FLOWERING SHRUBS 77 



which should be done as soon as flowering is over, send up 

 many strong shoots from the base during the summer ; these 

 will flower their whole length the following season to a height 

 of from 2 ft. to 3 ft. Being perfectly hardy, flowering shrubs 

 of this latter class take up no room under glass when their 

 purpose is accomplished, but they must receive kindly shelter 

 in good time to bring them into bloom before their normal 

 season. 



More than one kind of Cytisus is well adapted for the cold 

 greenhouse, besides the well-known C. racemosus. A beautiful 

 weeping standard may be grown by grafting the Teneriffe 

 broom (C. filipes) upon a laburnum stock, when the drooping 

 branches will be covered with pure white flowers in early 

 spring. This elegant species may also be grown from seed in 

 pyramid form by leading up the main stem and leaving the 

 rest of the branches to themselves. 



Several of the shrubby Spiraeas are popular as pot plants, 

 notably the fine S. Van Houttei, which produces masses of 

 white flowers in early spring under glass. Amongst such 

 smaller-growing shrubs, Deutzia gracilis is an old favourite 

 which we cannot do without, one of the most graceful of 

 any when in flower, blooming well in a 4j-in. pot if desired, 

 and only asking to be cut back immediately after flowering 

 to do better every spring how it would be prized did we not 

 know it so well ! Hybrid forms of these beautiful shrubs are 

 being raised by M. Lemoine of Nancy, who has taken them in 

 hand. One of these, called D. Kalmiseflora from a fancied 

 resemblance, may prove to be an acquisition, as it has flowers 

 of pale pink, edged with a deeper blush. 



Hardy Rhododendrons of the very early flowering section 

 deserve the protection of glass, for in two seasons out of 

 three their flowers are apt to be spoilt by snow and inclement 

 weather. One of the first to bloom is the crimson-flowered 

 R. nobleanum. For planting out in large conservatories, this
