Nodding onion (Allium cernuum) produces a single flowering scape that terminates in an umbel of flowers. This umbel faces toward the ground because the scape bends downward at its apex. The small flowers may be white, light lavender, or pink. A flower consists of 3 petals and 3 sepals (i.e., tepals) with a similar appearance, and has 6 white stamens with yellow anthers. The blooming season is usually mid-summer and lasts about a month. There is no floral scent. The flowers are replaced by seed capsules containing small black seeds that are light in weight and rather flat. They are distributed to a limited extent by the wind.
