As an informal hedge, screen or border, American Arborvitae is most 
satisfactory because of its dense growth 
American Arborvitae 
(Thuya occidentalis) 
HE American Arborvitae is the mother tree from which upward of 
fifty distinct types have been developed, varying in color from deep 
green to bright golden and ranging in size from little dwarfs to tall, 
pyramidal specimens. It likes a sunny location but will stand some shade. A 
moist location is preferred. Stands trimming well, and for this reason is widely 
used for hedge purposes. The rate of growth and ultimate height depend 
largely upon conditions. It usually grows bushy at the bottom and tapering 
toward the top. 
Trees of this genus are of ancient origin, it having existed throughout the 
northern hemisphere in early periods of the earth’s history. Its introduction 
into American gardens took place at the beginning of landscape development 
in America. It was probably the first American coniferous tree cultivated in 
Great Britain, having been introduced prior to 1597, in which year it was 
mentioned by Gerrard in his “Historie of Plants.” 
The foliage is flat, arranged in sprays of lacy dark green, pungent scale- 
like leaves. 
Ware Arborvitae 
(Siberian) 
(Thuya occidentalis Wareana) 
HE name Siberian has been given to it because of its rugged constitu- 
tion. A symmetrical, compact grower, very long lived. 
Raised by and named for Mr. Thomas Ware, an English nursery- 
man, who produced it about 1850. It matures at 6 to 8 feet. It is conical in 
outline and covered with dark green foliage which is somewhat different from 
the American Arborvitae, being much heavier and deeply crested. The 
branches are short and stiff. It is much used for foundation planting and 
frequently for hedges. 
It has a great advantage not possessed by most other varieties of the 
arborvitae family. It keeps a good green winter color.
