4 WALL AND WATER GARDENS 



any reason there cannot be a dry wall, it is better to 

 plant the slope with low bushy or rambling things ; 

 with creeping Cotoneaster or Japan Honeysuckle, with 

 Ivies, or with such bushes as Savin, Pyrus japonica, 

 Cistus, or Berberis ; or if it is on a large scale, with the 

 free-growing rambling Roses and double-flowered 

 Brambles. I name these things in preference to the 

 rather over-done Periwinkle and St. John's-wort, 

 because Periwinkle is troublesome to weed, and soon 

 grows into undesirably tight masses, and the Hyperi- 

 cum, though sometimes of good effect, is extremely 

 monotonous in large* masses by itself, and is so 

 ground-greedy that it allows of no companionship. 



There is another great advantage to be gained by the 

 use of the terrace walls ; this is the display of the many 

 shrubs as well as plants that will hang over and throw 

 their flowering sprays all over the face of the wall. 



In arranging such gardens, I like to have only a very 

 narrow border at the foot of each wall, to accommo- 

 date such plants as the dwarf Lavender shown in the 

 illustration, or any plant that is thankful for warmth 

 or shelter. 



In many cases, or even most, it will be best to have 

 no border at all, but to make a slight preparation at 

 the wall foot not apparently distinguishable from the 

 path itself, and to have only an occasional plant or 

 group or tuft of Fern. Seeds will fall to this point, 

 and the trailing and sheeting plants will clothe the 

 wall foot and path edge, and the whole thing will look 

 much better than if it had a stiffly edged border. 



I suppose the whole width of the terrace to be four-
