Vine Coastal jack-bean is a trailing,
herbaceous vine that forms mats of foliage. Stems reach a length of more than and in thickness. Each compound leaf is made up of three leaflets in diameter, which will fold themselves when exposed to hot sunlight. It is highly
salt-tolerant and prefers
sandy soils.
Flowers and pods The flowers are purplish pink and long, they hang upside down from long stalks and produce a sweet smell. The flat pods are straight or a little curved, long, their skin becoming prominently ridged as they mature. Each pod has between 2–10 brown seeds. The seeds are buoyant so they can be
distributed by ocean currents. The plant seems to contain
L-Betonicine. The Canavalia rosea plant fruits and blooms all year long. File:Canavalia rosea MHNT.BOT.2016.24.55.jpg|
