ZIZYPHUS 



and none of the species is hardy north; the hardiest 

 seems to be Z. vulgaris, but it is tender north of Wash- 

 ington, D. C. Most kinds have handsome foliage and 

 are well adapted for planting in shrubberies in the 

 southern states and California. They seem to thrive in 

 any well-drained soil. Prop, by seeds, by greenwood
