Feather Reed Grass

Revered around the world as one of the showiest, easiest grasses to grow; people ask for it by name. Green foliage forms a narrow, upright clump topped with numerous inflorescences early in the season that age to wheat-like seed heads in fall. This cool season grass makes a fantastic hedge or screen.

Grower Information

Ornamental grasses and grasslike plants vary widely by type. Cool season grasses are generally best planted in the fall prior or in late winter/early spring in the greenhouse. Warm season grasses can be planted in spring and summer for same-season sales. Sedges grow best when planted in spring and summer rather than the fall prior.

Ornamental grasses and grasslike plants grow well in a wide range of growing media types, provided there is adequate moisture-holding capacity and good drainage. While getting established in their finished containers, most prefer to be kept moist, but not saturated.
