Potatoes grow from seed tubers, not true seed. They originated in the Andes and come in a variety of types, colors and shapes.

Generally, there are russet types that are starchy with brown skins and that are good for baking; red potatoes that can have white, yellow, or red and starchy or waxy flesh; white potatoes with white or yellow flesh; purple colored potatoes; and fingerling types.

Potatoes need sunny locations to grow well.
