nodding wild onion

Allium cernuum (nodding wild onion), a native onion species, gets its common name from the growth habit of its scape (leafless flower stalk), which curves downward, giving the flower the appearance of nodding.

If the leaves of this plant are bent or bruised, they give off the familiar odor of onions. It’s no surprise then that the bulbs of nodding wild onion were once used in cooking.
