Many-branched perennial; the branches lie on the ground but their ends ascend. Flowers in umbels, terminal, with the typical configuration of pea flowers, bright golden yellow. Blooms May–September. Leaves compound, with 3 leaflets (a terminal and 2 opposite) some distance below. Two basal leaves are actually stipules, not technically part of the compound leaf, but added to the true leaflets it looks like there are 5 total leaflets. All are variably oblong. Fruits are beaked, slender, upright pods bearing 5-14 seeds.
