20 Types of Sweet Potatoes to add to Your Garden

Sweet potato fries may have started to gain popularity a few years ago, but sweet potatoes have been a staple in many people’s diets for decades. You can get types of sweet potatoes that range from orange to cream-colored to purple and red, and they have a history stretching back over 5,000 years. They’re now grown throughout the world, and there are over 7,000 varieties.

Most people grow sweet potatoes as a food source, and you can find varieties to fit a range of different growing conditions and areas. They all have different temperature and light requirements, and many have various tastes. There are also sweet potatoes available that get grown for the pretty vines. The ornamentals may not kill you if you eat them, but they don’t have the most pleasant taste.

Unlike most plants you have in your garden, you don’t start sweet potatoes from seeds. Instead, you start sprouts called slips from last year’s roots that you wintered. You cut these slips off the sweet potato vine and put them in water to allow the roots to grow. Once enough roots grow, you bury the root end into the soil until you reach the first set of leaves. Then, you wait between three and four months for the sweet potatoes to sprout and grow.

Marketing campaigns in the mid 1900s made many people confused sweet potatoes for yams. These campaigns tried to market the orange colored sweet potato while separating it from the yellow or white varieties. Also, sweet potatoes are from a totally different family than the traditional potato. Sweet potatoes belong to the morning glory family while potatoes come from the nightshade family with tomatoes. This is why there are huge nutritional differences between the two, and the sweet potato comes out ahead when it comes to nutrition.
