Abstract
‘NCORNSP-019SCSHLM’ is a moderately-compact to compact, non-twining, upright variety producing many short shoots. It is distinguishable from other cultivars by its yellow green heart shaped leaves that are entire with a cordate base; a compact habit and semi-erect mounding plant architecture. The lime green leaves of this plant, short internodes, and the plant architecture are what makes ‘NCORNSP-019SCSHLM’ unique amongst the current ornamental sweetpotatoes in the marketplace. ‘NCORNSP-019SCSHLM’ also exhibits very good vigor and is very well branched. In greenhouse and field trials, ‘NCORNSP-019SCSHLM’ has been shown to be much less vigorous than Ipomoea batatas ‘Margarita’ and ‘Blackie’ and is suitable for use as a landscape or containerized plant. The production of flowers by ‘NCORNSP-019SCSHLM’ is sporadic under short day conditions.
