166 BEAUTIFUL FLOWERS 



semi-double; Lady Hume's Blush, flesh; and Reine des Beautds, 

 rose. 



Campanula. Most of the Campanulas are purely flower garden 

 plants, but the blue pyramidal (C pyramidalis) and its white variety, 

 alba, are beautiful plants for greenhouses, conservatories, and lofty, 

 glass-covered porches or corridors. They are hardly suitable for 

 the small, amateur's greenhouse, because they may grow from five 

 to seven feet high. They are raised from seed sown in spring, 

 grown in medium-sized pots until the following spring, and then 

 transferred to large pots. They will flower in summer, and can 

 be discarded after blooming in favour of young plants. 



Canna. The brilliant Canna was referred to under Herbaceous 

 Plants, and its value for the flower garden was pointed out; but 

 we must not forget how useful it is for greenhouses and conserva- 

 tories also. The tubers are potted in the normal soil in spring, 

 and if convenient may be put into a warm house until they are 

 growing freely, and then transferred to the conservatory or green- 

 house, but this is not essential ; it is only advantageous in expe- 

 diting the flowering. After blooming the plants may be gradually 

 dried off, and the tubers stored for the winter. If increase is 

 desired, the tubers may be divided when they start growing in 

 spring. Cannas want an immense quantity of water when in 

 full growth, especially if growing in comparatively small pots; 

 liquid manure will also be of great benefit to them. 



Carnation. See separate section. 



Chrysanthemum. See separate section. 



Cineraria. The Cineraria has been one of the greatest ornaments 

 of greenhouses for many years past, and its popularity only grows 

 with time. Had there been any decline in the favour which they 

 enjoyed when the beautiful florists' varieties reigned supreme, it would 

 have been arrested when the charming Star varieties (see coloured 

 plate) became popularised. They came from an old kind which 

 had been little grown except in botanic gardens, and their graceful
