In which plant genus does the Sweet Potato Vine fall?

The Sweet Potato Vine is classified under the genus Ipomoea. This genus is part of the morning glory family (Convolvulaceae) and includes various species known for their ornamental and edible qualities. Ipomoea batatas, specifically, is the species name for the sweet potato, which is cultivated for its edible tubers and often grown as an ornamental vine for its attractive foliage and vibrant color variations.

The other genera listed in the options represent different types of plants. For example, Catharanthus includes annual flowering plants such as Vinca, which are often used in landscape design; Pelargonium encompasses geraniums and is known for its flowering varieties; Tagetes consists of marigolds, popular for their bright blooms and pest-repelling properties in gardens. Each of these genera serves different horticultural purposes and does not include the sweet potato vine, making Ipomoea the only correct choice in this context.
