gives satisfactory results under his particular condi- 

 tions, he should be slow to discard it in favour of any 

 other variety, however desirable, which has been in- 

 cluded. 



No Rose has been included in the general list 

 which has not been grown by some member of the 

 Committee, but information as to the- newer Roses is 

 of necessity imperfect, and judgment as to these must 

 be considered provisional. 



Roses of 1920 which appear promising have been 

 included in a Special List, iDUt the Committee do not 

 profess to pass any final opinion upon them. 



The section as to pruning has been revised in the 

 light of the further experience gained since the publi- 

 cation of the last edition. The descriptions appearing 

 in the Select List from pages 29 to 71 end with 

 a reference to a figure, e.g., " Anna Olivier — prune 

 4 or 5," and this indication is intended to refer to the 

 relative number of the instruction contained in the 

 pruning section on pages 83 to 121. 



In the case of some of the more vigorous dwarf 

 Roses these pruning instructions may, under suitable 

 circumstances, be wholly or partially disregarded. 

 Where ample space can be allowed', and under con- 

 genial conditions, many of these Roses will grow 

 naturally into large bushes, and under such conditions 

 they will thrive best with very little pruning beyond 

 the removal of old wood, and will produce in their 

 season a wealth of bloom which cannot be equalled 

 by plants of the same variety which have been pruned 

 in the more orthodox fashion.
