Saijo Persimmon: The Sweet, Cold-Tolerant Astringent Persimmon

By the Garden Voila editorial team · Updated October 30, 2026 · How we verify

The Saijo persimmon is an old Japanese astringent persimmon (Diospyros kaki) prized as one of the sweetest of all persimmons. Its small, elongated, egg-shaped, yellow-orange fruit must be eaten completely soft, when the flesh becomes translucent, jelly-like and honey-sweet, and it is a favorite variety for making hoshigaki, Japanese dried persimmons. The tree is partly self-fertile and sets seedless fruit without a pollinator, grows about 15 to 25 feet tall, ripens in late September to October and is considered one of the more cold-tolerant Asian persimmons, usually grown in zones 7 to 10.

Saijo persimmon overview

What is a Saijo persimmon?

Saijo is a traditional Japanese variety whose name is often translated as “the very best one.” It has been grown in Japan for centuries, particularly for drying. The University of Florida IFAS persimmon guide lists Saijo among the astringent cultivars and describes it as one of the sweetest, with translucent, jelly-type flesh. Like Hachiya, it is astringent until soft, so firm fruit is inedible. When fully ripe, though, many growers rate it above every other persimmon for sweetness.

Saijo is one of several astringent Asian persimmons. For how it compares with non-astringent types such as Fuyu, see our guide to persimmon varieties.

What does a Saijo persimmon taste like?

A fully ripe Saijo is intensely sweet, with a honeyed, apricot-like flavor and a smooth, translucent, jelly-soft texture. The Nature Hills Nursery variety description calls the flavor honey-like, intensely sweet and juicy, with few to no seeds. Eaten firm, it is unpleasantly astringent, like any astringent persimmon, so patience is essential.

What does a Saijo persimmon look like?

• Fruit shape: Small to medium and elongated, egg-shaped or slightly pointed, narrower than a Hachiya.
• Color: Yellow-orange when mature, deepening to translucent orange when soft.
• Calyx: A green, four-lobed cap at the stem end.
• Tree: An upright, rounded tree with large, glossy, oval leaves that turn orange and red in fall.

How cold hardy is the Saijo persimmon?

Saijo is often recommended as one of the more cold-tolerant Asian persimmons, which makes it popular with growers at the colder edge of persimmon country. Nurseries usually list it for zones 7 to 10, and some gardeners grow it successfully in sheltered spots in zone 6. Young trees are more vulnerable than established ones, and new spring growth can be damaged by late frosts. Plant on high ground away from frost pockets, and protect young trees during severe cold. Check your zone with the growing zone finder. Where winters are too cold for any Asian persimmon, consider the native American persimmon or a hybrid.

Does a Saijo persimmon need a pollinator?

No. Saijo is parthenocarpic, meaning it sets seedless fruit without pollination, and Nature Hills describes it as partially self-fertile. A single tree will fruit. Another Asian persimmon nearby may improve fruit set and reduce fruit drop, but it is not required. Because Saijo is a pollination-constant astringent type, pollination does not change its flavor or flesh color, unlike Chocolate.

How do you plant a Saijo persimmon?

1. Choose a sunny site with at least 6 to 8 hours of sun and well-drained soil.
2. Start young. Persimmons have a long taproot, so young container or bare-root trees establish best.
3. Plant in late winter or early spring. Dig a hole as deep as the root system and twice as wide; the planting hole size calculator gives the dimensions.
4. Water deeply after planting and weekly through the first summer.
5. Mulch 2 to 4 inches deep in a wide ring, away from the trunk.
6. Space trees about 15 to 20 feet apart.

How do you care for a Saijo persimmon tree?

Watering

Keep soil evenly moist during the first two years and during summer droughts after that. Drought stress is a common cause of fruit drop in persimmons.

Fertilizing

Persimmons need modest feeding. Excess nitrogen leads to leafy growth and fruit drop. Apply a light, balanced fertilizer in early spring only if growth is weak. See our fruit tree fertilizer guide.

Pruning

Train a young tree to a central leader or open center with well-spaced scaffold branches. Once established, prune lightly in late winter to remove dead wood and thin crowded shoots. Persimmons fruit on new shoots that grow from the previous year’s wood, so avoid heavy cutting, which removes fruiting wood. Keeping the tree lower makes harvesting soft fruit much easier.

Thinning

Saijo can bear heavily. Thinning crowded fruit in early summer reduces limb breakage and alternate bearing and gives better-sized fruit.

When is a Saijo persimmon ready to pick?

Saijo ripens from late September into October in most areas. Pick fruit when it is fully colored yellow-orange, either while still firm or once it begins to soften. Clip the stem with pruners, leaving the calyx attached. Fruit picked firm will soften indoors over one to three weeks at room temperature. It is ready to eat when it feels like a water balloon and the skin looks translucent. Birds love ripe persimmons, so picking firm and ripening indoors is often the safest approach.

How do you eat a Saijo persimmon?

