GROUP II. THE DOUBLE YELLOW ROSE. 



This Rose may be distinguished by its flat glaucous leaves, which are usually 

 of a pale or yellowish green. The vigorous shoots grow erect, the weaker ones rather 

 twisted, and both are covered with long thin prickles. 



It is generally allowed to be a native of Persia, first introduced to England 

 from Constantinople. It is notorious for refusing to expand its blossoms, and has 

 been the subject of much discussion. It was apparently unfavourably known in this 

 respect more than two hundred years ago. John Parkinson, who wrote on Gardening 

 early in the seventeenth century, says of it "The flower is so thick and double that 

 very often it breaketh out on one side or another, but few of them abiding whole and 

 fair in our country." As he does not give us any means of remedying the defect 

 we may presume that that was a puzzle to him which still remains so to us. At 

 least, if we can advance a reasonable supposition as to the cause, we have not yet 

 been able to provide a remedy. The methods of treatment and aspects which 

 different writers have recommended to induce this capricious plant to flower con- 

 stantly and well are very various, but all seem of little use. Different aspects have 

 been chosen, and different modes of culture followed, but what has succeeded in the 

 hands of one individual has in like situations and circumstances failed in the hands 

 of another. 



In the first volume of the Gardeners' Chronicle (1841) the Editor invites his 

 correspondents to a discussion on this plant; and, at p. 811, winds up the subject 

 with a leading article. It is there remarked : 



"In what aspect it most flourishes may perhaps be gathered from this, that in 

 ten cases success is connected with an east aspect, in eight with a north, in seven
