June Grass
Koeleria macrantha

a.k.a. Prairie Junegrass

June grass thrives on dry, well-drained/sandy soils. It is one of the few cool season native grasses, greening up in May with pale green ornamental flowering stalks in June. By mid-summer, the stalks turn tan and remain attractive throughout the growing season.
