Some leaves grow on the upper branches; these are generally made up of a single leaflet.

Each leaflet is under a centimeter long and may be linear to oblong in shape and coated in soft silvery hairs.

The white, pea-like flower is up to a centimeter long and is often marked with a dark pinkish streak near the base.

The pods turn black with age and dehisce explosively to release their four to six seeds away from the parent plant.

It is still sometimes grown and sold for landscaping purposes despite its status as a pest plant, with new industry and public education programs resulting.
