PITTSVILLE, MARYLAND 13 
GLENN DALE AZALEAS 
The Division of Plant Exploration and Introduction at the 
Glenn Dale Plant Station began introducing, in 1941, a group 
of selected seedlings from their own crosses. We have been 
growing and propagating these plants since then and we are 
now offering them to the trade. 
The purpose of this breeding work was to obtain a class 
of winter-hardy Azaleas that would have as large and varied 
flowers as those of the ‘‘Indian Azaleas’’ which are not 
hardy in this section. Mr. B. Y. Morrison, who has been 
leading in this work, has done a wonderful job, not only in 
producing large size and varied colors but also has bred the 
hardiness into the plants. These plants are most interesting. 
The flowers run to over 5-inches across and include both self- 
colored and variegated. The plants are mostly excellent 
growers and do well here, and from all appearances will 
grow well in much colder sections. 
When I was told they had some blooms that would run 
over 5-inches across I could hardly believe it but, it is so. 
I have seen them, and I hope to offer some of the plants in 
another season or two. We only have a small quantity of 
some varieties, but hope to get all varieties distributed in 
as large an area as possible so we may have information as 
to how they grow generally throughout the country. If you 
get some of these we will appreciate knowing how they 
grow with you. We suggest you give these a trial. 
The following descriptions were furnished us by Mr. 
Morrison and are based upon the original material as grown 
at Glenn Dale, Maryland, and give as figures for heights 
those of the original plants, all between 15 and 20 years old, 
under normal development except for the removal of propa- 
gating wood during a two season period. 
The number following variety name is the Glenn Dale 
Station number. 
Sometimes when Azalea flowers are described as striped 
or flaked on white they will appear as a solid color. When 
this occurs the branch should be cut out. This seems inherent 
with the variety—not any fault of the nurseryman. 
Blooming dates are for vicinity of Washington, D. C. in 
a normal season.

feet. Leaves dark green. Flowers 2 to 4 in head, often 
grouped, 2”-2%” across, irregularly hose-in-hose, white 
with very few flakes of Spinel Pink. Garden effect white. 
Mid-April, early May. 
ALADDIN (160126). Very erect habit as in Kaempferi and 
almost as deciduous. Flowers 1 to 2 in head, but heads 
sometimes grouped; general color effect is light salmon 
pink: color, Geranium Pink, white at base of tube, blotch 
not conspicuous, few dots of Rose Color. Mid-April. 
ALIGHT (163942). Bush habit broad spreading, but prob- 
ably not more than to 5 feet in height. Leaves medium 
green. Flowers 1 to 3 in head, 2%” across, Spinel Pink
