I SHADE AND ORNAMENTAL TREES EOR PLANTING IN ARIZONA 



Deciduous and evergreen trees listed below will succeed ordi- 

 narily in those sections of the State which fall within the altitude 

 limits given, the (X) indicating successful growth. These altitude 

 limits are necessarily arbitrary and have been chosen for con- 

 venience. A few of the tender evergreen species will be injured 

 with extraordinary freezes at the uppermost limits named, and a few 

 of the high mountaia evergreen species may be found to grow with 

 cultivation at altitudes lower than those suggseted. For further 

 information concerning resistance of our cultivated trees to frost 

 and for detailed information relative to the cultivation of these 

 trees, see Timely Hints for Farmers, Nos. 62, 68, 79, 83, and 91.
