Ruby Moon Hyacinth Bean Vine is a frost-tender climbing legume that transforms summer gardens with deep purple pods and ornamental foliage. This cultivar of Lablab purpureus thrives in warm conditions, producing tender beans ideal for fresh eating or cooking. Plant it after your last frost date when soil reaches 65°F, and watch it climb a trellis while delivering both beauty and harvest through late summer.

Deep purple pods emerge from equally striking purple flowers, making this vine as ornamental as it is productive. The beans themselves are tender and flavorful when harvested young, and the vigorous vining habit means a single planting provides weeks of picking. In warm climates, this variety genuinely loves heat and actually produces better when temperatures stay consistently warm, unlike many beans that shut down in peak summer.
The young, tender pods are harvested and cooked fresh, similar to snap beans or okra. They can be steamed, stir-fried, or added to curries and vegetable dishes. The mature dried beans are also edible and nutrient-dense, making this a dual-purpose crop depending on when you choose to harvest.

Sow directly outside 1 to 2 weeks after your average last frost date, once soil temperature reaches at least 65°F (ideally 70°F to 85°F). For continuous harvests, make successive sowings every 7 to 14 days until 80 days before your average first fall frost date. In very hot summer areas, skip sowing once temperatures approach 90°F consistently, as the heat will prevent pods from forming.
Pick pods when they are young and tender, before they become tough or fully mature. Regular harvesting encourages continued production throughout the season. If you prefer to save mature beans for drying, allow pods to fully mature on the vine until they turn dark and harden.
