Nodding onion is the most widespread species of native Allium in North America. It's one of the least objectionable of our native onions, and has fed very many Indians and pioneers. The Native Amarican Ethnobotany Database lists 28 tribes that have used it. Nodding onions, particularly the juice, also found milder medical uses. They grow in open woods and prairies in AL, AR, AZ, CO, IA(T), ID, IL, IN, MD, MI, MN(T), MO, MS, MT, NC, NE, NM, NY(T), OH, OR, PA, SC, SD, TN, TX, UT, VA, WA, WI, WV, WY, AB, BC, ON, and SK.
