INTRODUCTION 5 



many larger and more important headings to include the many minor 

 headings. It is here that the reader can easily find reference to lists 

 of plants which are valuable for specific uses by exactly the inverse 

 process that he can find from the Index a reference to the different 

 purposes for which an individual plant may be used. To the reader 

 who is seeking to find a list of plants which can be used for a specific 

 purpose, first, the Table of Contents and the List of Illustrations are of 

 direct and primary value. To the reader who is seeking to find for 

 what specific uses any plant may be adapted, secondly, the Index to 

 pages and groups of plants is of greatest importance. To the reader 

 who wishes to go farther into the subject of plant study, as covered by 

 various phases of landscape work, thirdly, the Bibliography is the one 

 reference which will be of value. The complete glossary containing a 

 complete list of definitions covering terms frequently used by landscape 

 architects is of real value in defining such terms. 



The criticism may be raised by some who consult a volume of this 

 kind that in reality no definite line can be drawn between the uses of 

 some plants for one purpose or for another purpose. This is admittedly 

 a fact. It will be quite evident from a short study of the Index that 

 many plants frequently have a distinct and definite value as adapted to 

 different purposes. 



Range of Material Covered. While the range of material 

 covered by the lists is sufficient to meet the requirements of the average 

 property holder, the lists may be supplemented by additional and 

 unusual varieties which, if selected, should be given unusual care. 

 The information in this book has been compiled to cover the range of 

 material which is adapted for use generally throughout the following 

 portions of the United States: The North Atlantic States, the 

 Great Lakes Region, the Central States as far west as the Missouri 

 River and as far south as Arkansas. No lists have been compiled for 

 the Great Plains and the Rocky Mountain States, but special lists 

 have been compiled for the Atlantic Coastal Plain from Virginia to 

 Mississippi; also for the Peninsula of Florida and for the region within 

 a radius of one hundred and fifty miles from the Twin Cities. For the 

 Pacific Coast, lists have been prepared for the Oregon-Washington 

 Coastal Plain. It should be borne in mind that plants which develop 

 one type of growth in a northern climate will develop another type of 

 growth, because of the longer growing season, in a southern climate.
