THE COMPLETE GARDEN 



and the wild pink are considered to be true crevice plants, and they 

 should be used only for that purpose in rock garden work. These 

 plants have a type of environment equally as much as persons or 

 animals and under which they thrive best. The beginner who is 

 developing this type of garden should therefore only use the more 

 common types of plants which have withstood the abuse of " amateurs " 

 and should make use of the specialized plants only after a thorough 

 knowledge is gained concerning them. 



One writer has said concerning the development of a rock garden 

 that the designer should "have an idea and stick to it." We see so 

 many rock gardens which are so-called and which in reality are only 

 a miscellaneous pile of stones. Rock gardens in their true sense 

 are an imitation of some condition of nature, both from their physical 

 makeup and from their planting. We should therefore make a 

 double effort to strive toward the development of the idea. 



One of the most successful ways for obtaining good rock garden 

 plants is to grow them from seed. It is often easier to seed plants 

 in rock garden groups than it is to plant nursery-grown stock.
