Chestnut Crab apple is frequently used as a pollinator for other apples. It is also one of the few cultivars that is self pollinating, although another cultivar nearby is advisable. Introduced by the University of Minnesota in 1946 and released in 1949 , the 15 to 20 foot trees produce a yellow crab apple with red highlights, some say a red crab apple with yellow blushes. The crisp flesh is sweet with an earthy nut like flavor. Most crab apples are typically cherry sized, these are larger, averaging 2 inches round.
Chestnut Crabapple is not fully resistant to any common blights it has a good general disease resistance, but is somewhat susceptible to cedar apple rust.
