Sophora stenophylla, the fringeleaf necklacepod, or silvery sophora, is a perennial plant in the legume family (Fabaceae) found in the Colorado Plateau and Canyonlands region of the southwestern United States.[1]
It is a perennial plant that grows 4to tall. Its lacy leaves and blue to purple flowers make it very distinctive in its communities. It spreads by underground roots.[2]
It has alternate, lacy, compound pinnate leaves with linear leaflets that are covered in dense, soft, and silvery hairs.
It blooms from April to May.[1] The terminal stalks bear 12–39 blue to purple, pea-shaped flowers. Seed pods have short, stiff hairs and 1–5 seeds.
It can be found in sandy soils in blackbrush scrub, pinyon-juniper woodland, and ponderosa pine forest communities in southern Utah, Arizona, and New Mexico.
Its foliage and seeds are toxic to livestock in large amounts.
