Hardiness, Ratings and 
Flowering Period 
HARDINESS: Since the majority of hybrids listed 
were originally created in Great Britain, we 
are almost entirely dependent upon the Year 
Books of the British Rhododendron Associa- 
tion on hardiness and desirability. We are hope- 
ful that the American Rhododendron Society 
will be in a position to publish their own rat- 
ings within the very near future and, when this 
information is forthcoming, it will be used to 
determine the merits of hybrids under our own 
climatic conditions. The Arboretum Founda- 
tion, Seattle, Washington, in their excellent 
publication “The Handbook of Rhododendrons”’ 
has shown the way by conducting a survey of 
the comparative hardiness of a wide range of 
hybrids. By combining their findings with our 
own experience in the nursery we have indi- 
cated what we consider to be an estimate of 
the hardiness of the hybrids listed in our cata- 
logue. 
(A) Hardy and will stand full exposure. 
(B) Hardy but requires partial shade for best 
results. 
(C) Hardy along the coast and in sheltered 
places in inland gardens. 
Eastern Customers Please Note 
We have been in correspondence with numerous 
customers located in the warmer areas of Long 
Island and southward through the more temperate 
regions of Delaware, Maryland, Virginia, the Caro- 
linas, and Georgia. From their reports, we judge 
that varieties which are marked “A” and “B” in 
our catalogue would succeed in the aforementioned 
localities. Prospective customers are invited to write 
us for information regarding the varieties most 
suited for trial in their gardens. 
RATINGS: The asterisks (*) preceding the varietal 
name indicates the rating of the variety in 
question. Where there are no asterisks preced- 
ing the varietal name, it indicates that it is too 
new to be rated. 
FLOWERING PERIOD: The fowering period varies 
somewhat from year to year therefore we have 
indicated the time of blooming by season e. g. 
early, mid-season, and late. The early season 
would be in April, the mid-season in May, and 
the late in June with some overlapping from 
month to month,
