aDtl is really a fine and vigorous-growing variety. 

 Kosa Fortuniana, a new white Eanksian rose in- 

 troduced from China by Mr. Fortune, in 1850, 

 gives w^hite flowers very double, as large as those 

 of the Noisette Aimee Vibert. They are very 

 fragrant, and the rose is a most desirable variety. 



The Bauksian roses are not adapted for pillar 

 roses, as they are too tender : they require a wall, 

 or very sheltered situation. Their very early 

 flowering, also, renders this quite necessary, as 

 the spring frosts, in cold exposures, destroy the 

 bloom in the bud. They bloom more freely in 

 dry than in wet, retentive soils, and they require 

 pruning with care, for none of the small and 

 twiggy branches should be shortened : but, if the 

 plant has a superabundance, some of them may 

 be removed. If their branches are shortened, 

 they will not bloom, but put forth a profusion of 

 strong shoots. The flowers will be generally 

 found in the greatest abundance on these small 

 and twiggy branches, which at once points out the 

 necessity of their being left on the plant. Often, 

 towards the end of summer, large old plants will 

 produce immensely thick and strong shoots. 

 These should be removed early in autumn, unless 

 they are wanted to fill up a vacancy on the wall ; 

 the upper part of the plant, and its flowering- 

 twigs, will then not be exhausted by them. 



Banksian roses seldom bear seed in this coun- 

 try; but in the south of France and in Italy
