OUTDOOR ROSE GROWING 



To hybridize roses properly one must have a 

 greenhouse and it is astonishing what results may 

 be obtained in a very small one. 



Books on this subject which we have found to 

 be most interesting and practical are: 



"Plant Breeding," L. H. Bailey. 



"Plant Breeding, Experiments of Nillson and 

 Burbank," De Vries. 



"Plant Life and Evolution," Campbell. 



"New Creations in Plant Life," Harwood. 



In Chapter IX will be found a few hints on 

 hybridization taken from our own experiments.
