Native Tall Grass Prairie

LITTLE BLUESTEM
(Schizachyrium scoparium)

Description

While traveling along the road, have you ever wondered what the bunches of red grass are along many ridges and slopes? This grass could be little bluestem. The scientific name scoparium comes from a Greek word meaning broom-like, referring to the stiffly bunched stems. Little bluestem grows to a height of 1 to 4 feet (0.3 m to 1.2 m). The flat, hairless leaves of this species turn bluish-green to reddish-brown at maturity. The seeds are fluffy white by the end of the growing season. 


Species Distribution
Distribution

Little bluestem is native to North American tall grass prairies although it can be found throughout South Dakota along ridges and in sandy soils. It is most abundant in the Black Hills and the remnant areas of tall grass prairie in the eastern part of the state. Wherever it is found, little bluestem is one of the dominant species in the area. 

Natural History
 

Little bluestem is a bunchgrass that reproduces only by seeds. It is a warm season species that starts to grow in late spring, with the seedhead developing and maturing in August. Little bluestem is a perennial that produces several stems from one set of fine, fibrous roots that serve to store food and hold the plant in the soil. Because little bluestem becomes coarse at the end of its growing season, it is often burned to enhance its nutritional quality. Burning releases nutrients, making them available for new plant growth.

Significance
 

Domestic and wild animals prefer to eat little bluestem when the plant is very young and green. After it has matured and reached the end of its growing season, the plant is very coarse and animals will not eat it. Little bluestem makes fine hay, but consecutive years of haying will cause it to disappear from the area.
