Pole beans are a type of climbing bean that grow vertically, using structures like trellises or poles for support. They belong to the Phaseolus vulgaris species and are known for their long, slender pods. These beans are typically harvested when young and tender, making them a popular choice for home gardens. Growing pole beans can be beneficial as they produce a high yield in a small space. They are also known for their ability to fix nitrogen in the soil, which can improve soil health. Common varieties include Kentucky Wonder and Blue Lake, each offering unique flavors and textures.
