Sweet potatoes are actually only distant relatives to potatoes. As a plant, they go by the name of dicotyledonous, and they belong to the family of Convolvulaceae. Throughout many parts of North America, sweet potatoes that are of the orange and softer variety are simply known as yams. This is to differentiate that variety from the other kind, which is a more firm, white one. Since yams are actually a distinct vegetable apart from sweet potatoes, the US Department of Agriculture actually mandates that sweet potatoes that are tagged as yams also be identified as actual sweet potatoes. While sweet potato leaves and shoots are good for eating, too, their tuberous and starchy roots are by far the most popular part of the vegetable.
