The pomato (a portmanteau of potato and tomato), also known as a tomtato, is a hybrid plant that is able to grow both tomatoes and potatoes. The most common method of creating a pomato is grafting together a tomato plant and a potato plant, both of which are members of the Solanum genus in the Solanaceae (nightshade) family. Another method is somatically fusing the two plants together. Cherry tomatoes grow on the vine, while white potatoes grow in the soil from the same plant.
