Prairie blue-eyed grass blooming with wood betony at Crex Meadows in Wisconsin

Prairie blue-eyed grass is one of the more drought tolerant species in the genus. It blooms in late spring and early summer for about three weeks.[5] The flowers are white to pale blue, with yellow centers. They have six tepals 7 to 12.7 mm (0.28 to 0.50 in) long that have rounded ends with a sharp point in the center.[4] The flowers are borne on slender pedicels (stems) in an umbel enclosed in two bracts at the top of an unbranched flat stem. The leaves are grass-like, 3 to 10 inches (8 to 25 cm) long and 2 to 3 mm (0.08 to 0.12 in) across, and the flower stem is about as long as or a little longer than the leaves. The root system is coarse and fibrous. A plant produces offsets and forms a dense clump over time.[5]
