A GARDEN OF WALL-FLOWERS 37 



keep it. C. Marshalli never forms seed, and I have not 

 seen it on C. mutahilis. A few other plants would be 

 admitted to the Wall-flower garden, such as yellow 

 Alyssum on sunny banks and Tiarella in cool or half- 

 shady places, and in the wall -joints I would have in 

 fair quantity the beautiful Corydalis capnoides, most 

 delicate and lovely of the Fumitories. Leading to the 

 Wall-flower garden I should like to have a way between 

 narrow rock borders or dry walls. These should be 

 planted with Aubrietias, varieties of A. grceca, of full 

 and light purple colour, double Cuckoo-flower in the 

 two shades of colour, and a good quantity of the grey 

 foliage and tender white bloom of Cerastium tomen- 

 iosum, so common in gardens and yet so seldom well 

 used ; I would also have, but more sparingly, the all- 

 pervading Arahis albida. 



These plants, with the exception of the Cuckoo- 

 flower, are among those most often found in gardens, 

 but it is very rarely that they are used thoughtfully 

 or intelligently, or in such a way as to produce the 

 simple pictorial effect to which they so readily lend 

 themselves. This planting of white and purple colour- 

 ing I would back with plants or shrubs of dark foliage, 

 and the path should be so directed into the Wall-flower 

 garden, by passing through a turn or a tunnelled arch 

 of Yew or some other dusky growth, that the one is 

 not seen from the other ; but so that the eye, attuned 

 to the cold, fresh colouring of the white and purple, 

 should be in the very best state to receive and enjoy
