 but as these roses make unsatisfactory growth in this ;s2,eneral

Starting at the non h end of the west I'ow, Rosa mosclmln, 

 R. chinensis \'ar. and R. odorata \'ar. (Tea Rose) are jilanted to 

 illustrate the ancestry ot the Noisette roses. As mentioned pre- 

 viously, this i^roup is not very hardy and thus it is re])i'esented 

 here by only two varieties, Madame Plantier, 1835, and hVUem- 

 berg, 1857. It is doubtful if the last named realK' belongs with 

 the Noisettes. Some authorities ])lace it with the China or 

 Bengal roses. Miss W'illmott gi\-es its i)arentage as R. chinoisis 

 X Diultiflord; this would take it out of the Noisette gi'ou]). 

 Mme. Plantier is one ot the oldest ot the easily obtainable 

 Noisettes. It is co\'ered in June with its ]^ui"e white flowers, but 

 is not remontant, h'ellemberg, on the other hand, ])roduces its 

 bright crimson flowers almost continuously from June to frost. 

 In neither of these \ai'ieties do the llowers ha\'e much "torm," 

 which makes its ajijiearance in this i^rou]) onl\' in those \arieties 

 where the Tea strain pi-edominales.

!'\>llowing the Noisettes is a small grou]) of Bourbon roses. 



The probable oiagin of this group in 1817 (7?. cJiinensis X ddDUi- 



sroia var. h^)ur Seasons) has already been dealt with under 



Climbers (p. 178). Sf) far, we ha\'e been able to obtain only a 



few \'arieties of Boui'bon roses. They are, in the main, weak 



shi'ubs, or pillar roses. Zephirine Drouhin is one ot the best in 



this class. 



China Rosi'.s 



I'\)llowiiig the Bourbons, there is a ])lanling of a icw I'ows of 

 China or Bengal roses. These are ])robabl\' hybrids of Rosa
