Schizachyrium scoparium, commonly known as little bluestem or beard grass, is a species of North American prairie grass native to most of the contiguous United States (except California, Nevada, and Oregon) as well as a small area north of the Canada–US border and northern Mexico. It is most common in the Midwestern prairies.
Little bluestem is a perennial bunchgrass and is prominent in tallgrass prairie, along with big bluestem (Andropogon gerardi), indiangrass (Sorghastrum nutans) and switchgrass (Panicum virgatum). It is a warm-season species, meaning it employs the C4 photosynthetic pathway.
