40 GREENHOUSE FLOWERING PLANTS. 



shoots, when, by giving a short rest to the plants and judi- 

 cious pruning and pinching of the growth, with a little warmth 

 when making wood, fine bushy plants with a profusion of 

 bloom would be the result. N. 0. 7-ubriim and N. 0. album are 

 the two best for exhibition. Unless the plants are wanted for 

 forcing earlier, they should be pruned in March, and started by 

 watering and placing them in mild heat, such as is afforded to 

 a newly started vinery. After the shoots are several inches 

 long, the plants should be taken to the warm end of the 

 greenhouse, and the growth regulated and pinched if neces- 

 sary. When the flower-buds appear, all terminal shoots should 

 be pinched, and the plants regularly watered with weak liquid 

 manure once or twice a week. After flowering, the ripening 

 of the wood and resting of the plants are necessary to future 

 success. 



PIMELEA. 



A genus of shrubby plants, mostly with white flowers, which 

 they produce in great abundance, and are specially attractive 

 as exhibition plants. Two of the best are P. Hendersonii and 

 P. spedabilis rosea. Being natives of New Holland, the soil 

 that suits them best is fibry peat with a little loam, leaf- 

 mould, and sand. When necessary, they should be shifted in 

 early spring, but large plants continue to do well for several 

 years with a top-dressing only. Although they do not force 

 well, they can, by being subjected to a gentle moist heat, be 

 brought into flower earlier than if grown in the greenhouse. 

 They are the better of a little heat to start them, because it 

 gives longer time to ripen their wood in autumn, which is very 

 important for the success of these plants. They are of a bushy 

 habit of growth, and require very little training, except pinch- 

 ing the strong shoots, and regulating the others to get them 

 into proper form. 



PLEROMA. 



A genus of very ornamental shrubs, with showy blue and 

 purple flowers and ovate acuminate-shaped leaves of a shining 

 green colour. The best for exhibition is P. elegans. The same
