ABOUT OUR RHODODENDRONS 
The rhododendrons of Asiatic and European origin, offered in 
the following list, have been raised fram seed that came directly 
from the Royal Botanic Gardens of Scotland and Bngland. Care has 
been exercised to assure their accuracy of identification and high 
quality. 
The species are listed alphabetically under their respective 
series. The heights given indicate the maximum size that the plants 
may be expected to attain. The months indicate the approximate time 
of bloom. 
The 1-4 asterisks (x) indicate the rating assigned by the 
Rhododendron Association, 4 asterisks meaning the most choice. Many 
kinds that are without asterisks may be very lovely and desirable, 
Bpecies but because of their scarcity or recent introduction are not 
yet well enough known to have been assigned a rating by the assocta- 
tion. It Should also be kept in mind that individual tastes differ 
in regard to the quality that constitutes beauty or desirability in 
plant life. 
The capital letters indicate the hardiness of rhododendrons as 
applied to the British Isles, and published on p. 86 ofthe Rhododen~ 
dron Association's last year book, as follows: (A) Hardy anywhere in 
the British Isles and may be planted in full exposure if desired, 
(B) Hardy anywhere in the British Isles but requires some shade to 
obtain best results. (C) Hardy along the seaboard and in warm gardens 
inland. (D) Hardy in south and west but requires shelter even in warm 
gardens inland. (EH) Requires shelter in most favored gardens, 
(¥) Usually a greenhouse shrub. 
The hardiness of the various species under the numerous types 
of climatic conditions found in the United States, has not been 
fully determined. Information concerning the hardiness and blooming 
time of any Species being grown in your particular locality will be 
greatly appreciated. The gathering together of such information 
Will be a real contribution toward the progress of rhododendron grow- 
ing in this country.
