Cobra pole beans are slender, dark green beans known for their straight shape and crisp texture. They grow on climbing vines and are typically harvested when about six to eight inches long. The pods are tender and stringless, making them ideal for quick cooking methods like sautéing or steaming. Cobra beans retain their vibrant color and snap when cooked properly, adding both flavor and visual appeal to dishes. They are often favored for their high yields and extended harvest period throughout the growing season.
