Abstract

A new and distinct cultivar of plum, similar to a Japanese-American hybrid-type originating as a hybrid seedling of the cross: ‘Oka’×‘Z's Blue Giant’. The present cultivar is unique from its maternal parent and other plums adapted to the Midwest Zone 3b and above, because it is similar to many California dessert plums (dark blue-black and nearly round) and with a superior ripe flavor to most common cultivars tested in its ripening season. The instant cultivar is also more dwarf in growth habit and has an earlier fruit maturity than most common midwest plums.
