nodding onion

Allium cernuum

The nodding onion is a pretty flower that grows in clusters. Its delicate pink blooms hang down like little bells, and it has a lovely oniony smell when you touch it!

Habitat: Grasslands

Appearance

The nodding onion has slender, grass-like leaves and stems that hold bell-shaped clusters of pink to white flowers. These flower clusters gracefully droop downwards, giving the plant its distinctive 'nodding' appearance.
