A very large and familiar tree (fifty to eighty feet 

 high), one of the largest of the Willows ; low-branching ; 

 thick-set, of tough and rapid growth. A stake set in the 

 ground grows readily. The silvery look of the tree 

 (especially in a strong wind) is due to the gloss of its 

 downy leaves. 



The Blue Willow [van cserulea S.] is naturalized in 

 Massachusetts.
