Rhododendron Species 
The following Rhododendron species have been selected because of their 
value as ornamental shrubs and, with the possible exception of R. repens and 
R. Williamsianum, they are as easy to grow as the hybrids. However, at the risk 
of discouraging a prospective customer, I would say that species are for the 
advanced amateur or collector who has now gained an appreciation of the wild 
types from which our hybrids have been derived. Personally, I get as much en- 
joyment out of growing the species as I do the hybrids, for the foliage and floral 
characters are so varied and full of interest. 
All of the plants listed below are grown from seed with the exception of 
those marked “clone”. A “clone” is a plant which has been propagated from a 
cutting, graft, or layer, and is actually a part of the original selected form.
