develop. Though they may be had in flower early, 

 they are much appreciated in the greenhouse, even 

 as late as the month of May. The larger growing 

 D. crenatctj with its numerous varieties, Candidissima 

 Jlore-pleno, Wellsii, and Watererii will not bear hard 

 forcing, but can be had in flower with little trouble 

 in April and May. Good, well-ripened bushes may 

 be lifted in the autumn, and if potted and carefully 

 attended to they will flower well the following 

 spring. 



DIERVILLA (WEIGELA). Many of the Bush Honey- 

 suckles, as the Weigelas are called, will flower well in 

 a cool house, but they do not last sufficiently long in 

 bloom to make them of great value for this purpose. 

 The best is the dark-coloured Eva Rathke, which grows 

 naturally into a neat bush ; the flowers are of claret 

 colouring. 



HEATHS. Erica carnea is very pretty in a cool house 

 in midwinter, all that is needed being to lift the 

 clumps from the open ground, pot, and keep watered ; 

 while the large-growing Portuguese Heath, E. lusi- 

 tanica, which flowers naturally in February in the 

 open ground, when the weather is not too severe, 

 well repays glass protection at that season. 



FORSYTHIA. The Forsythias flower in the open 

 ground by the month of March, and indoors, of 

 course, much earlier. The most effective is F. 

 suspensa, which is naturally a climber, or, at all 

 events, of loose and rambling growth. When needed 

 for pots, tie the principal shoots to a stout stake, and 

 let the smaller branches grow at will, the result being
