level, and this way of growing in hanging sheets 

 is in itself a very interesting characteristic, point- 

 ing to the use of many beautiful things in circum- 

 stances that could not otherwise be dealt with so 

 satisfactorily. 



The Rock Pinks and their hybrids are very im- 

 portant wall-plants of the hanging class. The hy- 

 brids for such use are derived from Dianthus ccesius 

 (the Cheddar Pink), D. plumarius, D. superbus, D. 

 fragrans, and possibly others. D. fragrans and its 

 double variety are delightful wall-plants; the double 

 is that wonderful tiny white Pink whose scent is 

 like the quintessence of that of Jasmine ; a scent 

 almost too powerful. Seed of these hybrids can be 

 had by the name of Hybrid Rock Pinks ; it is easily 

 grown and yields interesting varieties, all capital 

 wall and rock plants. 



The Rock Pinks are equally happy in a wall in 

 sun or shade ; but as we are just now considering 

 the plants that will bear the hottest places, among 

 the most important, and at the same time the most 

 beautiful, will be some of the tender Campanulas 

 of Southern Italy, and others that are usually found 

 tender or difficult of culture in England. Campanula 

 garganica, a native of rocks and walls in that curious 

 promontory of Gargano that stands out into the 

 Adriatic (the spur on the heel of Italy), is often an 

 uncertain plant in our gardens. But planted in a 

 cleft in very steep, almost wall-like rock-work, or 

 still better in an actual wall in the hottest exposure, 

 where it cannot surfer from the moisture that is
