14 Making a Garden of Perennials 



plants. In other words, you increase your 

 width in jumps of eighteen inches at a 

 time. While this is not actually necessary, 

 it is best and applies only to the widest 

 and narrowest points. The intervening 

 curved lines will vary from this measure- 

 ment but it makes no difference, because 

 you do not plant in straight rows from 

 back to front as one would cabbages. 



In planting at boundary lines or at 

 buildings, the taller ones should be used 

 at the back, but the semi-tall ones say 

 three feet in height should occasionally 

 be brought well toward the front in order 

 .to avoid stiffness and to add irregularity 

 to the general effect. If a house or fence 

 is at the back, flowering vines like the 

 Clematis paniculata, or C. flammida, or 

 any annual flowering vine, may be used 

 here and there. In detached beds which 

 may be seen from all sides, the taller plants 

 are set in the middle. 



The effect is much better if you plant in 

 groups of four, six, or more of one kind.
