Koeleria macrantha (Prairie junegrass)
Bolin, Kathryn E.
This 1-2 ft., perennial bunchgrass bears dense, silvery green, spike-like seedheads which start growth very early in spring and turn tan by mid-summer. The leaves of June grass are gray-green.

Prairie Koelers Grass is a cool-season grass, dormant in late summer. On the Pacific coast there is a rather large, loosely tufted form with a more open seed head.
