There are many varieties of pea, all members of the legume family. Some like the English pea (the common garden pea) are grown to be eaten fresh, removed from their pods. Others, like the field pea, are grown specifically to be used dried. Pod peas are those that are eaten pod and all, namely, the snow pea and sugar snap pea.
