Wild onion

Allium cernuum, commonly known as nodding onion, is a perennial bulbous herb of the family Amaryllidaceae (formerly Liliaceae or Alliaceae), native to a broad range of North America from southern Canada through the United States into northern Mexico, where it grows in open woodlands, prairies, rocky slopes and meadows. The plant arises from a narrow, elongate, conical, white-tunicate bulb 1.5–4 cm long, often clustered on a short rhizome. Several flat, grass-like, keeled basal leaves, 15–30 cm long and 2–6 mm wide, emerge each spring with a mild onion odour. The slender, smooth scape grows 20–60 cm tall and is distinctively bent or hooked downward just below the inflorescence, so the flower cluster nods rather than standing upright. The umbel is a loose, drooping cluster of 8–30 bell-shaped flowers, each 4–6 mm long, with six pink, rose or white tepals and exserted yellow stamens. Flowering occurs from June to August. The fruit is a three-lobed capsule containing several small, black seeds.
