ROSE HYBRIDIZATION. 



By Alex. Dickson. 

 {Continued from page ibq.) 



After many years of continuous ex- 

 periment on various lines, we have at 

 last been able to produce what has 

 long been sought for, namely, a yel- 

 low Tea of good size and color with a 

 vigor and hardiness of the Hybrid Per- 

 petual. I refer to the rose Harry 

 Kirk, which is now being grown by 

 most of you, and you will shortly be 

 able to judge whether it fulfills the 

 promises we have made on its behalf. 

 I think you will not be disappointed. 



It is interesting to note, in relation 

 to the La France cross, that the same 

 inclination to sterility is apparent in 

 the rose Augustine Guinnoisseau sport 

 from La France. Out of hundreds of 

 experiments we have not succeeded in 

 getting a single seed pod from this 

 variety. 



The only other point of practical 

 importance, which occurs to me, is the 

 fact that in our early experiments, 

 when we had in view the objeci oi 

 producing varieties which would give 

 a greater continuity of bloom, we used 

 in our efforts Rosa Indica, and, after 

 a considerable amount of labor, we 

 succeeded in impressing this much 

 valued quality on some of its offspring 

 which are now in commerce. 



In a general way we found it very 

 difficult, and indeed impossible to place 

 the smallest dependence upon the pre- 

 sumption that Hybrid Perpetuals would 

 impart to their offspring anything of 

 their own color, and, in a general way 



we may say that after much experience 

 the chief varieties which we use and 

 use with the best results for the pur- 

 pose of gel ting blends are the Hybrid 

 Perpetuals — Horace Vernet, Charles 

 Lefebvre, General Jacqueminot, and 

 also Austrian Briars, Persian Yellow 

 and Harrisonii. 



From what I have said, you will 

 readily appreciate the fact that it 

 would be wholly impossible, and in- 

 deed I think a waste of your time and 

 mine, to give in detail the results of 

 thirty years' hybridising, and I have 

 done my best to make clear the gen- 

 eral lines upon which our work has 

 been conducted, from which it will be 

 readily inferred that the element of 

 chance must always play a prominent 

 part, and I might aptly use the well 

 known quotation from Pope: 



"All nature Is but art, unknown to thee 

 All chance, direction which thou canst 

 not see." 

 And I ask such of you as may de- 

 sire to enter for yourselves upon this 



interesting field of experiment, to go 

 forward with confidence — 

 "Knowing that nature never did betray, 

 The heart that loved her."
