Colorado Blue Spruce (Picea Pungens Glauca). 
Considered by many the most beautiful of all the spruces. This tree 
is perfectly hardy and will withstand heat, drouth and cold. For best 
results Colorado spruce should not be planted on poor, gravelly soil. 
Blue color most pronounced on new growth in early summer.

Norway Spruce (Picea Excelsa). 
A rapid growing tree, very desirable for shelterbelt and background plant¬ 
ing. The Norway Spruce is gaining in popularity and rightly so for 
it is not only a rapid grower, but a very hardy tree which will thrive 
in any soil except poor gravel and sand.

Koster Blue Spruce (Picea Pungens Kosteriana). 
This is a strain of Colorado Blue Spruce selected for outstanding color 
and propagated by grafting. For those who want outstanding color, we 
recommend Kosters. They are as hardy as the Colorado Spruce grown 
from seed and require the same soil conditions.
