316 GARDEN PLANTS. PART II. 



2. L. ramosa. Bears larger flowers, but of not so brilliant a 

 blue ; the variety of this with so-called red, but in reality pale 

 dull, reddish-white flowers, has little beauty to recommend it. 



VALERIANACE.E. 



Centranthus. 



C. macrosiphon RED VALERIAN. A plant about two feet 

 high, with ovate, much-toothed leaves ; bears large, dense heads 

 of small pale-red flowers : a showy annual. Sow in October, 

 and put out the plants in the border when two or three inches 

 high. 



DIPSACE^E. 



Scabiosa. 



S. atropurpurea SCABIOUS DEVIL'S BIT. Bears large, 

 handsome, globose heads of dark-purple blossoms. Sow in 

 October ; the plants will not always flower the same season, but 

 if kept over till the following Cold season will blossom early 

 then. A variety has been produced with scarlet flowers. 



ASTEKACE^E. 



Ageratum. 



A. Mexicanum. An exceedingly handsome plant when in the 

 full height of bloom in the Cold weather, and bearing its num- 

 berless small tassel-like flowers of a very pure, pale-lavender 

 colour. Sow the seed in August, and prick out the young plants 

 into pots, one in each ; in October transfer them to the open 

 ground, only one in one spot, as they are very extensively 

 growing plants. 



Callistephus. 



C. hortensis CHINESE OK GERMAN ASTER. Comprises 

 several distinct varieties, such as Globe ; Hedgehog or 

 Needle ; Bouquet ; and Perfection, with its several varieties, 

 perhaps the most beautiful. These are of nearly every colour, and 

 nothing can surpass in beauty a group of them in full bloom.
