B. TOPIARY WORK AND CLOSE SHEARING. The plants in these two 

 groups (a and b) are selected because they will adapt themselves, with 

 careful attention, to close shearing and interesting topiary work. There 

 are many plants which if sheared closely do not produce any effect of 

 foliage until they have recovered from the pruning. All these speci- 

 mens, however, can be sheared and still retain a mass foliage effect.
