Description

Also known as big bluestem or turkeyfoot, A. gerardii is a native perennial graminoid that is a member of the Poaceae family. It is tufted, and contains short, scaly rhizomes. It is known for being a tall graminoid, ranging from 6 to 8 feet tall, and is very leafy at the basal region with some leaves that are carried up on the stem. As well, big bluestem contains rhizomes that are usually 1 to 2 inches below the soil surface for clonal reproduction [1].

Distribution

A. gerardii is distributed across the United States and Canada, but not past New Mexico or Montana [1].

Ecology

Habitat

Big bluestem can be found in prairies, open woods, along riverbanks, meadows, and even roadsides. It is particularly abundant in lowland prairies and sandy areas [1].

Phenology

A. gerardii flowers from August until October [2].

Use by animals

A. gerardii is utilized by birds and mammals for nesting and escape cover during the summer and winter, and contributes to the spring nesting habitats since it resists lodging under snow cover [1].

Conservation and Management

For management, A. gerardii has a considerably weak seedling compared to its competition, so control of its competition is necessary, such as high mowing for weed control or even grazing of competing cool season grasses before the big bluestem is 1 inch tall in the spring [1].

Cultivation and restoration

There are several cultivars available of A. gerardii, including 'Bison' (ND), 'Bonilla' (SD), 'Champ' (NE, IA), 'Kaw' (KS), 'Earl' (TX), 'Niagara' (NY), 'Pawnee' (NE), and 'Rountree' (IA) [1].
