' I "HE propagation of Rhododendrons is by no 

 -■- means difficult, although as yet it has been

 or inarching ; and new varieties are obtained from 

 seed. 



These various processes differ in no degree in the 

 case of this plant from the ordinary methods ; but 

 we will describe them briefly. 



LAYERS. 



By this means the best plants are raised, and it is

In its native swamps the Rhododendron roots
