Description: Unanimity reigns on the question of the good taste of sage and nuts with the fruity accents of its smooth and curved, semi-oval beans. Stringless beans are also highly prized when picked while young and eaten with the pod. The variable shape of the pods can be slightly to extremely curved, and their length can reach 20 cm. The beans contained in the pods are first ivory white before staining with beige and brown. Rattlesnake is a very old variety traditionally grown by the Hopi Indians of North America. The vines of this very productive selection grow vigorously, sometimes reaching 3 m in length.
