Hardiness and Ratings 
Since the majority of hybrids listed were origi- 
nally created in Great Britain, we are almost entire- 
ly dependent upon the Year Books of the. British 
Rhododendron Association for information on hard- 
iness and desirability. We are hopeful that the 
American Rhododendron Society will be in a posi- 
tion to publish their own ratings within the very 
near future and, when this information is forth- 
coming, it will be used to determine the merits of 
hybrids under our own climatic conditions. The Ar- 
boretum Foundation, Seattle, Washington, in their 
excellent publication “The Handbook of Rhodo- 
dendrons,”’ has shown the way by conducting a sur- 
vey of the comparative hardiness of a wide range 
of hybrids. By combining their findings with our 
own experience in the nursery we have indicated 
what we consider to be an estimate of the hardi- 
ness of the hybrids listed in our catalogue. 
SYMBOLS: The asterisks (*) preceding the varietal 
name indicates the rating of the variety in 
question. 
(A) Hardy and will stand full exposure. 
(B) Hardy but requires partial shade for 
best results. 
(C) Hardy along the coast and in sheltered 
Spots in inland gardens. 
F. C. C. First Class Certificate awarded by 
the Royal Horticultural Society. 
A. M. Award of Merit awarded by the Royal 
Horticultural Society. 
SIZES: Inasmuch as there is a wide variation in 
growth and habit among the new hybrids, 
we have not stated sizes, but, in most cases, 
the plants will be from 8 to 12 inches in 
height, branched, and in a few instances, 
budded. Where one price is quoted, it is 
assumed that only one size is available. In 
cases where higher prices are quoted, it in- 
dicates that larger plants are available. 
We have a selection of larger specimen plants 
from which to choose and also some of the better 
species in stock. We invite your inquiry regarding 
varieties and prices of these items.
