Summary
Source: WikipediaCeltis jessoensis, known as the Japanese hackberry or Jesso hackberry (from an archaic reading of "Ezo": Hokkaidō), is a species of hackberry native to Japan and Korea. It is a deciduous tree growing to 20–25 m (66–82 ft) tall. The leaves are 5–9 cm (2.0–3.5 in) long and 3–4 cm (1.2–1.6 in) broad, with a sharply serrated margin, glaucous beneath and downy on the leaf veins.
Description
Deciduous tree reaching 15 m tall, hardy to UK zone 6. Flowers in April with seed maturity in October. Hermaphrodite flowers pollinated by bees. Prefers light sandy to medium loamy, well-drained soils and tolerates poor fertility. Suitable for mildly acidic to basic soils. Demands full sun, cannot grow in shade. Accommodates dry or moist soil and withstands drought well.
Edible Uses
The fruit can be eaten raw. It likely consists of a thin, sweet but dry and mealy flesh surrounding a single large seed.
Traditional Uses
The ripe fruit are eaten.

Where It Grows
Asia, China, Japan, Korea,
Cultivation
Succeeds in any reasonably good soil, preferring a good fertile well-drained loamy soil. Succeeds on dry gravels and on sandy soils. Established plants are very drought resistant. Trees prefer hotter summers and more sunlight than are normally experienced in Britain, they often do not fully ripen their wood when growing in this country and they are then very subject to die-back in winter. Trees can be very long-lived, perhaps to 1000 years. This species is closely related to C. bungeana. Plants in this genus are notably resistant to honey fungus.
Propagation
Seed is best sown as soon as it is ripe in a cold frame. Stored seed should be given 2–3 months of cold stratification before sowing in February or March in a greenhouse. Germination rates are usually good, though stored seed may take 12 months or more to germinate. Seed can be stored for up to 5 years. Prick seedlings out into individual pots as soon as they are large enough to handle. Seedling leaves often show white patches lacking chlorophyll — this is normal, and older plants produce fully green leaves. Grow seedlings on in a cold frame through their first winter, then plant out the following late spring or early summer, with some cold protection during their first winter outdoors. Cuttings can also be used.
Other Uses
None known.
Notes
There are 70-100 Celtis species. They are mostly in the tropics. There are 8-10 species in tropical America. Also put in the family Ulmaceae.
