Lupinus concinnus

Lupinus concinnus, commonly called bajada lupine or elegant lupine, is a small annual herb in the Fabaceae family, native to the southwestern United States and northern Mexico. Plants grow 10 to 30 centimetres tall, with slender erect to ascending stems that are densely covered with long soft white hairs giving the foliage a distinctly silvery, woolly appearance. Leaves are alternate, long-petiolate, and palmately compound with 5 to 9 narrow oblanceolate leaflets, each 1 to 3 centimetres long and densely silky on both surfaces. Inflorescences are short, dense, terminal racemes 2 to 8 centimetres long, with whorled to scattered flowers. Each papilionaceous flower is 7 to 11 millimetres long with a violet to lavender standard marked with a paler central patch, lavender wings, and a deeper purple keel. Fruits are small hairy pods, 1 to 2 centimetres long, containing several smooth seeds. It grows on sandy slopes, washes, and open desert flats.
