 and then must not be removed at once, but at

 varieties, with large flowers and more beautiful 

 foliage. This is one of the prettiest climbing 

 roses known. A friend informs me that some 

 pillars of this rose at Geneva are thirty feet 

 liigh, and covered with flowers the greater part of

 variety, but still interesting and pretty. Large

 pruning, or to the winter killing the small 

 spray-like shoots from which they are generally 

 produced. 



These roses have but few adaptations. I have 

 given under Grrevillia Rose their culture as pillar 

 roses. For these and for warm situations against 

 walls they are very ornamental : they also bloom
