Its unusual climbing habit can be directed up a trellis, while the stems also trail from containers and baskets. The [Proven Winners profile](https://www.provenwinners.com/plants/ipomoea/sweet-caroline-upside-key-lime-ornamental-sweet-potato-vine-ipomoea-batatas) lists a mature height of 3–6 feet and spread of 18–36 inches, notes that the foliage color is deeper and brighter in full sun than in shade, and identifies the selection as NCORNSP-028SCKL. ## Landscape Uses Use this annual vine on a trellis, in hanging baskets, or in containers; the breeder also lists landscape, groundcover, mass-planting, and focal-point uses. The [NC State Extension sweet potato vine guide](https://plants.ces.ncsu.edu/plants/ipomoea-batatas/) gives broader species advice: plant in full sun or partial shade in loamy, well-drained soil enriched with organic matter, and protect the frost-sensitive vine from cold. ## Growing Sweet Caroline Upside Key Lime is rated average for water. It performs well in heat and humidity; cooler conditions and low humidity keep it more compact. In garden beds, add compost or fertilizer; feed container plants regularly. In mixed planters, cut back or redirect stems if they begin to crowd companion plants. ## Maintenance Trim or guide the stems as needed to keep the vine on its support or within its container. Deadheading is not necessary.
