150 PLANNING AND PLANTING 



ficial, and to simulate as closely as possible the 

 rough, rugged, irregular workings of Nature. 



There are ambitious rock gardens that occupy 

 several acres of space, and are spots of remark- 

 able beauty ; others are quite miniature, and withal 

 very beautiful if arranged with taste and judg- 

 ment. 



Such a chapter as this would be incomplete were 

 we not to give a list of some of the plants suitable 

 for rock garden planting, and in doing so we will 

 divide them into two groups. The first will be of 

 plants that grow only one to six inches in height, 

 and the second group will be of types showing from 

 six to twelve inches tall. The plants we list in 

 this chapter are all hardy. 



In giving a list of names it will be necessary to 

 identify certain of the plants by their Latin names 

 to avoid possibility of error in selecting your 

 plants. For instance, if we were to list simply 

 Campanula, you might get Campanula persicifolia, 

 growing two feet high, or one of the other types 

 unsuited to your purpose, when you really should 

 have the Campanula gargantica or carpatica, 

 either of which is dwarf. 



So we will list the following sorts of your selec- 

 tion. Alyssum saxatile (Gold Dust) , yellow ; acqui- 

 legia corulea (Columbine), blue; ajuga reptans 

 rubra (Bugle), blue; arabis alpina (Rock Cress), 

 white; campanula gargantica, blue; gypsophila
