66 LANDSCAPE GARDENING 



we plant all * lie 1 trees, like tlie spruces, larch, Lombardy 

 poplar, fastigiate oak, etc., all low-growing spreading trees, 

 all trees with yellow foliage or those with purple foliage, by 

 themselves, we do not get as pleasing results as if a variety 

 of forms, colors, and sizes are used and are arranged in a 

 natural and artistic manner. In Fig. 27 we have a very 

 pleasing arrangement of large and small trees and shrubs, as 

 well as a pleasing blending of forms, each placed so as to 

 bring out the peculiar features and all producing a pleasant 

 picture. In Fig. 31 is illustrated the grouping of trees and 

 shrubs along the borders of a walk or a curved roadway, in 

 which vistas are left open. The larger and heavier trees 

 are grouped in the centre and the smaller ones around them. 



2. As in the arrangement for shelter or screens, so in 

 the ornamental groups the tallest trees and those most 

 spiry will be more pleasing if grouped in the centre 

 or background, with the lower, more rounded or graceful 

 kinds placed in order of size, keeping in mind, of course, 

 variety and contrast, and yet securing harmony of colors as 

 much as possible. Trees with very heavy or dark foliage 

 should not be planted by the side of those with light, 

 feathery or very fine foliage, but something of an inter- 

 mediate tone should be introduced between them. So a 

 very small tree should not be planted close up to one of 

 large size if its branches are carried high, but if the branches 

 come to the ground with a broad slope, as in Fig. 27, both 

 a distant and close planting will be pleasing. 



3. The trees having the greatest individual beauty should 

 be put in such position that their beauty will be enhanced 

 by having a good background or a good setting. Thus the 

 appearance of a purple-leaved beech will be improved if 

 planted in front of or in the angle formed by silver maples
