3-in-1 Blueberry Bush (Southern Highbush)3 types of blueberries on one bush! Enjoy fresh blueberries for months! These shrubs are the result of three different blueberry varieties grafted onto a single rootstock to give you a single bush that produces berries from spring into fall. You'll have berries to pick all summer, instead of all at once. You'll save space and turn any small area of your yard into a mini blueberry factory. This compact 4 foot bush will give you buckets of berries!
