Fruiting Branches of the Chinese Jujube (Ziziphus jujuba) in California, S. P. I. 



No. 30488. 



The Chinese jujube grows rapidly and fruits early and heavily in the interior valleys of northern 

 California, where the temperatures rise to 120° F. in midsummer. Unlike most other fruit trees, 

 the twigs which bear the fruits are produced as leafy shoots (resembling compound leaves) in the 

 spring and these fall off with the leaves in autumn after the fruits have dropped. A heavy- 

 bearing, grafted variety from Chingchoufu, Shantung, China, sent in by Rev. W. M. Hays in 

 1911. Photographed (P593FS-C) at Chico, Cal., October 18, 1915.
