Nodding Onion

Allium cernuum
Amaryllidaceae

Growth Habit

Geophyte

Propagation

Seed Treatment and Storage: easy to grow and a prolific germinator, but seed is only viable for one year

Biocultural Value

Native American groups throughout nodding onion's range have employed the plant's spicy bulbs and leaves as a vegetable and flavoring. The Cherokee also used the juice to treat colds, sore throats, hives, kidney problems, and liver complaints. The Cherokee, Isleta, Kwakiutl, and Quinault prepared a poultice of the bulbs and applied it to various parts of the body to ease fevers, croup, skin infections, sores, and pleurisy.

Wildlife Value

Cellophane bees (Colletes spp.) are one of nodding onion's principal pollinators and visit the flowers for both pollen and nectar. Additional floral visitors include leafcutter bees (Megachile spp.), small resin bees (Heriades spp.), sweat bees (Lasioglossum spp.), bumble bees (Bombus spp.), soldier beetles (Chauliognathus spp.), tumbling flower beetles (Mordella spp.), and syrphid flies (Allograpta spp.)
