Solanum tuberosum is a perennial plant in the nightshade family, Solanaceae. Commonly known as potato after its starchy, underground storage organs which are consumed as vegetables worldwide. Potatoes are tuberous plants with edible underground storage organs. They are oval to round or irregularly shaped with smooth skin. The tubers are pale yellow, creamy whites, purples or pinks and suitable for cooking or crisping.