Wait until it is completely soft, then cut off the top and scoop out the sweet jelly with a spoon. Chill it first for a refreshing dessert. Soft pulp can also be blended into smoothies, stirred into yogurt or baked into breads, cookies and puddings. Freezing a soft Saijo and eating it partly thawed gives a natural sorbet.

How do you make hoshigaki from Saijo persimmons?

Hoshigaki are Japanese hand-massaged dried persimmons, and astringent varieties such as Saijo and Hachiya are the traditional choice because drying removes all astringency. The basic method:

1. Pick firm, fully colored persimmons with a T-shaped piece of stem left on.
2. Peel the fruit, leaving the calyx and stem.
3. Tie string to the stems and hang the fruit in a dry, airy place out of the rain, ideally with good sun and cool nights.
4. After about a week, when a skin has formed, gently massage each fruit every few days to break up the pulp and draw sugar to the surface.
5. Continue for about 3 to 6 weeks until the fruit is firm, chewy and dusted with a white sugar bloom.

UF/IFAS notes that sun-drying or drying in a food dryer removes all astringency. Hoshigaki are a slow but rewarding project and keep for months in a cool place or the freezer.

How do you remove astringency from Saijo persimmons quickly?

If you do not want to wait for fruit to soften on the counter, UF/IFAS lists several methods: freezing the fruit for 24 hours, covering it with uncooked dry rice for 3 to 5 days or exposing it to ethylene gas, for example by sealing it in a bag with ripe apples or bananas. Frozen and thawed Saijo turns soft and sweet without the long wait.

How do you store Saijo persimmons?

Firm, mature Saijo persimmons keep for a few weeks in a cool room or the refrigerator while they slowly ripen. Once soft, refrigerate and eat them within a few days. For long storage, freeze soft pulp in containers or freeze whole fruit, or dry them into hoshigaki. Handle soft fruit very gently; it bruises and splits easily.

Why are persimmons so important in Japan?

Persimmons, called kaki in Japanese, have been cultivated in Japan for more than a thousand years and are a symbol of autumn. Many rural homes grow a tree by the house, and strings of peeling persimmons hanging under the eaves to dry are a classic fall scene. Dried persimmons, known as hoshigaki, were historically an important winter food and remain a prized New Year delicacy. Saijo is one of the traditional varieties used for drying, which is part of why it has survived for centuries despite its small size.

Can you grow a Saijo persimmon in a container?

Yes, for a number of years. Choose a deep container of at least 15 to 20 gallons to accommodate the taproot, a well-drained potting mix and a sunny spot. Water whenever the top couple of inches of mix are dry and feed lightly in spring. Container trees stay smaller and fruit less, but in borderline climates you can move them into an unheated garage or against a warm wall during severe cold. The container garden planner helps you size the pot.

Saijo persimmon care calendar

Are Saijo persimmons healthy?

Persimmons are a good source of fiber, vitamin A (from beta-carotene), vitamin C and manganese, and they provide antioxidant compounds. Nutrient values for persimmons are listed in the USDA’s FoodData Central database. Very sweet varieties such as Saijo are also high in natural sugar, especially when dried into hoshigaki.

How long does a Saijo persimmon tree take to fruit?

Grafted Saijo trees usually begin bearing about 3 to 5 years after planting, with crops increasing steadily as the tree matures. Young trees often drop much of their fruit in the first years; this is normal and usually improves as the tree establishes. Avoiding heavy nitrogen feeding and keeping soil evenly moist through summer both help the tree hold its crop. Once mature, a healthy Saijo can bear heavily for decades.

Because Saijo fruit is so soft when ripe, many growers pick it firm and ripen it indoors, or freeze it whole and eat it like sorbet. See Hachiya vs Fuyu for how astringent and non-astringent types compare.

Saijo traits and persimmon basics from University of Florida

University of Florida IFAS Extension considers Saijo one of the sweetest persimmons, though slight astringency may remain when the fruit is soft. The fruit is relatively small and long-conic, with translucent orange jelly-type flesh and a relatively thin peel, and soluble solids of 16 to 22 percent. It ripens early to mid-season on a large, upright, vigorous tree that yields heavily and suits home growers.

Astringent or not

Astringent persimmons must be soft or artificially treated before eating because tannins cause the puckering taste. Non-astringent types lose astringency while still firm and can be eaten hard or soft, and they keep better. Persimmons are also classed as pollination-variant, with dark streaks around the seeds, or pollination-constant. Florida growers usually grow pollination-variant astringent types without pollinators, and Gailey is the standard pollinator for those that need one.

Harvest windows and cold

For comparison, UF lists non-astringent Izu from late September to mid-November, Jiro from mid-October, Fuyu from mid-November to early December and Suruga from late November. Among astringent types, Nishumura Wase ripens first in early August and Tanenashi runs September through November. Persimmons fruit best in central and northern Florida; early-starting cultivars such as Giombo and Ormond risk freeze injury. The document does not discuss chilling requirements, so check your local extension for hardiness in colder regions.
