|discussion=<p><i>Bouteloua gracilis</i> grows in pure stands in mixed prairie associations and disturbed habitats, usually on rocky or clay soils and mainly at elevations of 300-3000 m. Its native range extends from Canada to central Mexico; records from the eastern portion of the Flora represent introductions.</p><!--
--><p><i>Bouteloua gracilis</i> is an important native forage species and also an attractive ornamental.</p>
