PERNETIANA.— Prawe in March. 



This new race of Roses was first obtained by 

 crossing Soleil d'Or with a H.T., and are really hybrids 

 of Austrian Briar (Rosa lutea) ; but the Council of the 

 National Rose Society have decided that they must now 

 be separately classified, and have given them the name 

 of Pernetiana (R. Pernetiana). They require the same 

 pruning treatment as the Hybrid Teas, but as their 

 growths are somewhat pithy and very liable to be damaged 

 by frost, care must be taken when pruning to see that 

 the cut is made well below the damaged part. 



INSTRUCTION 21. 



SCOTCH BRIARS.— Prune in March. 



The Scotch Briars may be left about 3 -ft. high or a 

 little higher. The young suckers, which are freely pro- 

 duced, may be cut shorter, so as to clothe the base. 

 Remove only the old worn out and weak wood ; in fact, 

 hardly any pruning at all is required.
