Sweetheart Purple Sweet Potato Vine

Sweet Caroline Sweetheart Purple is a compact ornamental sweetpotato vine in the Sweet Caroline Series, valued for dense, dark-purple, heart- to spade-shaped foliage. The cultivar has good vigor, can grow with other species in containers, and produces pinkish morning-glory-like flowers sparingly, as described in its [plant patent](https://patents.google.com/patent/USPP18573P3/en) and the [RHS accepted-name listing](https://www.rhs.org.uk/plants/294977/ipomoea-batatas-sweet-caroline-sweetheart-purple-sweet-caroline-series/details). ## Growth and use The cultivar is compact to moderately compact and produces many shoots. In the patent’s 11-week trial, specimens measured 25 cm high and 44 cm wide; this age-specific observation is not a mature-size guarantee. [NC State Extension describes sweetpotato as a groundcover or vine and notes that ornamental cultivars are often used in mixed containers](https://plants.ces.ncsu.edu/plants/ipomoea-batatas/). ## Growing conditions Plant in full sun or partial shade in loamy, well-drained soil rich in organic matter. NC State reports species-level resistance to drought and dry soil and notes frost sensitivity; that broad guidance does not establish a hardiness-zone rating for this cultivar. ## Maintenance Use it in a container or allow room for its spreading growth in a bed. Trim runners if they extend beyond the intended space. The linked cultivar sources do not specify a watering interval, so none is prescribed here.
