Purple Sweet Potato Origins
Purple sweet potatoes have been around for centuries and have a rich history. The Okinawan sweet potato is believed to have originated in the Americas and was brought to Japan in the early 1600s. It was then introduced to Hawaii in the early 1900s, where it became a popular staple food.
The Stokes Purple® sweet potato, on the other hand, hails from North Carolina. It was first discovered by a sweet potato farmer named Mike Sizemore, who received some purple-colored potatoes as a gift from an unidentified woman. He liked them so much that he began to cultivate them, eventually obtaining a patent and launching them in the commercial market.
Purple sweet potatoes are a member of the Ipomoea genus, just like other sweet potatoes. There are two main varieties of purple sweet potatoes: the Okinawa (white skin) and Stokes (purple skin). Both varieties have a deep purple flesh, which is what gives them their unique color.
In addition to their vibrant color, purple sweet potatoes are also known for their nutritional benefits. They are high in antioxidants, which can help protect the body against damage from free radicals. They are also a good source of fiber, vitamins, and minerals.

Purple sweet potatoes can be found in most grocery stores, usually in the produce section. When selecting sweet potatoes, it is important to choose ones that are uniform in size so that they cook evenly.
Storage and Shelf Life
To extend the shelf life of purple sweet potatoes, it is important to store them properly. The potatoes should be stored in a cool, dry place, such as a pantry or a kitchen cabinet. The ideal temperature for storing sweet potatoes is between 55-60°F. If stored properly, raw sweet potatoes can last for up to a month.
It is important to note that purple sweet potatoes have a shorter storage lifespan than regular potatoes, so it is best to use them within a week or two of purchase. To ensure that they stay fresh, do not wash the potatoes before storing them, as excess moisture can cause them to spoil more quickly. Instead, store them in a breathable container, such as a basket or a paper bag.
