Charming Native Nodding Onion Plant
Add motion, color, and a touch of culinary heritage to your garden with the Nodding Onion (Allium cernuum). This graceful North American native features nodding clusters of soft lavender-pink flowers that sway gently in the summer breeze. An edible ornamental, this charming perennial bulb is both beautiful and useful, perfect for water-wise gardens and naturalized settings like rain gardens.
Each elegant stem holds an umbel of dangling, bell-shaped blooms loved by hummingbirds, bees, and butterflies. The long, grassy foliage ripples in the wind, adding texture and movement. Known also as Lady's Leek, Wild Onion, or Prairie Onion, this plant's soft hues and airy form create a lovely transition between wildflower borders and formal beds.
A plant with history and heart, the Nodding Onion was used by Native Americans for seasoning and medicine. Its bulbs and leaves have a strong, onion-like flavor, delicious raw in salads or cooked into savory dishes. Try harvesting a few bulbs, blanching, and freezing them for a flavorful Thanksgiving side! Just remember, a little goes a long way.
