Colorado Qrown Rursenj Stock 
OLORADO grown nursery stock has dem¬ 
onstrated over and over again its superior 
merit and adaptability to severe and trying 
locations and situations. 
There are several reasons for this, among 
which are altitude and therefore slower develop¬ 
ment, which produces a harder wood fibre. Trees 
and shrubs in high altitudes ripen and shed 
their foliage much earlier than in lower altitudes 
and warmer climates, thus enabling them to enter 
the winter period in better condition to with¬ 
stand its rigor. Another important factor is that 
our climate is practically rainless during the 
growing season. An irrigation system supplying 
the water needs, develops a wonderful root action, 
rendering the transplanting far less hazardous. 
Nearly all the trees and shrubs listed in this cata¬ 
log have been grown on the premises and are well 
ripened and thrifty. The exceptions are Roses and 
Fruits. These are procured from growers in lower 
but northern latitudes for the reason that lim¬ 
ited growing acreage renders their growing im¬ 
practical. 
Perhaps a word of warning is not out of place. 
Trees and shrubs should be purchased only from 
nurseries which have been inspected and certified 
by proper authorities as being free from injurious 
insect pests and diseases — or from persons who 
procure their stock from inspected nurseries. 
Otherwise the purchaser may be buying infested 
or infected stock, which may later have to be 
destroyed.
