22 TREES AND SHRUBS 



BRUCKENTHALIA. A dwarf - growing Ericaceous 

 genus, the seed-pods of which should be removed as 

 soon as the flowers are past, or the plants will be 

 seriously weakened. 



BRYANTHUS. This should be treated the same as 

 the last, which it somewhat resembles. 



BUDDLEIA. Of these, B. japonica, B. intermedia, and 

 B. lindleyana flower on the young wood and require 

 cutting back every winter to within two or three eyes 

 of the old wood ; B. globosa need not be pruned at 

 all, except in a young state to keep it bushy ; and 

 B. paniculala only requires thinning out if it becomes 

 too thick, which is not a very common occurrence. 



CALLUNA (the Ling). This and its numerous 

 varieties should have the old flowers cut off as soon 

 as they are past, and any long or straggling growth 

 cut back at the same time. 



CALOPHACA. The solitary representative of this 

 genus is rather inclined to become straggly if grow- 

 ing at all freely. When this is the case, the plant is 

 benefited by the cutting back of the longer shoots 

 in winter. 



CALYCANTHUS. These require an occasional thin- 

 ning of the branches, and any long shoots may be 

 shortened with advantage. 



CAMELLIA. These, which should be grown out- 

 doors much more than they are, should be cut down 

 if they get unhealthy or unshapely, which should be 

 done in April. Otherwise no pruning is required. 



CARAGANA. Cut away all the straggling or mis- 

 placed branches.
