|discussion=<p><i>Heteropogon contortus</i> grows on rocky hills and canyons in the southern United States into Mexico, and worldwide in subtropical and tropical areas, occupying a variety of different habitats, including disturbed habitats. It is probably native to the eastern hemisphere but is now found in tropical and subtropical areas throughout the world.</p><!--
--><p><i>Heteropogon contortus</i> is a valuable forage grass if continuously grazed so as to prevent the calluses from developing. It is also considered a weed, being able to establish itself in newly disturbed and poor soils.</p>
