Description
editVine
editCoastal jack-bean is a trailing, herbaceous vine that forms mats of foliage. Stems reach a length of more than 6 m (20 ft) and 2.5 cm (0.98 in) in thickness. Each compound leaf is made up of three leaflets 3.0–15.0 cm (1.2–5.9 in) in diameter, which will fold themselves when exposed to hot sunlight.[2] It is highly salt-tolerant and prefers sandy soils.[6]
Flowers and pods
editThe flowers are purplish pink and 2.5–5.1 cm (0.98–2.01 in) long, they hang upside down from long stalks and produce a sweet smell.[2] The flat pods are straight or a little curved 6.0–15.2 cm (2.4–6.0 in) long, their skin become 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.[6] The plant seems to contain L-Betonicine.[citation needed] The Canavalia rosea plant fruits and blooms all year long[1].
