'''Nodding onion''' (''Allium cernuum''), also known as '''lady's leek''', is a perennial plant in the family [[Alliaceae]]. It has an unsheathed slender conic [[bulb]] which gradually tapers directly into several keeled [[grass]]-like leaves (2-4mm wide). Each mature bulb bears a single flowering stem, which terminates in a downward nodding [[umbel]] of white or rose [[flower]]s. Nodding onion blooms in July or August. The flowers mature into a spherical crested [[fruit]]s which later split open to reveal the dark shiny [[seed]]s. This plant does not have [[bulblet]]s. This plant grows in dry [[woods]], rock outcroppings, and [[prairie]]s. It is native to [[North America]] from [[New York]] to [[British Columbia]] south to [[Virginia]] and [[Kentucky]] and south in the [[mountain]]s. The bulb is edible and has a strong onion flavor.
This species is cultivated for its attractive flowers.
''Allium cernuum'' form ''major'' has larger plants and larger flowers than the normal species.
