Among the more than 1,000 varieties of garden pea, the most common are smooth peas, the type generally sold frozen, and the wrinkled variety, which is generally tinned. Other varieties include the sugar snap pea and snow pea, both of which have edible pods. Beyond the garden pea varieties are the grey or field pea, primarily used as fodder crop, and the wild Mediterranean pea sometimes called the oasis or maquis pea. Dried peas are available whole or split, and are either green or yellow.
