Summary
Allium amplectens, commonly known as Narrowleaf Onion, is a deciduous perennial herb native to a variety of habitats including open woodlands, chaparral, and grasslands in the Western United States, particularly in California and Oregon. It typically grows to 50 cm (20 in) tall and broad. The plant emerges from a pinkish-brown bulb and features a naked green stem that culminates in an inflorescence enveloped in bright pink or magenta bracts. These bracts open to reveal a cluster of 10 to 50 shiny white or pale pink flowers, each less than a centimeter wide, with six stout stamens and an ovary that are white or tinted pink or lavender. The flowering season occurs in late spring to early summer, and the flowers are moderately showy, attracting pollinators such as bees.
Narrowleaf Onion is appreciated for its ornamental flowers and is often used in rock gardens, borders, and naturalized areas. It is also valued for its culinary uses, as the bulbs and flowers are edible. This plant is relatively low-maintenance, requiring full sun and medium amounts of water. It thrives in well-drained soils and is tolerant of a range of soil types, from sandy to loamy. While it is not commonly afflicted by diseases, onion thrips and onion maggots can sometimes be problematic. It is not known to be invasive and can be propagated by seed or division of the bulbs.CC BY-SA 4.0
