This beautiful, old heirloom variety is good for fresh use or for dried beans. When the flat, string-less 15-18cm (6-7") beans turn from a lime green to yellow with bright purple stripes, they're ready to use for cooking or freezing. They can also be grown to the dry stage for winter use in soups and stews. You should mark some plants for regular picking and leave other plants unpicked to mature for dry beans. Dragon tongue bush bean seeds are brown with dark markings. Also known as Merveille de Piemonte.
