DOUBLE-FLOWERING VARIETIES.

BEGONIA GLOW. Double Pelargonium type. (See p. 59.) 



The plants of double-flowering varieties are, however, as a rule not possessed 

 of so much vigour as the singles, requiring an extreme amount of care, 

 cleanliness, and high cultivation to bring them to perfection ; but there is 

 hardly a plant in the whole range of horticulture that will so well repay 

 care and petting as this. The foliage of the double forms is smaller and 

 the stems are finer, almost invariably; but as they are also firmer or more 

 "twiggy" in character, propagation by means of cuttings is rendered much 

 more easy than in the case of the singles. 



POTTING AND COMPOST, ETC. 



THE tubers are started in exactly the same manner as directed for singles 

 on p. 48, but as the roots of double kinds are finer and more fibrous, the 

 soil should not perhaps be of quite so rough a description, though it must 

 be thoroughly porous, and the plants should be potted somewhat more firmly,
