Does this plant grow in a vine, have a blue flower, purple seed pods and the leaves appear somewhat purplish?
Oh, you got me! Thomas Jefferson introduced Hyacinth Bean to America. THAT'S the plant he grew, not Castor Bean. I posted that this morning before I had my second cup of coffee. My bad. :)
And yes, Hyacinth Bean grows just like a pole green bean, but has purplish heart-shaped leaves and gorgeous pinkish blossoms. People use it as a decorative vine inthe garden. The Hyacinth Bean seeds can be eaten, but they're the ones that need to be rinsed and boiled, rinsed and boiled before eating.
Sorry if I confused anyone. People DON'T generally eat Castor Beans. Again, my mistake!
