40 STUDIES IN GARDENING 



ing less than 2 ft. high. It has large drooping white 

 bells, and can be easily raised from seed. Campanula 

 urticifolia is usually seen in the white double-flowered 

 variety. This is one of the few cases in which doub- 

 ling improves a campanula, and it is a very pretty 

 plant. C. glomerata is a British species and very 

 easily grown. It is only about a foot high, and the 

 flowers, of a rich violet colour, are crowded together 

 at the top of the stalk. The white variety is very 

 beautiful, but not so vigorous as the type. There is 

 also a new very dwarf form called acaulis, a good 

 plant for the rock garden. C. punctata is another 

 low-growing border plant, with white spotted flowers. 

 It often takes a year or two to establish itseK, and 

 then is apt to become a weed. Besides these are two 

 fine hybrids, C. Hendersonii and C. Fergussonii, both 

 of them, perhaps, being crosses between C. carpatica 

 and C. pyramidalis. They are both valuable and 

 distinct border plants growing about 18 in. high. 



We will pass now to the campanulas of inter- 

 mediate growth, most of them inhabitants of hill 

 countries or Alpine pastures, but most of them also 

 easily grown in the border. The English Harebell, 

 C. rotundifolia, is, of coiu-se, both a lowland and a 

 highland plant; and only its commonness prevents 

 it from being a favourite flower in our gardens. The 

 white form is rather rare, though often seen in Derby- 

 shire. It is less vigorous than the type, and often 

 dies if divided. C. Hostii is a variety of C. rotundifolia, 

 and scarcely to be distinguished from it except by
