Preston Prolific is thought to be a seedling of Black Genoa and originated in Victoria. The tree is vigorous with large leaves. The fruits are borne on a short stalk and green when immature, changing from straw to purplish brown when fully ripe. The flesh is very thick, creamy white and juicy with a distinctive sweet flavour. The pulp is amber coloured, sometimes tinted red. Fruit splitting is not a problem. The fruit matures in December to late April.
