Jujube
枣 Ziziphus jujuba · Rhamnaceae
A small thorny tree with three fruit stages: crisp and green, brown and fresh, or wrinkled and dried.
Fresh, dried, and the stone
Jujube is eaten at different stages. Green fruit is crisp and apple-like; brown fruit is sweet and still fresh; wrinkled fruit is the dried form. PFAF describes the fruit as edible raw or cooked; the dried fruit is the one most often stored.
The stone is hard and should not be eaten. Dried fruit is sweet and chewy, which is pleasant but also means portion size matters for people managing blood sugar. PFAF advises caution in diabetics on medication (PFAF).
| Stage | What you see | Use |
|---|---|---|
| Green | Hard, green, apple-like | Fresh eating; not for drying |
| Brown | Fully coloured, crisp to soft | Fresh eating; best flavour |
| Wrinkled | Skin shrivels on the tree | Dry or store |
| Stone | Hard pit inside | Do not eat; keep from children |
Growing it
PFAF gives USDA zone 5–10 and describes jujube as a fast-growing deciduous tree of dry, stony slopes, with thorny branches and self-fertile flowers (PFAF). It needs full sun and a hot summer to ripen well; a warm, sheltered site gives the best chance in marginal climates.
Water young trees regularly for the first two years, then little. Prune in late winter to remove dead, crossing and low branches and keep the crown open. The tree can sucker; remove unwanted shoots promptly.
Harvest and drying
Pick the fruit when it is fully coloured and slightly soft, or leave it on the tree until it wrinkles for drying. Harvest in dry weather. The fruit ripens unevenly, so pick in stages.
Eat fresh, or dry the fruit whole in a dehydrator or a warm, airy place until leathery. Dried jujubes keep for months in an airtight container. The fruit is sweet and chewy; the stone is hard and should not be eaten.
- Pick fully coloured fruit in dry weather.
- Harvest in stages as it ripens.
- Dry whole until leathery, or eat fresh.
- Store airtight; remove the stone.
Identifying it
Jujube has glossy, ovate leaves with three prominent veins, small greenish-yellow flowers and reddish-brown fruit. The branches often zigzag and carry sharp thorns. The bark is rough and fissured on older trees.
Other Rhamnaceae and some ornamental shrubs have similar leaves. Do not eat fruit from an unidentified tree, and keep children away from the thorns.
Traditional context
Jujube fruit is a common food and traditional herb in China, used in soups, teas and sweet preparations. The dried fruit is also eaten as a snack across Asia.
For most people, culinary amounts are simply food. PFAF advises caution in diabetics on medication because of the fruit's sugar content. This page covers growing and handling, not a dose or treatment plan.

- PFAF advises caution in diabetics on allopathic medication; monitor and ask a clinician (PFAF).
- Concentrated extracts may interact with sedatives or blood-pressure medication; ask a pharmacist.
- Avoid medicinal doses in pregnancy without professional advice; food amounts are different.

Questions this plant raises
Can jujube grow in a cool climate?
It survives, but fruiting is unreliable without summer heat. Choose the warmest sheltered spot and an early-ripening cultivar.
Does jujube need a pollinator?
Most cultivars are self-fertile, but cross-pollination can improve fruit set. Plant two cultivars if you have room.
Why is my jujube dropping fruit?
Young trees often drop fruit, and dry soil or cool weather can cause more loss. Water consistently and wait for the tree to mature.
