Polka is a Ballerina apple variety raised at East Malling Research Station, Kent UK in 1976 from a Wijcik McIntosh x Golden Delicious. Medium sized, round conical
fruit. Smooth dark red flushed skin. Crisp and juicy with a flavour similar to Spartan.
Ballerina trees naturally grow in a columnar form. Side branches are not normally produced and the
fruit is borne on the main trunk. They are very slow growing and will usually be much smaller in
size when supplied than to other apple trees. Because of their slow growth rate and naturally
dwarfing habit they are usually grafted on fairly vigorous rootstocks such as MM106 and MM111. They
will grow up to 8ft (2.4m) in height. They require no pruning other than the removal of side
branches when they occasionally form.
