Ipomoea batatas 'Sweet Caroline Sweetheart Purple'
Sweet Caroline Sweetheart Purple sweet potato vine
Deep burgundy-purple, heart-shaped leaves bring lasting contrast to summer containers. Its spreading stems fill gaps and spill over pot edges, pairing especially well with lime foliage or pale flowers. This is the original Sweetheart Purple selection, not its later Jet Black replacement.
