SPRUCE. Colorado Blue, 50'-70'. Of slow, 
compact growth, perfectly hardy in the most 
exposed situations. The foliage of seedling 
trees varies greatly in color from green to beau¬ 
tiful steel blue or sage color in the finest speci¬ 
mens. Because of these variations, we have 
classified our Colorado Spruce as follows: 
Colorado Green. Dark, lustrous green foli¬ 
age with practically no trace of blue color. 
Colorado Tinted. Slightly tinted blue, but 
not sufficiently to be included in “blue” class. 
Colorado Blue. Includes different shades of 
blue. We grade each tree of this class sepa¬ 
rately, pricing each tree according to the size, 
shape, and color of that particular tree. 
COLORADO BLUE SPRUCE

prise the finest strain of Blue Spruce. 
Norway, 80'-100'. Of rapid growth and sym¬ 
metrical shape, making a good lawn tree and 
used also for screens and wind-breaks.
