This week on We Dig Plants Alice and Carmen discuss "The Three Sisters": corn, beans, and squash. These crops actually produce the highest yield when planted and grown together, and have been planted as such by Native Americans who passed knowledge of the sisters on to early American settlers. This trio also provides a very complete nutritional picture, with the corn providing carbs, the beans protein, and the squash fats an vitamins. Learn about the rich history of these sister veggies with tales of beans-as-currency, and peer at their potential hybridized future. This episode was sponsored by Whole Foods Market.
