Ecological Benefits
Big Bluestem (Andropogon gerardii) is a native warm-season grass that once dominated the tallgrass prairies of North America and remains an important component of Maryland grassland ecosystems. Its dense root system helps stabilize soil, improve water infiltration, and support healthy soil structure.
 
This grass provides valuable cover and nesting habitat for birds and other wildlife, while its seeds offer food sources throughout the year. Big Bluestem also supports numerous native insects and contributes to the biodiversity and resilience of meadow and prairie plantings.
