PB ACTIO AL GUIDE TO GARDEN PLANTS campanula 



the upper portion of the stalks being much 

 narrower. 



Culture d-c. as above. When grown 

 in large masses this has a very pretty 

 effect in the rockery. It likes warm sunny 

 positions. 



P. hemisphaericum. — This dwarf spe- 

 cies grows in the crevices of the Alps 

 and Pyrenees, and is 2-6 in. high. Leaves 

 linear grass-like. Flowers blue, in rounded 

 heads on the top of straw-like stems and 

 surrounded by oval-shaped bracts. 



Culture dc. as above. This species 

 flourishes in rather dry stony places and 

 may be grown in the cracks or fissures of 

 old walls, ruins, or chinks in the rockery. 

 During growth, however, it likes plenty of 

 moisture at the root. 



P. humile. — A pretty Swiss rock plant 

 about 3 in. high, with tufts of linear 

 lance-shaped pointed leaves. Flowers 

 in July, blue, in round heads. 



Culture dc, as above. 



P. limonifolium. — A native of South 

 Europe and Asia Minor, 2-3 ft. high, 

 with smooth lance-shaped slightly toothed 

 leaves. Flowers in June and July, blue, 

 sessile, vsdth conspicuous yellow anthers, 

 and borne on long interrupted spikes. 



Culture do. as above. 



P. Micheli (P. scorzonerifoUum). — 

 A S. European perennial, 1-2 ft. high, 

 with ovate heart-shaped and linear 

 lance-shaped leaves. Flowers in July and 

 August, pale or dark blue, in ovoid spikes. 



Culture do. as above. 



P. orbiculare. — A pretty native spe- 

 cies 6-18 in. high. Lowest leaves lance- 

 shaped cordate, crenate, upper ones ses- 

 sile linear lance-shaped. Flowers in July 

 and August, deep blue, in round heads. 



Culture and Propagation. — This 

 species thrives in chalky gritty soil, and 

 is best raised from seeds sown in cold 

 frames in autumn. 



P. pinnatum. — A native of Crete 3-6 

 ft. high. Lowest leaves ovate acute, 

 upper ones pinnate, with margined and 

 lobed stalks. Flowers in August, blue or 

 white, in loose racemes. 



Culture dc. as above. 



P. Scheuchzeri. — A native of the 

 European Alps, about 1 ft. high. Leaves 

 ovate lance-shaped, bluntly toothed, 

 upper ones linear, nearly entire. Flowers 

 in May, deep blue, in round heads. 



CiMure dc. as above. 



P. Sieberi. — A native of the Apen- 

 nines 3-6 in. high. Lower leaves ovate 

 roundish, somewhat heart-shaped crenate ; 

 upper ones lance-shaped, coarsely toothed, 

 and stem-clasping. 



Culture dc. as above. 



P. spicatuffl. — A British species 1-3 

 ft. high. Lower leaves long-staLked, 

 heart-shaped, ovate acute, twice serrate ; 

 upper ones ovate lance-shaped. Flowers 

 in July, white, creamy, or blue, in long 

 cylindrical spikes. Styles very long; 

 stigmas two. 



Culture dc. as above. Enjoys fully 

 exposed places in the rockery in ordinary 

 good soil. 



CAMPANULA (Bell Flowek).— A 

 genus containing 230 species of beautiful 

 perennial (rarely annual or biennial) 

 herbs varying a good deal in habit, 

 and having the lower leaves usually 

 larger than the upper ones. Flowers in 

 racemes, spikes, or heads, usually blue, 

 violet or white. Calyx tube adnate, 

 hemispherical, turbinate or ovoid, limb 

 deeply 5- cleft or parted. Corolla beU- 

 shaped, rarely funnel-shaped or rotate, 

 more or less 5-cleft. Stamens free. Ovary 

 S-S-celled. Stigma 3-5-lobed. 



Culture and Propagation. — Cam- 

 panulas vary greatly in size, habit, and 

 flower ; but they may all be considered 

 beautiful and worth growing. Most of 

 them are easily cultivated and spread 

 freely in ordinary good soil. The dwarf 

 or alpine species are charming plants for 

 the rock garden, and the larger kinds 

 make beautiful masses of colour in 

 the border. The perennial kinds are 

 easily raised from seed sown in cold 

 frames in spring or autumn, but are 

 more usually increased by dividing the 

 tufts, or by rooting cuttings of the younp; 

 shoots in sprmg under glass protection. 

 Many of the kinds may also be increased 

 by inserting cuttings of the roots about 

 2 in. long in bottom heat in the early 

 spring months. Where the plants are 

 allowed to grow in the flower borders or 

 rockeries without being disturbed for a 

 few years it is advisable to give a good 

 mulching or top dressing of well-decayed 

 manure in autumn or winter. Many of 

 the taller growing kinds will be improved 

 by having a stake placed to them, so that 

 the shoots may be kept from trailing the 

 flowers in the dirt.
