So how big do bean plants get anyway? With plenty of space in the garden at first I didn't really care. But now I have shadows to worry about ruining the sunshine other plants need, or do I? Some bush beans get only a little over 2' while pole beans can grow up to 10 feet tall! Ten feet tall is a LOT of shadow to worry about, 2 feet, not so much. I think I'll keep the pole beans at the edges of the garden but be a little brave about placements for the bush beans. Wondering about beans? See The Tall and the Short of It: Beans at Dave's Garden.
The Farmer's Almanac http://www.almanac.com/plant/beans has greatly helpful information about beans, too!
