GREEN ASH 



In Canada the green ash is distributed from the western portion of southern 

 Quebec westward along the St. Lawrence river valley to Georgian bay, also from 

 the west side of lake Superior throughout the southern portion of the three Prairie 

 Provinces. 



It inhabits the banks of streams and bottom lands but is sometimes found 

 growing on the uplands. It is a small tree, commonly 30 to 40 ft. in height and 

 rarely going over 50 ft. It forms a low, rounded head with a short, clear trunk. 





GREEN ASH 



yor/eA^ /or?ceo/aAa 



It is a fairly rapid-growing tree and very hardy, and on this account is exten- 

 sively used in the prairie towns and cities of Canada for street and ornamental 

 planting. 



The green ash is considered to be a variety of the red ash. It differs from this 

 tree mainly in the smoothness of its branches, leaves and stems. The winter buds, 

 too, are very nearly hairless. The leaflets are somewhat narrower and shorter, 

 and the fruit is often longer than that of the red ash. 



The wood of this tree is sometimes used as a substitute for white ash.
