Grows 2 to 3.5 feet tall, sometimes branching in the upper half. The stems are light green and usually hairless. Alternate compound leaves occur at intervals along the stems; they are trifoliate and their leaflets are extended horizontally in relation to the ground. The leaflets are elliptic to oblong in shape and smooth along their margins. The branches of each inflorescence are light green and covered with hooked hairs. Individual flowers are 0.25 inch long (or a little more), consisting of 5 petals, a short tubular calyx with teeth, an ovary with a single style, and several hidden stamens. The flowers have a typical pea-like structure, consisting of an upright banner and 2 lateral wings that enclose a central keel. The petals are pink to rosy pink; at the base of the upper petal (banner), there are 1 to 2 tiny patches of yellow. The green calyx is covered with hooked hairs. The slender petioles of the flowers are about 0.5 inch long; they are green to reddish purple and also covered with hooked hairs.
