Harco ISK trees are medium to vigorous in growth with a spreading or semi-open crown. Fruits have an average weight of 140–160 g, a rounded shape, and smooth skin of a greenish-yellow color with an intense red-purple blush. The flesh is yellow, juicy, with good stone separation.
The variety possesses high resistance to diseases and is one of the most winter-hardy among nectarines due to its relatively late flowering. The plant is self-fertile and does not require pollinator varieties. Due to a tendency for overcropping, the variety requires fruit thinning to obtain a high-quality yield.
