Ziziphus

These deciduous and evergreen trees and shrubs are natives of the warmer climates. Some are found in California, Texas and Mexico. The most popular is Z. jujuba, commonly known as the Jujube or Chinese Date. The Chinese Date isn't a true date tree, but the 1- to 2-inch, edible fruits resemble dates and can be eaten fresh, dried or preserved. This tree ultimately grows from 15 to 25 feet high and provides a light, filtered shade. Its spiny branches are clothed with �- to 2�-inch, dark green leaves that are quite pest-resistant. In early summer, the Chinese Date produces clusters of tiny, yellow flowers, followed by the fruits, which ripen in late fall. This tree ordinarily begins to produce fruit the first year it is planted. The wood of this tree is hard and heavy and is widely used in some countries.

Pot Cultivation

The Chinese Date should be grown in milder climates; it does better where the summers are long and hot. It can be grown in full sun or light shade in almost any soil, though the better the soil the more valuable the fruits will be.

Propagation

These trees are increased by rooting cuttings or by grafting named varieties on understocks raised from seeds.
