how tall do green bean plants grow
Pole beans are the tallest of the green bean plants. They grow between 5 to 10 feet long, depending on the variety. To keep the beans from rotting, pole beans are always grown vertically, rather than allowed to sprawl.t 1 to 3 feet tall, bush-style green beans don't require a support structure. Because they are almost as wide as they are tall, even those close to 3 feet aren't in danger of toppling.
