Eragrostis spectabilis is native in the eastern portion of the Flora region, extending from southern Canada through the United States, Mexico, and Central America to Belize. It grows in fields and on the margins of woods, along roadsides, and in other disturbed sites, usually in sandy to clay loam soils, at 0-1830 m, and is associated with hardwood forests, Prosopsis-Acacia grasslands, and shortgrass prairies. A showy species, E. spectabilis is available commercially for planting as an ornamental.
