The SPRUCE, Picea, are majestic 
and sturdy trees, with emphatic 
pyramidal forms. Above is showna 
branch of COLORADO BLUE 
SPRUCE, Picea pungens glauca, 
with its tight foliage of frosty blue. 
These trees are well adapted to con- 
ditions of extreme exposure, whether 
on the seashore or bleak hillside. 
The WHITE FIR, Abies concolor, 
has a distinct pyramidal form and 
attains a considerable height. It is a 
pleasant and not too common accent 
in the landscape.
