176 LANDSCAPE GARDENING. 



purple or bronze-green foliage all summer, is moderately 

 vigorous in growth, and very desirable. 



GOLDEN-LEAVED OAK (Q. r., var. concordia). This is 

 perhaps tlie best of the golden-leaved oaks, and is very 

 beautiful when the leaves first unfold, but it loses some- 

 thing of its freshness and beauty as the season advances. 

 Its chief value consists in the use that may be made of it 

 in toning down the extreme shades and tints of other trees. 



GOLDEN-LEAVED JAPANESE MAPLE (A. Jap.^aurea). 

 A most beautiful tree for planting with the purple-leaved 

 forms of A. polymorphum.
