The plant grows up to 2 m high.
It has simple ovate leaves, with wavy margins.
The flowers small, white coloured with purplish streaks and are like typical pea flowers but produced in dangling racemes within overlapping leaf-like bracts. The bracts are persistent and turn brown as the flowers mature.
The fruit is an edible bean. The beans explosively dehisce on maturity to release seeds. Seeds are brown-black with red spots.
The plant has medicinal uses in traditional medicine. Its root is used for treatment of epilepsy, hysteria and inducing sleep. The pounded root is also used to reduce fever. The leaves are used as a vermifuge for children.
The plant requires full sun and moderate water for growth.
