Centranthus Ruber : See Valerian. 



Chrysanthemum, Early Flowering : The early-flowering 

 border Chrysanthemums may be treated as hardy perennials, 

 although strictly speaking they are half-hardy. 



Procure rooted cuttings in March, and plant them in a 

 frame, or pot them into pots 3-4 ins. in diameter, in good 

 light loamy soil containing plenty of sharp silver sand. 

 Give plenty of air, and harden off thoroughly, planting them 

 out in good rich soil in April or May. Stake early and 

 give plenty of water during the summer, and about once 

 a fortnight go over the plants and tie them up. They will 

 bloom outside in September and October. In November, 

 when they have been cut down by the frost, lift the roots 

 and store them by planting them close together in a cold 

 frame. In the spring they will start to grow. They may 

 then be split up and planted out in the borders again in 

 April, but to my mind it is better to take cuttings in 

 February, and throw the old plants away in March. The 

 cuttings strike very easily in sandy soil in a cold frame, 

 but must be protected in severe weather. 



Good Varieties. 



Chrysanthemum catalogues are published by many firms 

 during the winter,. The reader is recommended to send 

 for a few lists and make his own choice from these. 



Chrysanthemum, Hardy Perennial : These are quite 

 different from the early-flowering border chrysanthemums
