Things You'll Need
Jar or mug
Sweet potatoes, are actually related to morning glories and can sprout a quick growing vine that will trail beautifully where you train it. Grow a sweet potato vine in a container on your porch or patio, or plant one in a pot right in your house.
Choose a firm sweet potato from the produce section of your grocery store or the local farmer's market. If you find one that has started sprouting, even better.
Poke four toothpicks into the sweet potato in a cross shape (one on each side) a little over halfway up the sweet potato.
Fill a mug or jar with water and place the sweet potato in. The toothpicks should suspend the top half of the sweet potato, keeping that half dry.
Place in a sunny spot and change the water as needed. After several weeks, the vines and leaves will begin to grow.
Plant your sprouting sweet potato in a pot with soil or in your garden after six to eight weeks. The leaves are beautiful and your plant might even grow some sweet potatoes for you to eat.
Plant sprouted sweet potatoes in May and you can dig up yummy tubers in the fall.
