Trionfo Violetto is an Italian pole bean that produces striking purple pods on vigorous vines, ready to harvest in 64 to 75 days. This heirloom variety thrives in full sun and moderate moisture, climbing steadily up a trellis or support structure. The beans develop their deepest color when grown in warm conditions, though gardeners in hot climates should time sowings carefully to avoid planting as temperatures approach 90°F consistently.

Purple pods stand out dramatically against the foliage, making this pole bean as ornamental as it is productive. The vines climb enthusiastically, turning a sunny spot into a living wall of beans that mature reliably within 10 weeks. Italian gardeners have long valued this variety for its consistent production and the striking color that deepens with sunlight exposure.
Fresh purple beans are typically harvested at a tender stage and eaten whole, either steamed, sautéed, or roasted. The striking color and firm texture make them a standout addition to fresh summer salads. As they mature, the pods can be left on the vine to dry for shelling fresh beans, extending the harvest season.
No timeline data available yet for this variety.
Sow outdoors 1 to 2 weeks after your average last frost date, when soil temperature reaches at least 65°F, ideally between 70°F and 85°F. Plant seeds 1 inch deep. For continuous harvests, make successive sowings every 7 to 14 days, stopping about 80 days before your average first fall frost date. In very hot summer areas, skip sowings as high heat approaches.
Pick pods when they reach tender, snap-stage maturity within the 64 to 75 day window. At this stage, the purple color is vibrant and the pods snap cleanly when bent. For shelling beans, allow pods to mature longer on the vine until they dry and rattle slightly when shaken.
