 will, as a matter of course, choose among these the 

 one that combines with fragrance the most desired 

 qualities of color and form and size of blossom. 

 DOUBLING THE PETALS AND INCREASING SIZE 



As to the matter of size, it is obvious that not

 tend to produce flowers of exceptional size, and
