Pole beans and bush beans are two varieties of beans, but there are a lot of differences between the two. One of the ways to differentiate between pole beans and bush beans is by comparing the farming space required when the two are growing.
Due to the method usually adopted when planting bush beans, they need more space, whereas pole beans don't need more space since they grow vertically. As a result of their pattern of growth, they need a pole for support, and maybe that is why they are called pole beans. The climatic need of these two varieties of beans is another differentiating factor.
While pole beans are planted in areas with cool weather, bush beans are grown in areas with hot weather. Out of the two, bush beans grow faster, and they are harvested at the same time. In contrast, the harvest of pole beans is done as they mature, meaning they are not harvested at the same time.
