B. Deciduous Trees and Shrubs. Trees used in gardens of this 

 kind must be the low-growing types with a compact habit of growth, 

 and the shrubs also must be types which will lend themselves readily to 

 the character of this kind of garden. It is hardly possible to define 

 in words the exact character which the shrubbery must possess in order 

 to be valuable for this type of planting. The trees and shrubs in 

 this group may be used with safety, and there are many other shrubs 

 which can be selected from other lists and used by experts.

C. Perennials. This group of plants forms one of the most 

 interesting phases of rock garden development. Most of these 

 perennials are either heavy in their texture of foliage, or very dwarf in

 congested spaces so often found in garden developments of this kind.
