Similar species (if any): Allium stellatum (Prairie Onion) is similar. The latter can be distinguised from Allium cernuum by the more nodding character of the inflorescences for A. cernuum, but A. stellatum can also display this characteristic for plants that are not mature. A. stellatum has a spreading and open perianth (non-reproductive parts of the flower), whereas the perianth of A. cernuum is mostly bell-shaped. In Wisconsin, A. stellatum is a more northern distributed species, and A. cernuum is a more southern distributed species.
Ethnobotany: This plant was widely used by at least 23 Native American tribes including the Chippewa (Smith, p. 406, 1932) as a food source, both cooked and eaten raw. Several tribes used the plant as either a cold remedy, dermatological aid, gastrointesinal aid, or pulmonary aid (Moerman, p. 57, 1998).
