What are Runner Beans?

Runner beans (Phaseolus coccineus) are climbing legumes grown for their tender green pods and edible seeds. Unlike common green beans, runner beans have larger, flatter pods and a firmer texture. Young pods are harvested before they become fibrous and are cooked before eating.

Runner beans belong to the legume family and are rich in dietary fiber, vitamin C, vitamin K, folate, potassium, magnesium, and plant-based antioxidants.
