APRIL. 75 



healthy Heaths, and similar plants, are in close contact with 

 the pots, they are rapidly dried up, or heated beyond the 

 degree they are capable of bearing; and in many instances 

 this is the cause of the plants turning what is technically 

 termed " rusty." It proceeds immediately from drought pro- 

 duced by the sun acting so strongly on the exposed pots when 

 placed in the open air, as is a common practice with many of 

 our greenhouse plants. This rusty and naked appearance is 

 also caused by the plants being placed too closely together, 

 thus preventing the free circulation of air, to which we have 

 already alluded. A little attention to these and other points 

 we have adverted to cannot fail to secure success in the art 

 of Heath-culture. 



ROSES. 



The new Bourbon Roses are comparatively few; some of them are, 

 however, first-rate additions to that family. Appoline is one of the 

 prettiest, clear pink, a seedling from Pierre de St. Cyr, on which it 

 is a most decided improvement, being more compact, better-formed, 

 one of the freest late bloomers, and of robust habit ; and as a bou- 

 quet flower it has the approbation of the most distingue marchand 

 in London. Aurora du Guide is violet-tinted crimson, and a good 

 dark flower. Duchesse de Thuringe is, for a small cupped Rose, a 

 perfect model; its colour is light flesh, its habit dwarf, and it is quite 

 a gem in the autumn. Furie is a very free-blooming bright crimson ; 

 but hardly distinct enough from some of a similar colour in this 

 family. Louise Odier is a finely-formed strong- growing variety, a 

 bright rose-colour, and an excellent addition to the pillar varieties. In 

 Menoux we have one of the most brilliant recent additions; it is truly 

 described as " glowing carmine," of dwarf habit, and strikingly beau- 

 tiful. Prince Albert (Paul) is a decided improvement in habit and 

 increased size on Cornice de Seine et Marne : in colour they are 

 very similar, the Prince being somewhat more brilliant. Scipion is 

 a crimson-tinted scarlet, very vivid pleasing colour. Vorace is, how- 

 ever, in my estimation, the gem of the dark novelties of this section ; 

 it is of the most beautiful shape, of large size, and a rich deep vel- 

 vety crimson, and may be described as a perfect flower ; it has also a 

 depth and substance of petal that induces me to believe that it will 

 prove the first fine dark cupped show-ilower (as a single) that has 

 yet been introduced among the perpetuals. 



The most recent additions to the Noisettes are, Caroline Mar- 

 nisse, a counterpart of Felicite Perpetue, now really a perpetual; 

 Narcisse, a delicate pale yellow, not large, but beautifully formed; and 

 Octavie, a novel bright red, of medium size, and an acquisition to 

 this group.
