Allium cernuum

Commonly called wild nodding onion, this allium is native to much of the United States. The sweet little flower clusters - ranging in color from white to pink - droop down from their stems, hence the common name. Nodding onion is edible and has medicinal uses similar to garlic.

Fun fact: The city of Chicago gets its name from the Algonquin Indian name for this plant, "chigagou".
