CAMPANULA 127 



on slender stems five or six inches high ; it forms 

 a dense little tuft. It flourishes in light soil on rock- 

 work or in the moraine. Increased by division or 

 seeds. 



C. tridentata (synonym C. Saxifraga trident ata). This 

 Bellflower grows well, and is not nearly so troublesome 

 as its choice appearance would suggest. It is of tufted 

 growth, and bears rather large violet bells in July. It 

 grows readily in gritty soil, and is quite a success in the 

 moraine. 



C. Waldsteiniana (Waldstein's Bellflower). This 

 plant, which is native of Hungary, has upright and star- 

 shaped blue flowers on short stems. It does well in a 

 cool part of the rock garden in gritty loam, and leaf- 

 soil, or in the moraine. 



THE MORE DIFFICULT CAMPANULAS 



C. Allioni (Allioni's Bellflower). An unusually charm- 

 ing dwarf plant from the Alps of Italy ; it thrives best in 

 the moraine. It will also grow in the crevices of a sunny 

 wall built without mortar, or on a sandstone or granite 

 rockery with plenty of stones and chips about it. The 

 pale blue tube-shaped flowers open in July. Increased by 

 division after flowering. 



C. alpina (Alpine Bellflower). A choice rockery 

 plant found on the European Alps ; although perennial, 

 it is apt to flower itself to death, and should be frequently 

 raised from seeds. It is about six inches high, and has 

 large blue, fringed, bell-like flowers in July. Grow on
