Jack Bean: ECHO Asia
(Canavalia ensiformis)
Canavalia ensiformis is native to the West Indies and Central America. It closely resembles Sword Bean, C. gladiata, and the predominantly African wild species, C. virosa. C. ensiformis is widely distributed in the tropics and subtropics although it is regarded as a minor vegetable rather than a major crop species.
A more aggressive climber than the local Thai variety.
