146 THE COMPLETE GARDEN 



C. GROWING IN TUBS. One of the most successful sources of 

 obtaining refinement of detail in formal work is through the use of 

 plants grown in tubs. These are particularly adapted to terraces, areas 

 around pools, and places where plants must be trained for a specific 

 detailed effect, and oftentimes cannot be planted in the ground at the 

 place where the effect is desired.

D. TREES AND SHRUBS FOR ALLEES. All plants which are adapted 

 to allee effects must be of a type which will respond to the operations 

 of severe pruning. Those plants in Group a must have a special 

 adaptation for a spreading habit of growth and yet a compact habit of 

 growth. They must be such plants as will retain their foliage during a 

 considerable period in order to produce and maintain the pleached 

 allee effect. The deciduous and evergreen trees and shrubs shown in 

 Group b of this list are all adapted to types of open allee developments 

 on different scales, to be in keeping with the general landscape effect.
