CHAPTER VII. 
DRAPERY FOR TREES AND BUSHES. 
THE numerous hardy climbers which we pos- 
sess are very rarely seen to advantage, owing 
to their being stiffly trained against walls. 
Indeed, the greater number of hardy climbers 
have gone out of cultivation mainly for this 
reason. One of the happiest of all ways of 
using them is that of training them in a free 
manner over trees ; in this way many beautiful 
effects may be secured. Established trees 
have usually exhausted the ground near their 
base, which may, however, afford nutriment 
to a hardy climbing shrub. In some low trees 
the graceful companion may garland their heads; in tall ones 
the. stem only may at first be adorned. But some vigorous 
climbers could in time ascend the tallest trees, and there can be 
nothing more beautiful than a veil of such a one as Clematis 
montana suspended from the branch of a tall tree. A whole 
host of lovely plants may be seen to great advantage in this 
way, apart from the well-known and popular climbing plants. 
There are, for example, many species of Clematis which
