Just so, are purple potatoes natural?
Purple potatoes, also known as Peruvian purple potatoes, have naturally purple or deep blue skin and flesh, and are unusually high in antioxidants which makes them super healthful.
Accordingly, did potatoes used to be purple?
It turns out that these purple (sometimes deep-blue) potatoes are actually from Peru and Bolivia in South America. Purple potatoes were first transported to Europe in the 1500's, when Spanish sailors realized they could be used to cure scurvy (due to their high vitamin C content).
"All Blue" is the most commonly marketed purple potato, and is increasingly available in supermarkets. Vines of this purple potato produce large, oblong potatoes with purple skin and flesh, with a light-colored layer just inside the skin.
