In fruit tastings at Dave Wilson Nursery, the Catalina plum scores exceptionally high. Tasters love the sweet, juicy flavor of this black plum that stays firm when fully ripe. The medium-sized fruit ripens from the last week of June to the 1st week of July. Although the spreading tree is partially self-fruitful, growers have noted better fruit set when planted with pollenizers such as Blackamber and Santa Rosa. Estimated chilling requirement 400 hours.
