ON TREES AND SHRUBS.

5ft. from the ground, it forms a pretty weeping shrub; but when 

 grown on its own roots, it rarely attains more than a few inches 

 high, for which reason it should always find a place in the rock 

 garden. C. p. alhus is a white-flowered form of the last-named, 

 and quite as hardy. C. shipkaensis has clusters of pure white 

 flowers at the apex of the growths, which are very useful for 

 cutting. C. austriaais ( C. bajiaticus) forms a neat bush, 2ft. 

 high, with clusters of yellow flowers from July to September. 



C. Ardoini is fine for the rock garden, as it is of dwarf habit 

 and very free-flowering. C. kewensis {C. Ardoini x C. albus) is 

 quite prostrate or creeping in habit, and bears its cream-white 

 flowers freely ; it is a beautiful rock shrub. C. piirgans is an 

 uncommon garden shrub ; less vigorous in growth than C. prcecox. 

 It is a native of South-West Europe, and although introduced 

 to this country as long ago as 1768, it is even now rarely 

 met with. It is a neat, low-growing species, and in May and 

 June, when laden with its golden-yellow blossoms, is very 

 pretty. 



Daphnes. — The type of the deciduous group, D. Mezereum, is 

 a European shrub of great value in the garden in early spring, 

 and one deserving of more extended culture for its delightfully 

 fragrant reddish-purple flowers, which are produced so abundantly 

 along the whole length of every branch. It loves a cool, moist 

 soil and an open position, but it is by no means averse to 

 partial shade. Beautiful effects are obtained when planted in 

 groups on the grass, using as a carpet such things as Gaultheria 

 prociimbens and Butcher's Broom. There are a few excellent 

 varieties differing from the type in the colour of the flowers and 

 the time of flowering, the principal of which are D. M. fiore-albo 

 (white) and D. M. grajidiflora {autiivinalis) (bright red). The 

 flowers of the last-named sometimes appear in October, and if 

 the winter is mild a display of blossom is kept up until spring. 



D. Genkiva {D. Fortimei) is a beautiful and uncommon 

 Japanese species, with long, slender, gracefully-arching shoots, 

 upon which are borne sweet-scented lilac-coloured blossoms in 

 early spring. This is well adapted for forcing into flower for 

 conservatory decoration during the dull winter months. 

 D. alpifia is a pretty alpine species, suitable for the rock garden, 

 as it rarely exceeds 2ft. in height. It is a close-growing, much- 

 branched shrub, and in ^larch and April produces its small, 

 fragrant, blush-coloured flowers. 



Deutzia.- — Though not large, this genus contains several easily- 

 grown and handsome-flowering shrubs. D. crenata {D. scabj-d) 

 grows in good soil to a height of about 8ft., and when its shoots 

 are laden with racemes of pure white flowers its beauty is 

 evident. The double white flowers of D, c. florepleno are 

 suffused with purple, and borne very freely. D. c. Pride of
