'Elliott' blueberries are the latest to ripen, extending blueberry season into September. This variety needs to be fully ripe before being picked; otherwise, the fruits may be a bit too tart. Large berries are excellent eaten fresh or used in cooking. At least six hours of sun is a must for best tasting berries, and if you can plant another blueberry variety that blooms at about the same time, the berry production and flavor will be all the better for that. Blueberries are self-pollinating, but the cross pollination results in better yields.
