Colorado Grown Nursery Stock 
§ OLORADO grown nursery stock has demon- 
strated 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 development, which pro- 
duces 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 
withstand 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 trans- 
planting far less hazardous. Nearly all the trees and 
shrubs listed in this catalog have been grown on the 
premises and are well ripened and thrifty. The excep- 
tions are Roses and Fruits. These are procured from 
growers in lower but northern latitudes for the reason 
that limited growing acreage renders their growing 
impractical. 
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.
