DESCRIPTION OP THE ROSE. 135 



The best known roses of this family are five in number. 

 The SINGLE AUSTRIAN YELLOW and the SINGLE AUS- 

 TRIAN COPPER may be regarded as the original types of 

 the species. WILLIAM'S DOUBLE YELLOW is an English 

 seedling of a pale-yellow color. HARRISON'S YELLOW is 

 an excellent yellow rose, originated in America. It is 

 very vigorous in growth, and, on the whole, the best yel- 

 low rose for general cultivation. The PERSIAN YELLOW, ' 

 however, is of a much deeper hue, and is unrivalled in its 

 way. It is one of those roses which are feeble on their 

 own roots, but grow very vigorously either on the Dog 

 Rose or on the Manetti stock. It is said to have origi- 

 nated, as its name imports, from Persia. 



A moist soil, and a dry, pure air, are essential to the 

 growth of all this family of roses. 



" No family of roses offers such an interesting field for 

 experiments in raising new varieties from seed as this. 

 First we have the Copper Austrian, from which, although 

 it is one of the oldest roses in our gardens, a double flow- 

 ering variety has never yet been obtained. This rose is 

 always defective in pollen ; and consequently it will not 

 bear seed unless its flowers are fertilized. As it will be 

 interesting to retain the traits of the species, it should be 

 planted with and fertilized by the Double Yellow : it will 

 then, in warm, dry seasons, produce seed, not abundantly ;
