Jack Bean IntroductionCultivation InstructionsSeed Saving Instructions
Originating in Central and South America, and grown in the southwestern US as far back as 700 AD. Used as food, forage, ground cover, weed suppressant, even as a coffee substitute. Toxicity in mature beans requires cooking before eating. Plant 1 inch deep when soil has warmed. Water well until established. Requires a long growing season, 150 days or more. Tie vines to support or will sprawl. Frost sensitive but grows semi-perennially in warm areas.Let seed pods dry on plant. If pods become too dry they can split and fling seeds, so harvest often or bag pods to catch seeds.
