Highbush blueberries reach up to 12 feet in height, according to University of Illinois Extension. Examples of common highbush varieties include bluecrop and jersey. Bluecrop, the most commonly planted blueberry bush, grows to a height of 7 feet.
Lowbush varieties, sometimes known as wild blueberries, grow approximately 1 to 2 feet high. They grow wild throughout the eastern United States, producing small, sweet fruit.
Half-high or rabbit eye varieties, such as Northland, reach 2 to 5 feet in height. Disadvantages of these cultivars include early blooming and extensive pruning requirements, according to Michigan State University Extension.
