252 ROCK GARDENS 



from some hanging basket. In the rock garden there can be no 

 more beautiful sight than a good plant of it, when in full bloom, 

 falling over the face of some sunny rock. It is not very hardy, and 

 dislikes excessive damp, so will need a little care in any but very 

 favoured localities. C. isophylla alba is a white, and, if possible, 

 more attractive form. 



C. lanata (syn. velutijia). — Requires the hottest, driest, sunniest 

 crevice to be found. Large woolly leaves. Flower-spikes short, 

 with large, hairy, bell-shaped flowers. Primrose-coloured, and tinged 

 with pink. A lovely and attractive plant, but not easy to keep, as it 

 is very liable to damp off. It should be planted in a vertical fissure 

 and protected from moisture overhead. Flowers in July. Grows 

 readily from seed. 



C. inacrorrhiza. — Likes a vertical fissure in full sun and cal- 

 careous soil. It has a thick, woody root-stock and numerous light, 

 drooping stems, with clusters of fine blue flowers during the winter. 

 A perfectly hardy and easily grown species, and one that should be 

 more frequently used, not only on account of its hardiness, but also 

 because of its blooming in winter. 



C. mollis. — Forms a spreading carpet of glossy leaves about 6 to 8 

 inches high. Flowers dark blue, and freely borne in May and June. 

 Quite hardy, and a useful plant. 



C. niuralis. — Smooth, dark green leaves, forming a carpet some 

 6 inches thick, with deep blue, bell-shaped flowers. Of the hardiest 

 constitution, and one of the best dwarf-growing Campanulas. Some 

 authorities claim this species as being synonymous with Porten- 

 schlagiana^ while others say the latter is a more robust and distinct 

 form. There is also a Campanula in catalogues which rejoices in 

 the name of Porte7ischlagiana Bavarica, which claims to have 

 larger flowers. But, be the name what it may, there is a form of 

 C. muralis of rather taller habit, with larger and deeper-coloured 

 flowers, and if anything miOre floriferous. 



C pulla. — Open, level, sunny spot in peaty soil. Spreads under- 

 ground fairly rapidly, sending up shoots of bright green leaves, and 

 on hairy stems about 3 inches long a solitary, pendulous, bell-shaped 

 flower of the deepest violet-blue in July and August. Of easy 

 culture so long as there is no lime in the soil, which it heartily dis- 

 likes. It is said to die ofl" in an inexplicable manner during 

 the winter, so it is advisable to keep a stock of it in pots to 

 replace casualties. Quite one of the gems of the genus, and in- 

 dispensable. 



C.pulloides. — A chance hybrid, probably between carpatica and 

 pulla. The same parentage as "G^. F. Wilson^'' which its flowers 

 resemble in shape and size, but they have the deep purple of pulla. 

 It is of the same habit, but taller and stronger-growing than pulla.
