Discussion
The fruits of Ziziphus jujuba have a datelike taste and are eaten fresh, dried, candied, or preserved. Hundreds of cultivars have been developed in China. The spineless var. inermis (Bunge) Rehder sometimes is identified as a cultivar.
The species was first introduced to North America in 1837 and has spread widely. It is not always clear whether it is naturalized or persisting from earlier plantings.
The name Ziziphus zizyphus (Linnaeus) H. Karsten, sometimes used for this species, is a tautonym and therefore illegitimate.
Selected References
None.
