62 WALL AND WATER GARDENS 



Valerian must be considered and allowed for as well 

 as the down-drooping of those that make hanging 

 sheets. So also the neat stay-at-home habit of Thrift 

 will be taken into account, and the way of running 

 along a joint of Polypody and Campanula ccsspitosa. 



From March to May, or just after they ripen in the 

 autumn, seeds are put in mixed with a little loamy earth, 

 and if the cleft or opening is an upright one, unwilling 

 to retain the mixture, a little stone is wedged in at the 

 bottom or even cemented in. For a plant of rather 

 large growth, like V2XQ,v\2in{Centranthus),2i whole coping 

 brick can be knocked off the top, and probably quite 

 a nice rooting-place be made with the downward- 

 digging chisel, to be filled up with suitable soil. 



By some such means, and always thinking and 

 trying and combining ideas, the plainest wall can in a 

 couple of years be so pleasantly transformed that it is 

 turned into a thing of flowery beauty. There is no 

 wall with exposure so hot or so cold that has not a 

 plant waiting for just the conditions that it has to oiifer, 

 and there will be no well-directed attempt to convert 

 mural ugliness into beauty whose result will not be an 

 encouragement to go on and do still better.
