io8 Fitting Associations 



becoming, as it were, an integral part of it,, the moun- 

 tain climber knows full well. These notwithstanding 

 the good places of the rock garden know them all too 

 rarely. Granite rock or limestone is to them all the 

 same, though the sharper contrast comes of the first- 

 named association. They merit planting on a gener- 

 ous scale to mean anything at all. 



Then one feels sure that the plant of a Certain trail- 

 ing habit is often enough insufficiently in the mind of 

 the planter of the rock-garden. In the mind's eye are 

 those effective Campanulas, fragilis, Barrelieri and 

 isophylla varieties, which, a little tender or delicate, 

 perhaps, if planted on level areas, are probably rarely 

 considered for other positions. We know of their 

 success — limited, it may be, to southern or favoured 

 gardens — when planted in the dry wall, though the like 

 places of the rock garden rarely know themi Yet the 

 sharply falling gully between rocks suits them well. 

 They drape such places as few other plants can. 

 Drier and protected between rocks, their roots pene- 

 tra;ting into recesses behind, they are hardier. For 

 their late flowering and their colour they are alike 

 welcome. For garnishing difficult places they are 

 most desirable. Rooted cuttings put out in .spring 

 are the best. Where the above do not respond, C. pro- 

 fusion (both forms) should be tried. They are hap- 

 pier so than on level ground, and fill a gully with a 

 colour all too rare in August and beyond. } 



Quite of the highest ornament and utility for like 

 places is Edraianthus (Wahlenbergia) serpyllifolius, 

 whose imperial purple bells trailing down a miniature 

 ravine will cause any plant-lover to halt. It is alone ; 

 no other within its set or out of it can claim such dis- 

 tinction. It must be raised from seeds, however, and 

 the seedlings planted in spring in order that a good 

 growth may be insured. Gritty loam and leaf mould 

 should form the staple soi^, and with chosen bits of 

 weathered rock driven in here and there as planting 

 proceeds to fix soil and plants and make rugged the
