Cult. The species of Zanthoxylum will grow freely in sandy 

 loam ; and cuttings will root, if planted in a pot of sand, and 

 placed under a hand-glass ; those of the stove species in heat. 

 The hardy species, or those native of North America, will thrive 

 in any common garden-soil ; they are well adapted for ornament- 

 ing small shrubberies. Ripened cuttings of these will root, if 

 planted under a hand-glass, or they may be increased by slips of 

 the roots ; if planted in pots and placed in a hot-bed, they will 

 grow up to young plants.
