250 ROCK GARDENS 



C. car. pelviformis. — A more distinct variety, and one of the best. 

 Grows as high as i8 inches, and bears a profusion of large, rather 

 flat, saucer-shaped flowers of a pleasing shade of pale blue. Not 

 quite as robust as some of the other kinds. Slugs, therefore, are 

 rather devoted to it. 



C. car. " White Star:'—La.Yge, saucer-shaped flowers, nearly 2^ 

 inches across, white, with just a trace of blue in them, which, if 

 anything, rather enhances their beauty. 



C. cenisia. — Deep, very gritty, sandy soil. Spreads vigorously 

 underground, and above makes compact rosettes of light green 

 leaves. Grows only about 3 inches high, with funnel-shaped, solitary 

 blue flowers. Division. 



C. collina. — Likes a hot, stony bank. Greyish, downy leaves of 

 medium growth. Pendulous, long, funnel-shaped flowers of the 

 most beautiful violet colour, rivalling C.pulla in intensity. A lovely 

 and uncommon plant of the easiest culture. Quite one of the gems 

 of the genus. 



C. Elantines. — Of trailing habit, with hairy leaves and blue 

 starry flowers, rather flat-shaped. Dislikes damp, and should be 

 planted in a crevice in full sun. Slugs are very devoted to this 

 species. 



C. excisa. — Open position in gritty peat and loam. A rapid- 

 growing little plant of spreading habit. Thin, erect stems, 3 to 6 

 inches high, and drooping, bell-shaped flowers of pale violet. It 

 derives its name from having a small round hole at the base of 

 every lobe. A charming little plant. Does not like lime. Increased 

 by division. 



C. /r^^//?y— Requires well-drained, sandy loam, as it dislikes 

 excessive moisture. Prostrate, trailing habit, barely 5 inches high. 

 Rather large, pale, clear lilac-blue, bell-shaped flowers, with a white 

 centre, borne on half-prostrate stems. The stems of this plant are 

 very brittle, from which it derives its name. A very pretty little 

 plant. 



Other Campanulas very nearly allied to and requiring much the 

 same treatment as fragilis are Barrelieri^ Balchiniana^ rupestris^ 

 and Tenorii. These are all so much alike that to the ordinary 

 gardener, at least, it is very hard to distinguish one from the 

 other. 



C. garganica.—VrosXxdX^^ compact habit, and free-growing. 

 Toothed, heart-shaped leaves. Plant covered in summer with a 

 profusion of bluish starry flowers, with a white centre, rising about 

 3 inches. One of the best and easiest-growing Campanulas. Should 

 be planted in crevices in vertical parts of the rock garden to show it 

 at its best. Easily increased by division or seed. Alba is a white 

 and lovely form.
