Newberry’s Milkvetch

Astragalus newberryi var. newberryi, commonly known as Newberry’s Milkvetch, is a perennial herbaceous plant native to the western United States, particularly found in regions such as eastern California, Nevada, and parts of Utah. This variety typically grows in arid to semi-arid environments, often in sandy or gravelly soils at elevations ranging from 1,500 to 3,500 meters. The growth habit of Newberry’s Milkvetch is characterized by a low, spreading form, usually reaching heights of 20 to 50 centimeters. The plant may develop a dense mat of foliage, which helps it to conserve moisture and withstand drought conditions.

The leaves of Astragalus newberryi var. newberryi are pinnately compound, generally comprising numerous small leaflets that are lanceolate to ovate in shape, providing a feathery appearance. The flowers, which bloom in late spring to early summer, are typically purple to violet and are arranged in clusters, attracting various pollinators, including bees. The fruit is a legume, which develops into a flattened pod that contains several seeds. These pods are often hairy and can be slightly curved, aiding in seed dispersal. Newberry’s Milkvetch plays an important ecological role as a nitrogen-fixing plant, enhancing soil fertility and contributing to the overall health of its native habitat. Additionally, it is utilized in some restoration projects and as forage for livestock, showcasing its value in both ecological and agricultural contexts. Adaptations such as deep taproots allow the plant to access water from deeper soil layers, making it well-suited for survival in its arid native range.
