Castleton™ comes out of the Cornell University research program. Since it's release in 1993, it has become known as the sweetest of the early ripening Europeans. This mid-size, high-quality, deep blue plum will colour up well before maturity, so your best bet is to check them by biting into one to determine when to pick. Castleton™ is considered a dual-purpose variety – a fine early dessert plum, but also excellent for processing or drying. The tree is a somewhat slow grower, with a spreading pattern, but is a consistent heavy producer.
