"Selected by R. Neal Peterson as a seedling of Overleese. Large fruit with few seeds (approx 7% by weight). Flavor is refreshing and refined, agreeably mild and moderately sweet, with a pleasant, long-lingering aftertaste. Texture resembles a firm custard, firmer than wild pawpaws. Ripens in September in Kentucky. Patented 2004; propagation restrictions apply."
