Mesic to dry forests of sugar maple-red oak, sugar maple-beech, sugar maple-basswood, pine, pine-oak, aspen-pine, pine-birch, hemlock-pine-birch, hemlock-hardwoods, sugar maple-oak-pine, red maple-aspen, pine-hemlock, pine-white cedar-birch, fir-spruce-cedar; sometimes in bracken grasslands, pine barrens, and on cliff tops and rock outcrops. This is a very distinctive and early-blooming forest grass, forming clumps of evergreen basal leaves that are glaucous on the upper surface and dark green on the lower. However, the leaves are resupinate (like many forest grasses) so that it appears that the surfaces are reversed. Primarily found across the northern part of the state but extending southward along Lake Michigan and in the Driftless Area.
