|discussion=<p><i>Festuca idahoensis</i> grows in grasslands, open forests, and sagebrush meadow communities, mostly east of the Cascade Mountains, from southern British Columbia eastward to southwestern Saskatchewan and southward to central California and New Mexico. It extends up to 3000 m in the southern part of its range. It is often a dominant plant, and provides good forage. The young foliage is particularly palatable.</p><!--
--><p><i>Festuca idahoensis</i> differs from <i>F. arizonica</i> (see previous), with which it is sometimes confused, in its less prominently ribbed blades and glabrous ovary apices. It has frequently been included in <i>F. ovina</i> (p. 422).</p>
