ALPHABETICAL LIST OF PLANTS 249 



tinguishable from one another, that it would be impossible to give 

 anything like a complete list ; but the following kinds are the 

 best and most distinct forms, dwarf of habit, and well suited for 

 the rock garden. Unless otherwise stated, it may be understood 

 that sandy loam and sun are what they require. 



C. Abietina. — Close green mats of leaves, 2 inches high. Lovely 

 open, star-shaped, purple flowers in May, on slender, erect stems 

 about 6 inches high. Increased by division, which it requires 

 occasionally. One of the best kinds. 



C. Allionii (syn. C. alpestris and C. nana). — Small stone chips, 

 with a dash of peaty soil, in sun, are the needs of this plant, which 

 hates lime. Long, narrow, hairy leaves and blue, bell-shaped flowers 

 on slender stems about 6 inches high. Blooms in July. One of 

 the loveliest and most difficult Campanulas. Requires abundant 

 moisture during growing season. 



C. alpina. — Rather long leaves covered with a greyish down. Of 

 erect habit, growing from 6 to 10 inches high. Spikes of fine dark 

 blue flowers, pendulous, tubular-shaped, about i inch long. Blooms 

 in July. Division or seeds. 



C. barbata. — Compact tufts of shaggy leaves. Lovely pendulous, 

 pale blue, bell-shaped flowers nearly i inch long, all fringed at the 

 mouth. These are borne four or five on a spike, in May. Un- 

 fortunately not always perennial. Rather dislikes excessive damp 

 in winter, so should be planted in a dryish spot. 



There is also a lovely form, alba^ which requires the same 

 treatment. Both come readily from seed, and are among the 

 choicest of the genus. 



C. caespitosa.— h. dwarf, spreading little plant. Tufted habit, 

 growing only 4 to 6 inches high. Round glossy leaves and a 

 cloud of lovely pale blue flowers during the summer. So well does 

 it thrive and spread that it should not be associated with the very 

 choicest plants ; but for planting between steps and clothing odd 

 corners there is no better or more lovely little flower. Readily 

 increased by division. There is a white form, which is difficult to 

 distinguish ixom. pusilla alba. 



C. carpatica. — Erect, deep blue flowers, funnel-shaped, growing 

 in loose panicles about 9 to 18 inches high, according to the rich- 

 ness of the soil, and very freely produced during the summer. 

 Stems leafy and branched. This is the type, but there are an 

 endless number of hybrids and varieties ; of the latter the best 

 and most distinct are — 



C. car. alba. — A pure white form, very lovely. 



C. car. pallida. — Palest of blue flowers. 



C. car. riverslea. — A good and very free-blooming and vigorous 

 variety, with deep blue flowers.
