Pole Beans. Pole beans grow to heights of 10 feet or more and require staking. Many prefer the increased size and rich flavor of pole beans to that of bush beans. However, they require more time to reach maturity. Pole beans, such as Kentucky Wonder and Kentucky Blue, produce tender green pods that mature in 65 to 75 days. Half-runner beans, such as Mountaineer and Mountaineer White, reach a height of approximately 3 feet and benefit from trellising. These green beans are a cross between bush beans and pole beans.
Pole beans are beans which are bred to grow in the form of vines which cling to poles or trellises. Their growth habit makes them very easy to harvest, and many commercial bean producers grow pole beans for this very reason. These beans are also very easy to grow at home, as long as you live in a temperate to warm climate.
