LANDSCAPE DESIGN 



cracks between the stones may soon become full of moss, and indeed, 

 where little traveled, they may be planted with very low-growing, rock- 

 loving plants. 



The restful green surface of turf paths, not offering much color con- 

 trast with other foliage, makes them especially suited both to broad 

 central open spaces, rather turf panels than paths, and also to the 

 most subordinate paths, merely ways to go among the flowers. The 

 upkeep cost of such paths is considerable, if the grass is kept smoothly 

 cut and the edges trimmed, as is true of all sod edges for flower beds, 

 for unless the flowers are kept back from the sod they overshadow it 

 and destroy it in places. When paths of different width and impor- 

 tance form parts of a pattern, this relative interest may be recognized 

 by the choice of their surfacing material. A path along a terrace 

 might be stone-paved, the main garden paths might be of gravel, and 

 the subordinate paths, among the flower beds, of grass.
