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 c&spitosa. 



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 Valerian (Centranthus), a 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 offer, 

 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.
