Allium douglasii, commonly known as Douglas onion, is a perennial herb native to the grasslands and sagebrush deserts of the Pacific Northwest, specifically northeastern Oregon, eastern Washington, and northern Idaho. It flourishes at elevations between 1312-4265 feet (400-1300 meters), where it forms symbiotic relationships with the native fauna. The plant typically produces egg-shaped bulbs up to 1 inch long and scapes that can reach up to 16 inches tall. During the flowering season, which occurs in late spring to early summer, Douglas onion showcases umbels of showy pink or purple flowers that are highly attractive to pollinators such as bees and butterflies.

Douglas onion is valued for its ornamental flowers and its ability to adapt to dry, rocky soils, making it an excellent choice for rock gardens, native plant gardens, and xeriscaping. It requires minimal maintenance once established and is best grown in full sun with well-drained soil. While it is not commonly afflicted by diseases, overwatering can cause bulb rot. In culinary uses, the bulbs and leaves can be used similarly to common onions, adding a pungent flavor to dishes.CC BY-SA 4.0
