Description & Overview

Black Ice plum produces large round black fruits that ripen in early August in Wisconsin. The fruit is sweet, juicy and semi-cling. This plum was derived from a complex cross of Western Sand Cherry (Prunus besseyi) with Japanese plum genetics. The goal by the breeder was to obtain a Japanese type plum that was hardy enough to grow in the upper mid-west yet had the quality to compete with Japanese plums readily available on the summer markets from west coast growers.
