Andropogon gerardii

Native Herbaceous PerennialUsed for erosion control in sand and gravel pits, mine spoils and roadsides; contributes to diversified biomass production; a high-quality livestock forage; provides food and cover for wildlife.

Big-BluestemBig Bluestem, Andropogon gerardii, is one of the more predominant species in the North American tallgrass prairie ecosystem. Native to North America, this perennial, warm season grass is tolerant of a wide range of soil conditions and moisture levels. Big Bluestem produces a significant amount of biomass and is gaining attention as a potential feedstock for alternative fuels and fiber, including pellets and cellulosic ethanol. When managed for biomass pellet feedstock or other applications requiring dry matter, Big Bluestem should be mowed in the fall to minimize dry matter loss, as it has little ability to stand over the winter in many areas. Some research has shown Big Bluestem to consistently have lower ash than other dedicated energy crops.
