Sweet Caroline Sweetheart Mahogany Ornamental Sweet Potato Vine

Sweet Caroline Sweetheart Mahogany™ is an ornamental sweet-potato vine chosen for dark, mahogany-red, heart-shaped leaves. Proven Winners describes a mounded start that trails as the plant matures; the exact selection is designated NCORNSP-031SHMG. Its [plant profile](https://www.provenwinners.com/p/12310) and [patent record](https://patents.google.com/patent/USPP36237P2/en) document this specific cultivar and its container use. ## Form and color Published mature dimensions are 6–16 inches tall and 20–36 inches wide. The foliage retains saturated mahogany red in full sun, while the mounding habit develops into a trailing form that can spill over container edges. Proven Winners lists USDA zones 11a–11b and part sun to sun. ## Growing conditions NC State Extension describes *Ipomoea batatas* as adaptable to full sun or partial shade and well-drained, organically rich soil. Proven Winners rates this selection for average water; use a well-drained potting mix and check containers as they dry during warm weather. See the [NC State species guide](https://plants.ces.ncsu.edu/plants/ipomoea-batatas/). ## Maintenance Let shoots trail naturally or pinch them back when a tidier mound is preferred. Remove damaged growth and trim selectively if stems begin to crowd nearby plants.
