LIST OF FLOWERS 



known for its fragrance; it is not always easily grown, as it requires 

 a calcareous soil and is very susceptible to the ravages of the green- 

 fly. It should be sown in an open, sunny spot, not earlier than the 

 middle of April, in the place where it is intended to flower; it does not 

 like being transplanted. C. macrocephala (Golden Knapweed) is a 

 sturdy plant, attaining a height of 4 feet or more, and its vigorous 

 growth renders it suitable for the flower border edging a shrubbery. 

 There are also other named varieties — Candiiissima, with its beauti- 

 ful silver foliage; Americana, bearing purple thistle-like flowers; 

 and Depressa (King of the Bluebottles), with large rich blue flowers. 

 All can be easily grown from seed. 



CENTAURIDIUM. C. Drummondi is a showy plant with large 

 yellow flowers, growing from 18 inches to 2 feet high. It is often 

 classed as a hardy annual, but is more wisely treated as half-hardy, 

 in which case the seed should be sown in a frame in April and the 

 seedlings planted out in May. 



CENTRANTHUS {Valerian). The Red Valerian (C. ruber) is 

 a sturdy plant bearing bold clusters of dark-red flowers and blooming 

 throughout the summer from June onwards. It is most useful as a 

 covering for steep, stony banks where little else will grow. C. 

 macrosiphon is a hardy annual of less vigorous growth and dwarfer 

 habit, more suitable for the Rock Garden. It may be had with 

 white, rose-coloured and bi-coloured flowers. 



CHEDDAR PINK. See Dianthus. 



CHEIRANTHUS (Wallflower). The Wallflower is so bek)ved 

 of everyone and so well known in gardens of aU sorts and sizes that 

 little need be said as to its culture and its many varieties. It may 

 not be amiss, however, to remark that the seed is often sown too 

 late. May, or even April, if the weather be favourable, is none too 

 early, and enables the plants to attain a sturdy growth, capable of 

 withstanding the assaults of the winter, before being transplanted 

 to their places in autumn in readiness for blooming in the early 

 spring. If the economical practice of saving seed from one's own 

 plants be adopted, the seed should be selected not only from the best 

 bloom but also from the plant of the best form and habit, while it is 

 well to bear in mind that, as its name implies, the Wallflower is not 

 merely a border plant but flowers to perfection in the crevices of 

 old walls — dwarfed, it may be, yet compact and full of blossom.
