Nodding onion is a member of the Allium species and is the most common species in the Rocky Mountains. I've always loved the candy pink stripes and nodding heads on these wildflowers. Traditionally the bulbs were eaten either raw or cooked, used as flavoring for other foods, and dried for use in future meals. Bears and ground squirrels also enjoy these treats. The term 'allium' is Latin for garlic, which stems from the Celtic 'all' meaning 'hot' or 'burning' because of how onion irritates the eyes.
