Plants suitable for landscape gardening purposes 

 naturally separate themselves into the following broad 

 divisions: Deciduous trees, evergreen trees, deciduous 

 shrubs, evergreen shrubs, perennial or herbaceous 

 plants, and bedding or subtropical plants. There is no 

 intention here of considering the habits, appearance, 

 or methods of propagating these plants. Our subject 

 is landscape gardening, not horticulture, not arboricul- 

 ture or forestry, not soil culture nor grass culture. 

 The principles and art of landscape gardening and its 

 evolution in nature and history are the topics we are 

 studying. 



Evergreens occupy a position and perform functions 

 that count greatly in the general purpose of the lawn. 

 They produce the solid effects, the strong shadows, the 

 enduring colours throughout the season. They shield 

 the smaller, or less rugged plants, trees, or shrubs 

 from the cold winds of winter, especially of March and 

 April. In their alcoves and in the shelters behind their 

 promontories they cherish and preserve alive many 

 shrubs and perennials (flowers) that would otherwise 

 wither under the cold winds and hot suns of early 

 spring. Here again that strange instinct is felt which 

 makes one like to see a great mass of evergreens inter- 

 mingled with hardly any deciduous trees, stretching out 

 in sweeping lines of form and colour, spirey and spread- 

 ing, low or high, spruce, cedar, hemlock, pine, or juniper, 

 blue, silver, green and fiery red, crimson and dainty 

 pink, June and November, ever changing, boldly 

 flaunting, or softly melting into delicate tender hues.
