 The truck gardener specializes on annuals and biennial herbs that 

 accumulate both food and flavors, and to a less extent on peren- 

 nials, like asparagus, strawberries, rhubarb, and berries of various 

 kinds. Floriculture deals with all classes of plants and has for 

 its object the production of attractive flowers and foliage. It 

 reaches its highest development in landscape architecture, in which 

 masses of vegetation are arranged to beautify a landscape with 

 effective arrangements of foliage, and with varied texture and 

 color effects at different seasons of the year. 



Silviculture is the art of growing trees to create forests. The 

 silviculturist specializes on growing trees of many different types 

 for a great variety of uses, such as lumber, pulp wood, bark, 

 rubber, cork, and fuel.
