Festuca idahoensis Elmer
Blue bunchgrass, Bunchgrass fescue, Idaho fescue
Poaceae (Grass Family)
Bunchgrass fescue or Idaho fescue is a modest-sized, cool-season bunchgrass with very narrow, leaves, often of a striking blue- to gray-green color. Grows in large tufts with flowers in narrow clusters on stiff stalks, flower stalks twice the height of the leaves. The flowering culms are 12-18 in. in height and rather insignificant. This is a perennial.
In spite of its rough leaves, Idaho Fescue is still an important native forage grass.
