Butter beans (Phaseolus lunatus), also known as Lima beans, are medium- to large-sized, white kidney-shaped beans, and grown like a runner bean on supports or wigwams. A good source of dietary fibre, and a virtually fat-free source of high-quality protein, 'Fagiolo Di Spagna' is a heritage variety of shelling bean with approximately 3-5 beans per flat, green pod which reach 15cm (6”) in length. They can be cooked like a French bean if picked when young. Cooked prior to eating, they are excellent in soups or a summer bean salad, and the plant benefits the entire plot by fixing nitrogen in the soil.
