Kerr crab apple tree

Malus domestica x Malus baccata 'Kerr'

Kerr crab-apples

Kerr is an interesting apple / crab-apple cross. The attractive crimson-pink fruits are small by apple standards, but relatively large for a crab-apple.

The fruits are extremely juicy, and have a good rich sweet-tart balance. They can be eaten fresh, but this is first and foremost an apple for juicing.
