THE CLEMATIS AS A CLIMBER 101 



Undoubtedly the most valuable of the tender Clematises 

 for cultivation under glass are the lovely C. indivisa 

 and its variety lobata. They require the same treat- 

 ment, which comprises a winter temperature with about 

 40 degrees at night, which should not be exceeded. 

 They are best planted out in a thoroughly drained 

 border of loam, peat, and sand, rather rough and with 

 some small lumps left in. Propagation is effected by 

 grafting or by cuttings as in the case of the others. 

 Red spider and scale are among their most trouble- 

 some enemies.
