Andropogon gerardi Vitman. Big Bluestem, Turkeyfoot. Phen: Jul-Nov. Hab: In a wide variety of habitats, usually rather dry, such as longleaf pine sandhills, glades, cliffs, and rock outcrops, in the Piedmont in woodlands, former prairie-like sites, woodlands, open forests, and river-scour grasslands, in the Mountains in glades, riverside scour areas, and rarely in grassy balds, ascending to at least 1600 m over mafic rocks (on Old Field Bald, Watauga and Ashe counties, NC). Dist: QC west to SK, south to FL and AZ and Mexico.

Origin/Endemic status: Native

Taxonomy Comments: Some favor treating A. hallii Hackel as a subspecies of A. gerardi (Wipff 1996c); I do not agree, but if that course is followed, then our eastern taxon becomes A. gerardi ssp. gerardi.
