11. Large Flowered Mock Orange {Philadelphus grandiflora)' Our 

 collection would be very incomplete without an example of the Mock Orange or 

 syringa. There are several species belonging to this genus, which are very 

 beautiful and interesting, especially when in bloom. Grandiflora is one of the 

 best of them. The flowers are large, pure white, and sweet scented, and are 

 produced in great abundance during the month of June. The bush is a vigorous 

 grower ; and if not interfered with will, under favorable conditions, eventually 

 reach a height of 8 or lo feet. Since the flowers are produced only on the 

 wood of the previous year, this may be cut away when the flowering period is 

 over, which v/ill give more room to the new shoots, and they will become better 

 ripened. In this way these shrubs may be kept smaller and made to produce 

 flowers in greater profusion. The syringas will, however, do very well without 

 any pruning beyond the occasional removal of dead wood, and flower freely. 

 The large flowered species is fairly hardy and usually comes through the 

 winter without much injury, especially where partially protected by other trees 

 and shrubs, but in seasons of unusual severity the shoots are often partly winter 

 killed. 



1 2. Large Flowered Hydrangea. Hydrangea paniculata grandiflora. 

 Although placed last, because it is later in flowering, the merits of this hydrangea 

 would fairly entitle it to be put among the first and best of flowering shrubs. 

 It was introduced from Japan in 1874, and during the twenty years which have 

 elapsed, it has become one of the most widely diffused and favorite shrubs in 

 cultivation. It succeeds well under many different climatic conditions, and will 

 grow in almost any soil which is fairly rich, provided it be well supplied with 

 water. Fig. 861 represents a specimen in one of the flower borders at the farm, and 

 shows the profuse flowering habits of this shrub. The clusters of bloom are 

 very large, sometimes nearly a foot long and 8 to 10 inches wide, and are borne 

 at the ends of the branches. After fully expanding, the flowers, which are 

 white, remain in good condition for about a fortnight, after which they begin to 

 assume a pinkish hue and gradually become soiled with dust and by insects, 

 and eventually wither. During the early autumn when this bush is in the height 

 of its glory, there are few other shrubs in bloom. This gives the greater prom- 

 inence to this showy and valuable shrub, which would however hold its place 

 well in any company. This hydrangea is quite hardy in the Ottawa district, 

 and may be propagated by cuttings made from the partly ripened wood during 

 the summer months. — Report Experimental Farms of Canada. 



Bulbs expected to do service a second time must be kept growing as long 

 as possible. The blossoms may be cut, but the foliage must not be injured ; 

 when it turns yellow, withhold water. The bulbs may remain in the soil 

 until wanted. If plump and promising, they may do some service indoors, but 

 if shrivelled or small, throw them away or plant in the open ground.
