In addition, C. pyramidalis is a biennial species largely grown for 

 greenhouse decoration. It grows 4-6 ft. high, and has white and blue 

 forms. The seeds are sown one year to produce plants for flowering the 

 next They realize from 8s. to 10s. per 100 in the young stage. 



Candytuft (Iberis). Although there are several species of Iberis the 

 one most popular is /. umbellata, a pretty South European annual 6-12 in. 

 high, having purple umbels of blossom. There are several varieties, such 

 as atropurpurea, deep crimson; carnea, flesh; and dwarf forms also of 

 various shades. They are all easily raised from seeds sown in gentle heat 

 in spring, the young plants being sold in clumps or in shallow boxes for 

 bedding out Other annual Candytufts are /. violacea, 3 in. high, purple; 

 /. coronaria, pure white, with some fine forms; /. Bemardiana, 6 in., pink;

Canterbury Bells (Campanula Medium). Everybody knows and 

 admires the Canterbury Bell, which is an imposing hardy herbaceous 

 biennial of pyramidal habit of growth and profuse flowering. The "cup 

 and saucer" section of these flowers is perhaps the more attractive and is 

 distinguished by the varietal name of Calycanthema. The shades of colour 

 in both sets include white, blue, mauve, pink, &c., and there are also double- 

 and single-flowered varieties, all of which may be raised from seeds sown 

 during the spring months either in frames or in the open. It should be 

 stated that, however carefully the seeds are harvested or grown, a certain 

 percentage will not be true to their kind, whether of single or double 

 varieties. 



The plants grow with considerable freedom in any good garden soil, 

 and where cultivated by the acre as a root crop are productive of a good
