Jack Bean
Jack Bean is native to the West Indies and Central America. It closely resembles Sword Bean, Canavalia gladiata, and the predominantly African wild species, Canavalia virosa. Jack Bean now is widely distributed in the tropics and subtropics although it is regarded as a minor vegetable rather than a major crop species.
Uses
Jack Bean is succeeding as a green manure/cover crop plant because its deep root system can find water during drought and its nitrogen fixation capabilities improve soil nutrients. Jack Bean can be interplanted with cacao, citrus, coconut, pineapple and tobacco. It can also be used as supplementary food for ruminant (cud-chewing) animals, especially if the plant material is dried before it is fed. Jack Bean forage should be introduced gradually as a small percentage of the total diet because of toxins in all plant material. Asians eat the young green pods and seeds but only after thorough cooking. There is some evidence from Colombia that a quantity of fresh Jack Bean leaves placed three nights consecutively on leaf-cutting ant colonies were totally consumed and destroyed the colonies.

19-03-1999 This is a good example of how quickly seeds can multiply. “Of the 8 seeds that were sent 4 were planted in a placewhere sunlight was restricted to about 4 hours a day. These gave very few pods. The 4 others got more sunlight and we got a harvest of 185 seeds so far. We have planted 160 of these...
