Trionfo Violetto translates from Italian as “purple triumph,” which aptly describes this pole bean. Vines bear lavender flowers, green leaves with purple veins and stems and 7- to 10-inch purple bean pods. Plants bear heavily. Vines are ornamental and easily fit into non-food production areas. Whether you’re feeding a family or putting up for winter eating, you’ll have more than enough beans when you plant 'Trionfo Violetto'. Beans turn green when cooked.
