Summarize this article:

This variety grows well in USDA hardiness zones four through seven. Highbush is the most common type of blueberry and it yields large, dark berries on bushes six to eight feet tall. Set highbush blueberries 6 feet (1.8m) apart. This variety is best for eating fresh and for making desserts. This variety is resilient in cold weather and best for USDA plant hardiness zones two through six. This super-hardy variety grows low to the ground between 6 and 18 inches tall. Set lowbush blueberries 2 feet (0.6m) apart. Lowbush berries are small and sweet. They are good for baking muffins and pancakes. This variety does well in zones seven through nine and can tolerate heat and drought. The berries are typically smaller than highbush berries and they ripen a bit later in the summer than other varieties. Set rabbiteye blueberries 15 feet (4.6m) apart. If you do not have a lot of space to plant your blueberries, maybe opt for the lowbush or highbush variety instead of the rabbiteye variety. Blueberries have both male and female organs on the same flower, but not all are self-pollinating. If you want to be sure that your blueberries will be pollinated, plant different varieties within 100 feet (30.5m) of each other. Doing so allows bees to travel between plants and cross-pollinate.
Choose highbush blueberries for a warm climate. Select lowbush blueberries for cold weather. Go for rabbiteye bushes in a high heat climate. Prepare for healthy pollination.
