130 ROCK GARDENING FOR AMATEURS 



It gives some trouble and slugs are especially fond of 

 it. It needs a level spot in the rock garden with plenty 

 of grit in the soil and an annual top dressing. It thrives 

 well in the moraine. Increased by division in July. 



C. stenocodon. A comparative novelty of much 

 beauty, having beautiful pale blue flowers of similar 

 shape to those of the Harebell. It should be put in 

 the moraine or in very stony soil. 



C. Zoysii (Zoy's Bellflower). This is an exquisite 

 rockery plant from Eastern Europe, of close growth, 

 and bears a profusion of narrow tube-like blue flowers 

 in July. Large plants often die off without apparent 

 cause. It must be zealously protected from slugs. Give 

 it a level spot on the rockery in loam, sand, and grit, 

 or put it in the moraine. It will grow in sun or shade. 

 Increased by division in July.
