Vaccinium 'O'Neal' stands out among Southern Highbush blueberries for its exceptional flavour profile and generous yields of large, dark blue berries that ripen remarkably early and continue producing throughout an extended harvest window. This self-fertile cultivar requires minimal winter chilling—just 400 hours—making it well-suited to milder growing regions. The plant displays distinctive gray-green foliage that persists as evergreen in temperate climates, while transitioning to striking crimson tones before dormancy in colder zones. An excellent choice for growers seeking superior fruit quality with reduced chill requirements.
