About the Castleton :
The Castleton prune fruit is of medium size that
rarely split. It is one of the best eating prune
available. This prune tree is very productive and is
relatively small. The prunes are early and are a
high quality blue plum, ripening a month before
Empress.
Dual purpose -- a fine early dessert plum, but
also an excellent processing variety. Castleton
prunes are freestone; pit does not shatter or split.
