Sweet potato is not closely related to potato. Sometimes known by the common name yam, sweet potato should not be confused with Dioscorea which are also known as yams but belong to a different plant family. There are two types of sweet potato plants – vines or bushes. The leaves are up to 10 cm long, heart shaped with toothed margins. Flowers have petals that are lavender to pale purple or white, forming a trumpet shape up to 7 cm long, often darker in colour inside the tube. The sweet potato is the tuberous root of the plant. ‘Sweet Caroline Bronze’ has bronze to purple-bronze leaves with purple veins. This variety is great for planting in a container combination for your patio or as a feature plant.
