One of the easiest ways to create multi-seasonal interest in the garden is to use plants with interesting foliage. Sweet potato vine, named for its edible cousin, is an ornamental warm-season annual grown for its attractive leaves and vining habit. The vigorous vines can reach up to 10 feet long and are most often used as spillers in combination containers. They can also be used as a ground cover or grown up a trellis. Versatile and gorgeous, you can pick from a range of vivid colors!
