|discussion=<p><i>Hordeum jubatum</i> grows in meadows and prairies around riverbeds and seasonal lakes, often in saline habitats, and along roadsides and in other disturbed sites. It is native from eastern Siberia through most of North America to Mexico, growing at elevations of 0-3000 m. It has been introduced to South America, Europe, and central Asia. It is grown in Russia and other areas outside its native range as an ornamental. In its native range, it is a weedy species.</p><!--
--><p><i>Hordeum jubatum</i> shows a wide range of variation in almost all characters; most such variation is not taxonomically significant. <i>Hordeum jubatum </i>subsp.<i> intermedium</i> is considered to be a subspecies of <i>H. jubatum</i> because no clear-cut discontinuities exist in the characters used to distinguish it from <i>H. jubatum </i>subsp.<i> jubatum</i>. These plants are fertile.</p>
