LANDSCAPING 
With the increase in number of Rhododendron hybrids, the 
gardener has been allowed a great deal more latitude in his 
choice of suitable locations for their culture. Dwarf types such 
as Carmen, Moonstone, Humming Bird and pemakoense are ex- 
cellent subjects for the rock garden where they will thrive 
provided they are not planted on a south facing slope in full 
sun. Low informal hedges of Bowbells, Cilpinense, or Blue Tit 
would make attractive boundaries between garden areas. The 
Lady Chamberlain varieties and related types make wonderful 
specimens when trained flat against a protected wall. The taller 
growing sorts, as Betty Wormald, Sappho, or Mrs. Chas. Pearson, 
could be utilized as screen plantings or as background material 
for the large border. The low growing varicties, as May Day, 
Fabia, Unique and Bowbells; are supplying a long needed change 
in foundation plantings, and landscape architects are using them 
to good advantage on east and north aspects, or on the south 
and west when shade conditions warrant their use. 
In the woodland garden the lavenders, blues, and mauves are 
most effective and varieties as Mrs. Chas. Pearson, Van Nes 
Sensation, Mrs. E. C. Stirling, and the forms of Augustinii show 
to advantage when shaded from direct sunlight. There are va- 
rieties suited to the smallest city garden or the largest country 
estate. The color range is almost complete, and includes creams 
and yellows, lavenders and blues, pinks in every shade, reds, 
crimsons, and scarlets and all the intermediate blends. Where 
Rhododendrons can be grown they stand unsurpassed as orna- 
mental flowering shrubs on equal terms with the rose in beauty 
and popularity. 
HARDINESS 
The hardiness of any plant is determined by many factors 
all of which are interrelated. Inheritance, vigor, available mois- 
ture, amount of protection afforded, condition of growth, time 
of year low temperatures occur, cultural practices of the grower 
and many more. 2 
The majority of the hybrids listed in this booklet are of 
British origin and, until last year, we have been entirely depend- 
ent upon the Year Books of the British Association for ratings 
on hardiness and desirability. The American Rhododendron 
Society has recently published their ratings and the two sys- 
tems have been incorporated into our descriptive matter so 
that the prospective grower may evaluate his climatic conditicns 
and select his varieties accordingly. 
Several of the varieties in the lists have not been given a 
rating by either the American or British Associations and in 
these instances the plants are too new to be rated. However, all 
of them are comparable to the B Class which means that they 
are at least hardy to 5 degrees above zero. Whatever is selected, 
it is extremely important that the following ruics be observed: 
1. Begin with healthy plants. 
2. Maintain a deep mulch of loose substance over the 
root area. 
Do not allow the plants to enter the winter ina 
dry condition.

HARDINESS AND QUALITY RATINGS 
The symbols which follow the variety names are significant in that they represent the hardiness and quality ratings 
of the British and American Rhododendron Societies. Frem these symbols, the customer is able to determine with 
reasonable accuracy the varieties best suited to his cllimate. 
The British Ratings are as follows: 
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. 
The asterisk (*) following the letters A, B or C indicate 
the quality rating of the variety in question. Four asterisks 
signifies top rating. Where there are no asterisks it means 
that the variety is too new to be rated. 
The symbol “x” following the letters H-1, H-2, etc., in- 
dicates the American quality rating, Four “x’s” indicate the 
NEW

CARMEN (didymum x repens) 
A new introduction of great merit which has received 
many awards in Great Britain. This is a true dwarf, form- 
ing cushions of dark green rounded leaves and waxy crim- 
son bells which appear in April. Unlike its parent, R. 
repens, it is easy of cultivation. Very scarce. We have a 
limited number to offer this year for the first time. 
2"-4" $4.50; 4"-6" $6.00 
DAMOZEL (A. W. bright rose x Griersonianum) 
An attractive hybrid created by the late Lionel de Roths- 
child. The large dome shaped truss contains 17 flowers 
which are a deep rose pink with darker spots throughout 
the interior. Really a beautiful variety which blooms to- 
wards the end of May 9"-12" $7.50 
ELIZABETH (repens x Griersonianum) 
This is without doubt the most notable introduction from 
Great Britain in years. It excels either parent in beauty 
and is exceptionally free flowering. Perhaps it’s most com- 
mendable character is its ease of cultivation. The habit is 
more spreading than upright and it should eventually at- 
tain a height of 2% feet but with a greater corresponding 
width. The trusses, comprising clusters of three to six 
blossoms, are axillary as well as terminal. The flowers are 
3 inches wide, 2% inches long, deep red, and appear in 
late April. A wonderful low growing hybrid with great 
promise. Scarce. 4"-6" $6.00; 6-9" $7.50 
GRENADIER (Moser’s Maroon x Elliottii) 
This is a first class hybrid created by the late Lionel de 
Rothschild. It has an erect habit, possibly attaining a 
height of 8’. The foliage is dark green and the perfectly 
round tight trusses comprise about 17 flowers which are 
individually 3% inches in diameter and an intense blood 
INTRODUCTIONS FOR 
Stock of these plants in this group is exceedingly scarce, therefore, we are limiting our sales to one plant per 
customer. Since in many instances only a few plants are available this year, we urge that orders be placed early to 
The American Ratings are as follows: 
H-1 These varieties should be hardy in Southern 
New York and Southern New England. 
H-2 & H3 These varieties should be hardy in the south- 
ern part of Long Island and around Phila- 
delphia. 
H-4 & H5 These should be hardy close to the coast in 
Pacific Northwest or in sheltered areas 
throughout Western Washington and Oregon.

that the variety is too new to be rated.

red. The blooms appear in late May. Highly recommended 
as one of the best late reds. 9"-12" $7.50 
IMPI (didymum x Moser’s Maroon) 
Hardy and distinctively dark in color. This little fellow 
has miniature trusses of bell shaped flowers. In the shade 
the flowers appear black but are brightened by sunlight to 
a brilliant red. The lance shaped leaves are dark green 
with a conspicuous white indumentum beneath. Will be- 
come a small compact shrublet 3 feet high and blooms in 
April. 6-9" $6.00 
JOCK (Williamsianum x Griersonianum) 
An excellent small hybrid of notable ancestry. Well suited 
where space is limited and makes a low spreading shrub 
with rounded leaves and dainty trusses of 6 to 8 flowers. 
The blossoms are bell shaped, dark pink with a suggestion 
of orange in the throat, and appear in late April. One of 
the best. 6'-9" $6.09 
RACIL (racemosum x ciliatum) Bee 
A happy combination of two fine species with clusters of 
apple blossom pink flowers. It forms a neat low shrublet, 
possibly 3 feet at maturity, and has survived below zero 
temperatures at our nursery. The flowers usually appear 
in early April. This charming dwarf should be planted in 
groups of 3 or more to be appreciated. 
6"-9" $5.09; 9-12" $7.00 
RADIUM (Griersonianum x Earl of Athlone) 
When first we saw this hybrid in bloom it reminded us of 
a giant peony. The dome shaped trusses contain from 14 
to 16 flowers of bright geranium scarlet. The substance 
is excellent and the flowers are quite weather resistant. It 
should eventually attain a height of 6 feet and makes a 
dense rounded shrub. It blooms in late May. 97-12” $7.50
