Allium amplectens, the narrowleaf onion, is a species of flowering plant. It is a onion native to the west coast of the United States, in Oregon, Washington State and California, also British Columbia in Canada. It grows in woods and especially in clay and serpentine soils.[2][3]


Growing to 50 cm (20 in) tall and broad, this herbaceous perennial[4] grows from a pinkish-brown bulb and sends up a naked green stem topped with an inflorescence wrapped in bright pink or magenta bracts. These open to produce between 10 and 50 shiny white or pale pink flowers, each under a centimeter wide. The six stout stamens and the ovary are white or tinted pink or lavender.[3][5][6][7]

Cultivars include 'Graceful'.[4]
