This is a very cold hardy strain of crabapple. Crossed between Dolgo x Haralson Red, Kerr has gained a reputation as "one of the Crabapple trees to have" for Whitetail habitat. What makes this crab desirable is it’s large fruit size just under 2” and the late ripening of the fruit, combine this with easy to grow and care for, you can see why it's popular..
