E. Perennials Seldom Used in Small, Refined, Formal 

 Gardens. This group contains a few types which should be con- 

 sistently avoided in the development of a small, formal flower garden, 

 where refinement of detail is the main requirement. These plants, 

 when not given careful attention, such as staking and constant cutting 

 back, will produce a loose, ragged effect and will crowd out many of 

 the small types of perennials which are admirably adapted for use in 

 small formal flower gardens.
