mental purposes it ranks with the European variety except that it is not 

 so rapid in growth. The tree might be utilized for planting for commer- 

 cial purposes on wet soils, but the white cedar is more valuable for 

 such areas. 



COLORADO BLUE SPRUCE— fPiceo parry ana.) 



In Iowa this spruce is planted for ornamental purposes but has value 

 for shelterbelt planting as well. Desirable trees have almost a perfect 

 conical form and the foliage varies from green to a distinct bluish white 

 color. They are very much prized for decorative purposes. The tree is 

 hardy in all parts of the State. 



WHITE FIR (silver fir) — (AMes concolor) 



Like the blue spruce, the silver fir is planted only for decorative 

 purposes in Iowa. The trees are very symmetrical and the foliage has a 

 silvery white appearance which makes it highly prized for lawn plant- 

 ing. The tree is considerably less hardy than the blue spruce and should 

 not be planted in exposed, dry situations.
