Southwestern Bristlegrass (Setaria scheelei): A Delicate, Native Bunchgrass of Arid Regions

Southwestern Bristlegrass, Setaria scheelei, is a perennial bunchgrass native to the southwestern U.S. and northern Mexico. It is a component of desert grasslands and oak savannas.

Subtle Charm

This grass forms small, dense tufts 1–2 feet tall. The leaves are narrow, often curling. The inflorescence is a narrow, cylindrical, bristly spike (typical of Setaria) that emerges in summer, greenish to purplish. The bristles are retrorsely barbed, aiding seed dispersal.

Ecological Role

It provides forage for wildlife and livestock. It thrives in well-drained, rocky or sandy soils in full sun. Drought-tolerant. A modest but important native grass for arid land restoration and naturalistic plantings.
