Its patent description notes short shoots, dense branching, yellow-green cordate leaves and a semi-erect mound; the breeder lists a trailing habit, with stems trailing up to 20 inches. Flowers may appear sporadically and range from cream to light lavender, so this selection is valued mainly for foliage.

For species-level guidance, [NC State Extension](https://plants.ces.ncsu.edu/plants/ipomoea-batatas/) recommends loamy, well-drained soil with organic matter; its broader species-size figures do not replace this selection’s listed mature dimensions. Proven Winners rates its water needs average and notes heat tolerance. The species is frost-sensitive and this cultivar is generally grown as an annual, though its patent notes it can persist in mild-winter locations. ## Maintenance Use it as a spiller in baskets and containers, or in borders, mass plantings and seasonal groundcover. Allow room in mixed planters: Proven Winners notes that its vigorous trailing growth can overtake less vigorous companions. The breeder rates maintenance easy and says deadheading is unnecessary.
