A. virgata is a perennial graminoid of the Poaceae family native to North America.  It is a tufted perennial reaching up to 1 m tall, with glabrous sheaths that can be longer or shorter than the internodes. Leaf blades flat to curling, panicles narrow with loosely to densely arranged flowers. Central awn is reflexed and twice as thick at the lateral awns.
A. virgata can be found in the southeastern United States from Texas to New York. 
A. virgata proliferates in moist to wet pine savannas, wet pine flatwoods, mountain bogs, and other moist habitats.  Specimens have been collected from open pine savanna near a marsh edge.  In Florida, A. virgata has been found to be frequent in the communities it is found.
A. virgata does not hold up well against transplanting. 
A. virgata flourishes when the following burning treatments are applied: periodic summer and annual winter.
