Despite all the PR about the health benefits of the sweet potatoes, many of us never give this vegetable a second thought. We certainly don't grow it very often up north. I started growing sweet potatoes a few years back, mostly on a lark. It's true that sweet potatoes need a fairly long growing season and a good amount of space, but I've grown quite a few in a limited area, in USDA Zone 5/6. You could even grow them in a large container. Mine often take on some odd shapes, as you can see, but they still taste great. Even the greens are edible. And the best part of having your own supply of sweet potatoes is experimenting with them.
