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.
There are many different types of beans grown in Texas gardens, but the most common are green snap beans, lima beans, and the various types of horticultural beans. Green snap beans are usually of two types - bush or pole. However, bush beans are usually preferred over pole types due to the fact that they are earlier and produce a higher yield before the first killing frost. Bush beans generally require about 60 to 70 days of good growing conditions to produce a crop.
