Douglas Fir 
Douglas Fir 
(Pseudotsuga douglasi) 
HERE are two distinct forms of Doug- 
las Fir—one the dark green, gigantic- 
growing timber tree of the Northwest- 
ern Pacific Coast area, and the other type 
from Colorado. The latter variety is the one 
recommended, both for its hardiness and its 
great beauty. 
The typical form of young trees is an open, 
broad, sharp-pointed pyramid; the lower 
branches are straight or somewhat drooping, 
and the middle or higher ones trend upward. 
It is a tree which does exceptionally well over 
a large part of the United States, except in 
the extreme south. 
Tt is not uncommon to find an old speci- 
men sixty feet or more, with a spread of 
branches up to twelve feet in diameter. The 
tree has a very commendable habit of re- 
taining its lower limbs in old age, which 
attribute greatly adds to its beauty. 
It is a rapid grower and has long, graceful 
branches, less stiff than the Spruce. The foli- 
age is not sharp and stiff, but soft, flexible, 
and also fragrant. It seems to thrive 
under conditions of shade better than most 
trees of this type and will stand consider- 
able crowding. 
The value of Douglas Fir as an ornamental 
tree can hardly be overstated. It is an out- 
standing tree.

Concolor Fir. (1/2 natural size) 
Concolor or White Fir 
(Abies concolor) 
ONCOLOR FIR grows in its native range 
over a considerable north and south area 
in the Rocky Mountains, trees of the 
most desirable habit, color, and hardiness come 
from Colorado. 
There is some variation in the color and the 
foliage of the Concolor Fir. Many trees are of a 
decidedly bluish color; others are green. Trees 
planted in ornamental plantings generally do not 
reach more than fifty or sixty feet, with a con- 
siderable spread of branches, perhaps as much as 
ten to twelve feet. When fully established, how- 
ever, they carry a beautiful, even spread of 
branches and are one of the most beautiful of all 
Evergreens of this type. 
Concolor Fir is useful in landscape work in 
various ways, as single specimens, screens, heavy 
borders and wind breaks. 


“In fact, there's nothing that keeps its youth, so far as 
I know, but a tree, and truth.”
