White sweet potatoes are native to South and Central America.
White sweet potato is a root vegetable used as an important source of starch in many parts of the world. Despite the fact that they are called potatoes, they are not closely related to true potatoes, but are in the same genus as morning glory. There are many varieties of sweet potato and also many varieties of white sweet potato. This name, white sweet potato, is used to describe the flesh and skin color of various sweet potato breeds.
Nutritionally, the lighter colored sweet potato such as the white sweet potato has more starch than its darker orange, red or purple color. They have less vitamin A and fewer carotenoids than brightly colored sweet potatoes and are often less sweet. Almost all sweet potatoes are classified as Ipomoea batatas, despite the many differences in the sweet potato varieties that are grown. Most other plants in this genus are toxic.
The tuber, or thickened root, is the part of the white sweet potato that is grown for use as a food source. Small shoots and buds are also edible, but are rarely eaten outside of the tropics and subtropics where these plants flourish. When dug up and removed from the rest of the plant, white sweet potato tubers stay at room temperature for several months, which makes them an important crop in the winter months when fewer vegetables can grow.
Although they were more popular, the white sweet potato lost popularity to the orange sweet potato in many parts of the world. Sweet potatoes with more carotenoids tend to be sweeter and softer, qualities that make them desirable for cooking. In many cases, these orange sweet potatoes are called yams, although they have nothing to do with real yams. Although the white sweet potato is less popular than the orange, it is still widely available almost all over the world.
White sweet potatoes are native to South and Central America. They are now grown all over the world, although they require soil temperatures between 70 and 80 degrees Fahrenheit (21.1 and 26.7 degrees Celsius) for them to thrive, making them best suited for tropical or subtropical climates. While these plants can be grown from seeds, they are most often grown from seedlings, which are pieces of the root of a mature plant.
