About Narrow Leaved Onion (Allium amplectens) Allium amplectens is a species of wild onion known by the common name narrowleaf onion. It is native to western North America where it grows in woods and especially in clay and serpentine soils. It grows from a pinkish-brown bulb and sends up a naked green stem topped with an flower cluster. When closed the flower cluster is wrapped in bright pink to magenta leafs. It opens 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. It is a fairly widespread species.
