You might be surprised to learn that there are FOUR types of blueberries. Highbush, lowbush, hybrid half-high, and rabbit eye. And within those types, there are hundreds of off-shoots. The most commonly planted blueberry is the highbush, and in the wild, you're more likely to find a strain called the northern lowbush. Wild lowbush is pretty resistant to disease and they have a longer growing season and more sweetness. They're just the quintessential blueberry. The big blue globes that you find in the supermarket are really far away from the wild ones.
