What does wild mean, and how does that differ from the ordinary blueberries you’d find in the fresh produce section at the supermarket? The wild blueberry’s heritage goes back 10,000 years. These berries aren’t planted; rather, they grow in the wild. While smaller than ordinary blueberries, wild blueberries give you more than twice the number of berries per cup compared with cultivated blueberries and 25% more cups per pound.
