Ceanothus. [Rhamnaceae.] Hardy or half-hardy ever- 

 green and deciduous shrubs, generally worthy of cultivation 

 in the shrubber}^ They are mostly of free growth and neat 

 habit ; flowers numerous and showy. Propagated either by 

 cuttings, which should be planted in sandy soil under hand- 

 glasses, or by layers, which is the readiest way of obtaining 

 strong plants. They are not particular as to soil, but grow 

 well in sandy loam, and, not being very hardy, the situation 

 ought to be a well-drained one. The Californian species 

 may be considered as hardy, in mild winters, south of Phil- 

 adelphia.
