established plants until the pots are quite full of roots, and then 

 it is best done directly the buds set. Large plants in borders may 

 be pruned into shape after flowering. Good varieties 



Alba plena, white; Comtessa Lavinia Maggi, white, carmine 

 stripes; C. M. Hovey, crimson; Donckelaari, crimson and white; 

 Lady Hume's Blush, flesh; Marchioness of Exeter, rose. 



Campanula, Bell Flower (campan-ula, from campana, a bell, in 

 reference to the form of the flower. Ord. Campanulaceae) . A large 

 and valuable genus, giving good material alike for greenhouse, 

 border, and rockery. The Canterbury Bell is a Campanula (C. 

 medium), and this, with C. pyramidalis, is best treated as a biennial 

 (see Biennials). Both of these beautiful kinds may be grown in 

 pots. The best of the border Campanulas other than the Canter- 

 bury Bell are as follows: 



carpatica, blue, early summer, 9 ins. high. 



,, alba, white, early summer, 9 ins. high. 



venusta, lavender, early summer, 9 ins. high, 

 glomerata, blue, early summer, 18 ins. high. 



dahurica, blue, early summer, 18 ins. high, 

 latifolia, blue, early summer, 24 ins. high. 



,, macrantha, blue, early summer, 24 ins. high, 

 persicaefolia, blue, early summer, 24 ins. high. 



,, alba plena, double white, 24 ins. high. 



Trachelium, blue, summer, 3 ft. high. 



All of these are readily raised from seed sown out of doors in May, 

 and most of them may be propagated by division in spring. They 

 will thrive in ordinary well-drained soil. Pyramidalis and its white 

 variety should be sown in spring for pot work, pricked off, potted 

 singly in 3 -in., shifted to 6-in., and wintered in a greenhouse. 

 The species fragilis (syn. Barrelieri), with blue flowers in summer; 

 and isophylla, blue, summer, are nice basket plants. The white 

 variety of the latter is even prettier than the blue. For rockwork, 

 carpatica and its varieties; garganica and its variety hirsuta; 

 portenschlagiana (syn. muralis) and the Bavarian variety; Allionii, 

 pulla and the variety G. F. Wilson, pusilla and Rained, may be 

 chosen. See Flower Garden. 



Campion. See Agrostemma, Lychnis, and Flower Garden. 



Canary Creeper, Tropaeolum aduncum or canariense (Ord. 

 Geraniaceae). A pretty yellow-flowered creeper, which comes in 

 useful for verandahs, palings, window-boxes, balconies, and other 

 places. Although a perennial it answers well to treatment as an 

 annual. It is generally raised under glass in March and planted out 

 in May, but if the soil is friable and the position sheltered, it may 

 be sown out of doors at the end of April, and will flower in summer. 



Candytuft. The pretty white, carmine, crimson, and other 

 Candytufts which -we grow as hardy annuals (see Annuals) are the 

 offspring of Iberis coronaria and I. umbellata. The latter is a very 

 old plant, a native of Spain, and bears purple flowers. It is illus- 

 trated in the Botanical Magazine, t. 106. The Candytufts are among 

 the best of the hardy annuals.
