(Setaria leucopila & vulpiseta)
Plains bristlegrass is a warm season perennial grass found throughout South Texas. It is found in a variety of soil types and successional stages, and can be especially prevalent on disturbed soils in the Rio Grande Plain. Identification of the specific species of bristlegrass is difficult to determine since hybridization likely occurs. Plains bristlegrass is considered good forage for cattle, and produces seed that is eaten by bobwhite quail and other birds. It produces seed several times per year. Germination varies because of poor seed fill. Plains bristlegrass should be planted in fall, late winter, or early spring. Production plots produce 214-369 pounds per acre dependant on seed size. Catarina is a South Texas release of this species that is now available for planting.
