6 Amazing Types of Sweet Potatoes with Growing Tips and Tried Recipes

Introduction :

Sweet potatoes are more than just a holiday favorite. Their vibrant colors, nutritional power, and culinary flexibility make them a staple in kitchens around the world. From the deep orange Beauregard to the creamy white Japanese Satsumaimo, each variety brings something different to the table.

Understanding the different types of sweet potatoes helps gardeners, cooks, and health-conscious individuals choose the best ones for their needs. In this guide, we’ll explore sweet potato types, compare white sweet potato vs orange sweet potato, and help you understand the difference between sweet potatoes and yams.

🌿 What Is a Sweet Potato ?

Despite their name, sweet potatoes are not actually related to regular potatoes. Sweet potatoes belong to the morning glory family (Convolvulaceae), while common potatoes come from the nightshade family. Sweet potatoes are tuberous roots, not stem tubers like white potatoes.

The plant, scientifically known as Ipomoea batatas, grows best in warm climates. Native to Central and South America, it has been cultivated for thousands of years.

These roots are known for their naturally sweet taste, which intensifies when cooked. They come in various shapes, colors, and textures making them one of the most versatile crops you can grow or cook with.

🍯 How Do They Become Sweet ?

Sweet potatoes get sweeter when cooked, thanks to natural enzymes that break down starches into sugar. The key enzyme, amylase, becomes more active at certain temperatures, especially during baking or slow roasting.

As sweet potatoes cook, especially at temperatures around 170–190°F (77–88°C), their starches convert into maltose, giving them their signature sweetness. This process explains why roasted sweet potatoes often taste much sweeter than steamed or boiled ones.

Varieties differ in sweetness too. Japanese and purple types are usually milder and drier, while orange varieties like Garnet and Beauregard are moist and sugary.

🍠 What’s the Difference Between Sweet Potatoes and Yams ?

It’s a common mix-up, but sweet potatoes and yams are not the same. In fact, most “yams” sold in U.S. supermarkets are actually sweet potatoes.

• Yams are starchy tubers native to Africa and Asia, belonging to the Dioscorea family. They have rough, bark-like skin and are typically white or purple inside, with a dry texture.
• Sweet potatoes are smoother-skinned, with orange, white, or purple flesh. They’re sweeter, moister, and more commonly used in Western recipes.

The USDA allowed the term “yam” to describe orange-fleshed sweet potatoes decades ago, mainly for marketing. So if you’re buying “yams” in the store, you’re probably just getting a different sweet potato type.

Avoid those with cracks, sprouts, or mold. Store them in a cool, dry, and dark place—not in the fridge, which can change their texture and taste.

Curing sweet potatoes (allowing them to rest in a warm, humid area for 7–10 days after harvest) helps convert starches into sugars and improves flavor.

Stored correctly, they can last 2–3 months.

💪 Health Benefits :

Sweet potatoes are a nutritional powerhouse:

• High in vitamin A (from beta-carotene)
• Rich in vitamin C, B6, and potassium
• Good source of fiber, especially with skin on

Their antioxidants help reduce inflammation and promote gut health. Purple varieties contain anthocyanins, which support brain and heart function.

White sweet potatoes are great for those monitoring blood sugar. They offer a lower sweetness level while still being nutritious.
