A tidy, clump-forming perennial, feather reed grass provides a strong vertical accent with its narrow, linear leaves that arch away from stiff, upright stems. In late spring to early summer, tightly held plumes of shiny copper to pale purple?brown flowers emerge in narrow clusters along the stem tip, fade to tawny brown, and persist through winter. Notable varieties include 'Karl Foerster,' with pink to bronze flowers that fade to buff-brown, and the dramatically vertical x var.

did you know?

Feather reed grass is an interspecific hybrid (a cross between two species). It is the result breeding and species which occur naturally in Europe and Asia.

general maintenance:

Groom dried leaves until fall to maintain tidy appearance. In late winter or early spring, cut old stems to the ground before new growth emerges in spring. Divide plants regularly.

pests/diseases:

Powdery mildew and rust may occur.

controls:

Because the growing points of all grasses are in the crown (at ground level), cut stems to the ground to control heavy infestations of leaf diseases such as powdery mildew and rust.

how to sow/plant:

Choose a sunny site with moist, well-drained soil, and amend with well-rotted manure or compost. Set plants out in spring or fall at the same depth they grew in pot, spacing at a distance equal to their mature spread. Water after planting, and mulch to conserve moisture.

water and fertilize:

Maintain soil moisture all season. During active growth, apply an all-purpose fertilizer, following label directions.

garden hint:

When cutting down feather reed grass in late winter or early spring, tie the leaves together and cut all the growth from the base. This bundle will be easier to carry to the compost pile.
