How Many Types of Beans are There?
While there are far too many specific bean types to name, the majority of bean plant varieties can be divided into a few main subgroups. One very big distinction is between pole beans and bush beans. Pole beans are vining and need a structure to climb up, like a trellis or a fence. Some varieties can get quite long. However, these plants offer the added advantage of a small footprint; so, if your space is limited, any vegetable that can be grown vertically and still produce high yields is a great choice. Bush beans, on the other hand, are shorter and freestanding. Since they can be planted virtually anywhere, bush beans are easier to grow. Another thing that divides the varieties of bean plants is the difference between snap beans and shell beans. Basically, snap beans can be eaten raw, pod and all, while shell beans are meant to be opened up, or shelled, so the seeds inside can be eaten, and the pods thrown away. Snap beans may include green beans, yellow beans, and peas (which can also be shelled). Examples of shell beans include:
Lima Navy Pinto Kidney Black-eyed pea
Really, most beans can be eaten pod and all if they’re immature enough, and most beans will have to be shelled if they’re allowed to mature or even dry out. Different varieties of bean plants are bred for both, however, which means that a bean marketed as a snap bean will taste much better raw than one marketed as a shell bean.
