THE SUMMER ROSE GARDEN. 91 



hide the stem, in a few years forming a pretty dome 

 of foliage and flowers; for covering the naked 

 stems of forest or ornamental trees they are also 

 very useful, as their roots will not injure the tree 

 which supports them ; and if strong copper wire 

 is brought loosely round the trunk of the tree to 

 support their branches, they will give scarcely any 

 trouble in such situations. To make them grow 

 vigorously, give them a supply of manure on the 

 surface, annually in the autumn, to be carried to 

 their roots by the rains of winter. In autumn or 

 winter pruning, their branches must be left their 

 full length, for, if shortened, they will make 

 prodigious long shoots the following season, but 

 produce no flowers ; as they are very flexible, they 

 can be laid in and twisted in any direction, but 

 the use of the knife must be avoided as much as 

 possible. 



THE BOURSAULT ROSE. 

 (ROSA ALPINA.) 



This is a most distinct group of roses, with long, 

 reddish, flexible shoots ; they are not such decided 

 climbers as the preceding three divisions, but they 

 are excellently well adapted for pillar roses : they 

 owe their origin to the Rosa Alpina, a single red 

 rose, a native of the Alps, and also of the hills in 

 the south of France. M. Boursault, formerly a
