Allium amplectens is a species of wild onion known by the common name narrowleaf onion. It is native to British Columbia, Oregon, Washington State and California, where it grows in woods and especially in clay and serpentine soils. Allium amplectens grows from a pinkish-brown bulb and sends up a naked green stem topped with an inflorescence. When closed, the inflorescence is wrapped in bright pink to magenta bracts. These open to produce between 10 and 50 shiny white to pale pink flowers, each under a centimeter wide. The six stout stamens and the ovary are white or tinted pink or lavender.
