When to Plant an Ornamental Potato

"Ornamental potato" is a common name for sweet potato vine or Ipomoea batatas. Sweet potatoes have long been a food crop, but some plants are bred specifically for decorative use. The tubers may be planted outdoors after the danger of frost has passed.

  1. Last Frost Date

    • The last frost date for a specific area is the latest date in spring when frost can be expected. Gardeners use the date as a point of reference for planting seeds, bulbs and tubers. County extension agents can provide this information, which is also available on the NOAA Satellite and Information Center's "Freeze/Frost Maps" website.

    Characteristics

    • Ornamental sweet potato vines have distinctive palmate foliage in shades of chartreuse or purple. Some cultivars have variegated leaves. The vines can reach 8 to 10 feet in length and are best used as a ground cover or a "spiller," trailing out of containers.

    Storage

    • Though ornamental sweet potato is usually treated as an annual, it is actually a tender perennial. In cold winter climates, the tubers can be lifted and stored after the first frost. Store them in a vermiculite-filled paper bag in a cool, dry place. Divide them if necessary and replant them in spring.
