How to Grow a Decorative Potato Vine

Ornamental sweet potato vines are very disappointing when planted as an edible crop. The white-fleshed tuber doesn't compare in flavor to its orange-fleshed relative. They are both scientifically known as Ipomoea batata and in the morning glory family, but ornamental types are bred specifically for their colorful leaves in pink, green, white, chartreuse, reddish purple and purple-black. Some common varieties are Margarita, Tricolor or Pink Frost. The vines are fast-growing, making them suitable for trailing down planters, pots and hanging baskets or used as ground cover.

Instructions

  1. Growing from Leaf Cuttings

    • 1

      Cut off a section of vine from an existing plant right under the leaf node, or where a leaf grows out of the vine, at a 45-degree angle.

    • 2

      Remove the lower leaves and place the stem in a glass or jar of water. Do not submerge any leaves in the water. Place in an area that gets indirect sunlight.

    • 3

      Change water every day or so to keep the glass or jar full.

    • 4

      Plant leaf cutting in potting soil in a pot once roots become a few inches long and full.

    Growing from Tubers

    • 5

      Dig a hole in potting soil or light cultivated ground soil wide enough to accommodate the tuber and deep enough to completely cover it.

    • 6

      Place tuber on its side, fill with soil and firm into the ground.

    • 7

      Space plants 9 to 18 inches apart when using as a ground cover.

    • 8

      Keep soil evenly moist, as vines wilt when dry. They recover nicely when watered.

    • 9

      Dig up tubers in fall and let them set to dry for a few days. Do not wash them off but brush off any dirt. Store in a plastic container with a lid filled with straw or peat moss over winter and plant again when weather warms up. Bring vines in pots indoors before cold weather arrives, as frost kills them.
