124 ROGK GARDENING FOR AMATEURS 



C. glomerata (Clustered Bellflower). The taller varie- 

 ties of the British C. glomerata are rather too big for the 

 rockery, but the curious little variety named acaulis, 

 with heads of blue flowers set among the leaves in June, 

 is pretty. It grows best on the level, in any soil. In- 

 creased by division or seeds. 



C. haylodgensis. Among the several hybrid Cam- 

 panulas of trailing growth this is one of the best. It 

 has shining yellowish leaves and light blue flowers in 

 June, which last a long time in bloom. It is easily 

 grown in gritty soil, in sun or shade. C. Profusion 

 closely resembles this. There is a double variety of 

 C. haylodgensis. Increased by division or cuttings in 



July. 



C. Hostii (Host's Bellflower or Harebell) . This is 

 really a glorified form of the common Harebell (C. 

 rotundifolia), but much finer in every way, and with 

 bigger blooms in July. Easily grown almost anywhere. 

 The white variety, alba, is charming. Increased by divi- 

 sion after flowering. 



C. linifolia (Flax-leaved Harebell). This is closely 

 allied to the common Harebell also ; it is a pretty plant 

 with drooping violet blooms. There is also a white variety. 

 C. valdensis is a variety of this having greyish leaves 

 and bigger flowers. Easy anywhere, though preferring 

 a moist soil. Increased by seeds or division. 



C macrorhiza (Large-rooted Harebell). Obviously 

 closely related to the common Harebell, having small 

 flowers of a pretty lilac shade. It flowers very freely.
