Asian persimmons (Diospyros kaki) are the most commonly consumed type of persimmon, although there are many regional fruit types across the native distribution of the genus Diospyros. The 67 species of Diospyros are distributed in Africa, temperate Asia, tropical Asia, the Americas, and the Pacific Islands (Volk 2019). There were 3,800 acres of persimmons in production in the U.S. in 2017, with about 75% of the production in California (USDA NASS 2020).
Persimmons are usually consumed fresh, dried, or cooked. The most common non-astringent cultivar is ‘Fuyu’, which can be eaten fresh in either a firm or softened state. Astringent types of persimmons, such as ‘Hachiya’, are not consumed until they are very soft and have lost their astringency.
