GREENHOUSE FLOWERING PLANTS. 41 



kind of soil and general culture recommended for Pimelea 

 suits them well, except that they have a straggling habit, and 

 require to be trained into conical shape, to show off the flowers 

 to the best advantage. A large specimen, well furnished with 

 healthy foliage and a profusion of flowers, stands high as an 

 exhibition subject. 



PLUMBAGO. 



P. capensis and P. rosea coccinea are the best exhibition 

 plants of this genus. They are easily managed, and being 

 rapid growers, can be trained into a large specimen in a short 

 time. They thrive well in equal parts sandy loam, peat, and 

 well-decayed manure, with a little silver sand. They should 

 be neatly staked, so that the panicles of flower be all placed in 

 the best position to be well seen, and drooping free and grace- 

 fully all over the plant. They should be liberally fed with 

 hquid manure previous to flowering. 



POLYGALA. 



A genus of showy plants of easy culture. The best of the 

 greenhouse species are P. acuminata and P. grandis. They 

 thrive best in a mixture of peat and loam in equal parts and 

 some sharp sand. They should be trained in bush form, as 

 they break freely when the growth is pinched ; and if supplied 

 with liquid manure when growing, they form dense and pro- 

 fusely flowered bushes. 



RHODODENDRON. 



This genus of beautiful flowering shrubs is so well known 

 and highly appreciated that its excellent qualities need not be 

 commented on here. Our remarks are almost entirely restricted 

 to the greenhouse kinds or Indian species. Some of the best 

 and freest flowering, including the new hybrids, are Balsam- 

 inseflorum and its varieties. Album and Aureum, Denisonii,
