Herbaceous monocot. Stems cylindrical and tapering (terete). Leaves basal, grass-like, hairy. Petals and sepals 3, yellow, similar; stamens 6; ovary inferior; in umbelloid cymes of up to 3 flowers.
Flowers mid June to early October
Wetland indicator: Facultative wetland-
The leaves are almost indistinguishable from the surrounding grasses, impossible to find when it is not in bloom. The dainty little flowers add to the color of the prairies in spring.
A bit of a side note since I found some sources putting this in the Lily family. Plants in the Liliaceae are distinguished from similar families in having the ovary superior and a black seed coat. Plants in the Amaryllidaceae have the ovary inferior, a black or blue seed coat, and flowers in umbelloid cymes.
