THE MOCK-ORANGE FAMILY. 44! 



striking successfully. Herbaceous cuttings are made all through 

 the summer, beginning in June or July. Half-ripened shoots 

 are selected for this purpose. The cuttings are stuck into a 

 border of heath-soil, with a northern aspect, or under cloches 

 in small pots or in the open ground, where they soon root. 

 Deutzias and Syringas may also be multiplied from seed sown 

 in spring in heath-soil, which must be kept constantly slightly 

 moist by gentle waterings. The seed, being very small, should 

 be very slightly covered with soil, which explains the necessity 

 for frequent waterings. This mode of propagation, however 

 it may fail to exactly reproduce varieties, is desirable when 

 new varieties are sought for. The seed may be sown in pans 

 or pots, which should be placed under a frame, or in a sheltered 

 place in the open air 



Deutzia. A small genus of Japanese hardy shrubs, repre- 

 sented in our gardens by D. gradlis, D. scabra, D. cretiata, 

 and one or two other varieties. 



There is a very fine and ornamental variety with double 

 flowers, D. crenata flore-pleno (which is described and figured 

 in the 'Revue Horticole' for 1867, p. 70). This variety 

 which, as well as the type, was sent from Japan has very 

 double flowers, of a fine rosy-flesh colour; they are also ex- 

 tremely numerous and handsome. In habit and vigour of 

 growth, the plant exactly resembles the type, except that the 

 bark of the young shoots is somewhat darker in colour. An- 

 other variety, equally fine, is D. candidissima plena, the flowers 

 of which are very double, and of the purest white, without the 

 least tinge of rose. It was raised in 1868 by MM. Froebel & 

 Co., nurserymen, of Zurich, from seed of D. crenata flore-pleno. 

 Although quite as vigorous and free-flowering as the parent, it 

 differs from it very much in habit, which almost exactly re- 

 sembles that of D. Fortunei. Seedling Deutzias bearing double 

 white flowers, shaded or tinged with rosy lilac, have been 

 raised by Mr Willison of Whitby ; and the plants vary 

 much in habit, being, however, mostly very dwarf and free- 

 flowering. 



Philadelphia. These summer-flowering shrubs are so strik- 

 ingly beautiful that one could wish for dwarf-growing free- 

 flowering varieties of them for pot-culture or for forcing in the 

 spring like Deutzias. The following varieties have been raised 

 from seed in French gardens : 



P. Keteleerii. A distinct seminal variety, raised in the Jardin 

 des Plantes by M. Carriere from seed of P coronarius. It 

 has semi-double, white, perfumed flowers (see ' Revue Hort.,' 

 1866, p. 44).
