Little Bluestem


Order: Cyperales
Family: Poaceae
Genus: Schizachyrium
Species: S. scoparium

Identifying Characteristics:

-This native perennial grass is 2-3' tall and tufted at the base. The culms are tan or reddish brown, hairless, and terete; the base of each culm is erect, rather than decumbent across the ground.
Alternate leaves are produced primarily along the lower half of each culm. The leaf blades are up to 10long and ¼" across, light green or light blue, hairless or slightly pubescent, and curling outward. The leaf sheaths are light green or light blue, hairless or slightly pubescent, and finely ribbed.


Special Adaptations:

-The preference is full sun and mesic to dry conditions. Different kinds of soil are tolerated, including those that contain clay-loam, gravel, or sand. Less fertile soil is preferred because of the reduced competition from taller vegetation. Because of its C4 metabolism, Little Bluestem develops primarily during the warm weather of summer and early fall, and it has excellent drought resistance.

- Habitats include hill prairies, gravel prairies, sand prairies, black soil prairies, clay prairies, scrubby barrens, rocky slopes of thinly wooded bluffs, sandy savannas, hilltop glades (limestone, sandstone, or shale), sand dunes, gravelly areas along railroads, and abandoned fields.

-Little Bluestem is often used in prairie restorations and it is occasionally found in gardens as an ornamental grass. In Illinois, this is one of the dominant grasses of hill prairies
