Origins and History – Blue Coco Pole Beans (Phaseolus vulgaris) are a striking French heirloom dating back to at least the late 18th century, treasured for their beauty, flavor, and productivity. Grown extensively in Europe before making their way to North America, they became popular with gardeners who valued both ornamental appeal and reliable yields. The name “Blue Coco” reflects their vivid hue and climbing habit, with “Coco” being a French term historically used for beans destined for drying.
Appearance and Characteristics – This variety produces vigorous climbing vines that can reach 6–10 feet, bearing clusters of deep purple-blue pods that shimmer in sunlight. Each slender, slightly curved pod grows to about 6–7 inches long, with tender green flesh beneath the skin. As the beans mature, the purple color fades during cooking, revealing a rich green. The seeds inside are small, tan to light brown, and oval-shaped. Plants are hardy, resilient, and highly ornamental, with attractive green leaves and delicate lavender-pink blossoms.
Culinary Uses – Blue Coco beans are a dual-purpose variety, enjoyed both fresh and dried. Young pods are tender and stringless, ideal for steaming, sautéing, or adding to salads, where their unique purple color offers visual flair. When dried, the beans have a mild, nutty flavor that pairs well with soups, stews, and casseroles. They are also a popular choice for French country cooking, where they are often used in hearty vegetable dishes and bean salads.
Growing Tips (Vegetation Zones and Sow Depth) – Suitable for USDA Zones 3–10, Blue Coco Pole Beans thrive in warm, sunny locations with well-drained soil. They require sturdy support such as poles, trellises, or netting to accommodate their tall, climbing growth. Direct sow seeds outdoors after the danger of frost has passed, planting 1 inch deep and spacing seeds 3–4 inches apart in rows or clusters at the base of supports. Keep soil evenly moist during germination and early growth. Like all beans, avoid high-nitrogen fertilizers, as these encourage excessive leaf growth at the expense of pods.
Harvesting Guidance – For fresh eating, harvest pods when they are young, firm, and about 6 inches long, before seeds swell noticeably. Frequent picking encourages continued production. For dried beans, allow pods to remain on the vine until they are fully mature, dry, and brittle, then shell and store the beans in a cool, dry place. A single planting can provide an extended harvest over the summer, making Blue Coco both a beautiful and practical addition to the garden.
