Jack Bean: Chiang Dao
(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.

Local Thai variety with a bushy growth habit. Matures in 120 days.
