THE ROSE 245 



The Rosa gymnocarpa, which is indigenous to 

 British America and California, is a pretty and 

 graceful rose, producing fine single flowers that 

 grow in large clusters, and having the element of 

 hardiness that characterizes the wild plant. 



The Chinese rose, in numerous varieties (Rosa 

 chinensis), and the Japanese rose (Rosa rugosa) 

 have made their influence felt in many hybrids. 

 So also has the Wichuriana. The seed pods of 

 the Japanese species are unusually large and 

 handsome. The hybridization of the Japanese 

 rose with the Bon Silene and with other strains, 

 including the Hermosa, produced a number of 

 admirable roses that I have introduced, including 

 the Coquito and Peach Blow. 



The General Jacqueminot, one of the best 

 known of the hardy perpetual bloomers, is itself 

 a hybrid as indeed are all other cultivated roses, 

 no doubt, could we know their precise pedigree. 



It is a hardy and prolific plant, and its quali- 

 ties are curiously prepotent when it is crossed 

 with other varieties. This applies not merely to 

 the form and color of the flower itself but to the 

 entire structure of the plant. Its chief charac- 

 teristics seem to have peculiar prepotency or 

 dominance. But of course the latent character- 

 istics of the variety with which the Jacqueminot 

 is crossed may reappear in later generations.
