The Natural Style in Landscape Gardening 



4. Another discovery of still more recent date 

 calls to our aid that branch of botanical science 

 known as ecology. It is readily observed that very 

 few species of plants exist in nature alone. Prac- 

 tically every one associates habitually with certain 

 other species. Thus they form set clubs or societies. 

 And these friendly associations, based upon simi- 

 larity of tastes and complementary habits of 

 growth, should not be broken up. If we as land- 

 scape gardeners desire to preserve the whole aspect 

 of nature, with all its forms intact, we will keep all 

 plants in their proper social groupings. 



For example, if we wish to use the graj;- birch, 

 or squaw birch, to give a good naturalistic dress 

 to some dry hillside, we will not leave it alone, but 

 will use its whole society, the roll of which is some- 

 what as follows: 



SQUAW BIBCH SOCIETY 



Squaw Birch, Gray Birch, Betula populifolia. 

 Dwarf Savin, Dwarf Juniper, Juniperus com- 

 munis. 



Black Huckleberry, Gaylussacia haccata.
