By using a few simple techniques, you can easily grow it into a beautiful houseplant that will brighten your home during the long winter months. You can let the plant continue to grow in the water or transfer it to a pot, and during summer, it can be planted outside where it makes a wonderful ornamental plant.

You can grow a vine from a sweet potato.

Starting Your Sweet Potato Vine

Step 1

Choose a fresh, firm sweet potato that has budded. You can use any color sweet potato. If you are going to grow more than one plant, try planting different colors.

Step 2

Hold the potato so it is vertical and place four to six toothpicks in a circle around the potato, about halfway down.

Step 3

Put the potato in the vase with the narrower end pointing down into the jar. The toothpicks should hold the potato suspended with a bit of the potato sticking out of the vase.

Step 4

Fill the vase with water and place it in a warm, sunny location in your house. The plant should begin to grow in about three days.

Step 5

Change the water every week to keep the plant healthy and discourage pests.

Potting Your Sweet Potato Vine

Step 6

Put a few rocks into the bottom of a medium-size clay pot and fill it halfway up with potting soil.

Step 7

Carefully remove the sweet potato from the jar and transfer it into the pot with the roots down.

Step 8

Continue to add more soil to the pot until the potato is covered in soil up to the vines.

Step 9

Put it back in its original place for a week or two. You can leave it there or move it to a new warm, sunny place once it acclimates.

The sweet potato is a relative of the morning glory.

Step 10

Transfer your plant to a warm sunny spot in the garden after the danger of frost is past.
