There are three different types of peas:
English or Shell Peas:Â These peas are shelled which means that you don’t eat the shells or pods when mature.
Snap or Sugar Snap Peas:  Snap peas are smaller than English Peas. Also, the peas and the pods are edible. The pods are rounded and thicker than snow peas. Snap peas are a cross between English and Snow Peas.
Snow Peas: Like Snap Peas, the peas and pods are edible. The peas are very small and the pods are flat and thin. Â
Peas, Snap Peas and Snow Peas are in the Pod category and are members of the Legume Family.
