Also known as: Howell's Onion

Allium howellii var. howellii, commonly known as Howell’s Onion, is a perennial herbaceous plant native to the western United States, particularly found in the states of Oregon and California. This species typically inhabits open grasslands and rocky slopes, thriving in well-drained soils at elevations ranging from 1,000 to 2,500 meters. The growth habit of Howell’s Onion is characterized by its upright form, reaching a height of approximately 30 to 70 centimeters. The plant forms a clump of narrow, linear leaves that can be up to 30 centimeters long, which are often glaucous or bluish-green in color, providing a striking contrast to the flowering stalks.

The inflorescence of Allium howellii var. howellii is a characteristic umbel, consisting of numerous small, star-shaped flowers that bloom in shades of pale pink to white. Each flower typically measures around 1 to 2 centimeters in diameter and is supported by slender pedicels. The flowering period generally occurs from late spring to early summer, attracting various pollinators such as bees and butterflies. Following the flowering phase, the plant produces small, bulbous fruits known as capsules, which contain seeds that can be dispersed by wind or animals. Howell’s Onion plays a significant ecological role in its native habitat, contributing to the local biodiversity and serving as a food source for various herbivorous animals.

In addition to its ecological significance, Howell’s Onion has been utilized by Indigenous peoples for its edible bulbs, which can be consumed raw or cooked. The plant’s bulbous structure allows it to store energy and survive in its native habitat, showcasing an adaptation to its environment. The ability to thrive in nutrient-poor soils and withstand periods of drought further enhances its resilience, making Allium howellii var. howellii a notable species within its ecosystem.
