Trionfo Violetto' translates to "purple triumph", and this Italian heirloom will surely win you over with its thin, crisp, flavorful purple pods. Highly ornamental, plants climb 6'–8', and have abundant lavender flowers that bloom against lush green leaves with purple veins and stems; you'll be harvesting beans until late summer. Like other purple beans, the pods magically turn green when cooked!
• Botanical Name: Phaseolus vulgaris
• Days to Maturity: 64–75 days
• Family: Fabaceae
• Native: Mexico and South America
• Hardiness: Frost-sensitive annual
• Plant Dimensions: 6'–8' vigorous vines
• Variety Information: 6"–8" long, thin, deep purple, stringless when young, oval-round pods with tan seeds. Beans turn green when cooked.
• Type: Snap bean
• When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 65°F, ideally 70°–85°F. Successive Sowings: Every 7 to 14 days up to 80 days before your average first fall frost date. NOTE: In very hot summer areas, skip sowing as high heat approaches; temperatures consistently above 90°F will prevent beans from forming.
• When to Start Inside: Not recommended; bean seedlings are sensitive to root disturbance.
• Days to Emerge: 6–12 days
• Seed Depth: 1"
• Seed Spacing: 1 seed every 6"
• Row Spacing: 36"
• Thinning: Not required
• Harvesting: Snap beans are ready to pick when the pod "snaps" or breaks in half cleanly. This is when seeds have just begun to form and the pods are several inches long (depending on the variety). Hold stem with one hand and the pod with the other hand to avoid pulling off branches, which will continue to produce. Harvesting early and often will stimulate flower production for more beans. At season's end, plants are great compost material if they are disease-free.
