30-50 productive years.
25' high and at least as wide.
Inconspicuous, fragrant. Male flowers occur in groups of three, female flowers occur singly.
Usually male and female exist on separate trees but both can appear on the same tree, and rarely, perfect
bisexual flowers appear.
Many (female) cultivars will produce seedless fruit without pollination.
Some will need pollination. Pollinated flowers may produce seeded fruit that is larger and different
than unpollinated ones. A second cultivar nearby often increases the amount of fruit.
Years before fruiting:
Spherical to oval, with an indented stem and four sepals. The skin is thin, waxy, and
yellow to orange-red on the outside when ripe. The inside of the fruit is thick and pulpy, with a soft
to fibrous texture. Seeded varieties may have up to 8 seeds.
Persimmon cultivars fall into three groups: astringent, non-astringent and pollination-variant
(astringent when seedless). The immature fruit have a high tannin content with a very astringent taste.
As they mature, non-astringent cultivars like 'Fuyu' lose the tannins and become sweet when fully
colored and still hard. Astringent cultivars like 'Hachiya' do not lose the tannins when fully colored
and become edible only after they change to a very soft, custard-like consistency.
Months for fruit to ripen:
6-8. Harvest the fruit when fully colored but still hard, to avoid bird
predation. Use clippers to cut the stem just above the calyx (green leaf-like structure between the fruit
and the stem). The fruit tend to persist on a tree for several months after ripening. They will continue
to ripen after harvest, especially when placed in a bowl with apples or bananas.
Fruit that are not fully colored will take much longer to ripen off the tree.
Storage after harvest:
Several weeks at room temperature.
The quickest method to remove astringency from astringent cultivars like 'Hachiya' is to place the fruit
in a freezer for 24 hours. When thawed, the fruit are non-astringent. Otherwise, place them in a bowl and
leave them for several weeks until they are very soft.
Some cultivars, such as 'Fuyu' and 'Suruga', suffer chill damage in refrigeration, but can be frozen
or kept at 30-32°F, not above.
Other cultivars, such as 'Hachiya', can be refrigerated for up to one month, encased individually in
plastic bags. Do not expose to other ripening fruit in the refrigerator.
Persimmons can also be peeled and dried, whole or sliced, when hard. This will make even astringent
varieties sweet and ready to eat.
Medium to dark green, broadly lance-shaped, smooth margins, stiff.
The rootstock most commonly used for grafting is Diospyros lotus.
D. kaki itself has a deep tap root and some cultivars may not be grafted.
Cultivars of note:
'Chocolate' small to medium size fruit, sweet, spicy, firm brown flesh,
'Coffee Cake' / 'Nishimura Wase' medium size fruit, sweet, spicy, cinnamon-like
flavor, needs 'Chocolate' as pollenizer. The fruit will be astringent if not pollinated.
'Fuyu-Jiro' medium size fruit, sweet and mild flesh, keeps well, the tree is vigorous,
'Giant Fuyu' large fruit, sweet, flavorful.
'Hachiya' large fruit, sweet flesh, good for drying, the tree is vigorous,
The fruit attracts birds and mammals.
Toxic / Danger:
China. Cultivated for more than 2000 years.
