CULTIVATION 



27 



Climbers are always most effective when their stems are 

 allowed to grow with a certain amount of freedom. A 

 tangle of shoots is natural, and if they are flowering plants 

 their flowers produce a more pleasing effect than when 

 strict training is practised. 



A list of climbing plants for cultivation in greenhouses, 

 corridors and conservatories, limited strictly to plants of 

 climbing habit, would exclude a number of shrubs which 

 are grown as climbers. It has already been pointed out 

 that it is difficult to draw the line between shrubs that 

 are climbers and those that are not, and for our pur- 

 pose it is not necessary to draw it. The following plants 

 are known to be suitable for the purposes named. It is 

 only necessary to mention the genera here. The alpha- 

 betical list under Chapter XIV should be consulted as to 

 species :
