Pole beans (phaseolus vulgaris) are also called green, string, snap beans, or runner beans becauseâ

They require support as they produce long vines. Easily harvested. Traditionally grown on "tee-pee" framework of several long poles tied together at peak with 8-10 seeds planted at base of each pole. Can be planted in a row and grown on a trellis or along a fence. They bear over a longer period of time than bush beans.
