Allium unifolium, the one-leaf onion or American garlic, [4] is a North American species of wild onion. It is native to the coastal mountain ranges of California, Oregon, and Baja California. [1] It grows on clay soils including serpentine, at elevations up to 1100 m. [5] [6]
Allium unifolium, despite its name, usually has 2–3 flat leaves up to 50 cm long. Bulbs, though, are usually solitary, egg-shaped, up to 2 cm long, often formed at the end of rhizomes spreading out from the parent plant. Scapes are round in cross-section, up to 80 cm tall. Flowers are up to 15 mm across; tepals usually pink but occasionally white; anthers yellow or purple. [5] [7] [8] [9]
This plant has gained the Royal Horticultural Society's Award of Garden Merit. [10]
