather Reed Grass (Calamagrostis  × acutiflora 'Karl Foerster')
kal-ah-mah-GROS-tiss ex ah-kew-tih-FLOOR-ah
Genus:  Calamagrostis

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

Noteworthy Characteristics: 

Considered drought tolerant and deer resistant once established. Attracts birds to the garden.

Care: 

Leave foliage and flowers for winter effect, cut back in early spring near ground. Does not reseed. This is an excellent choice of grass for creating a hedge, backdrop or screen effect.

Propagation: 

Divide in mid-spring.

Problems: 

Ergot, powdery mildew, tar spot, smut, and foot rot can occur.
