Allium douglasii, the Douglas onion, is a plant species native to northeastern Oregon, eastern Washington, and northern Idaho. It grows in shallow soils at elevations of 400–1,300 m (1,300–4,300 ft).[1][2]

Allium douglasii produces egg-shaped bulbs up to 3 cm (1+1⁄4 in) long. Scapes are round in cross-section, up to 40 cm (16 in) tall. Flowers are up to 10 mm (3⁄8 in) across; tepals pink or purple with green midribs; anthers blue; pollen white or light gray.[1][3][4][5] Two grooved leaves usually remain during the flowering stage.[6]
