final shape which will be valuable as a reference in all sections of the 

 country, where plants other than tropical are used for landscape effects. 

 The correct selection of plants for various purposes in landscape work 

 is but a part of the success of landscape plantings. One should know 

 not only the correct use of plants as indicated in these lists, but their 

 landscape value from the standpoint of their adaptation to design and 

 composition, as well as how to plant and to maintain them. For those 

 unfamiliar with plant materials the information in this book should be 

 supplemented with additional information which may be easily 

 procured from descriptions in nursery catalogues, encyclopedias, and 

 garden books. 



The Essential Character of the Book. The main idea behind 

 this method of compiling information for the use of those interested in 

 landscape plantings is that of providing a compact reference manual 

 from which fundamental information can be easily obtained. In 

 reality it is more in the form of a "landscape dictionary." The 

 chapters which have been introduced into this volume are a series of 

 summarized fundamental principles with reference to the respective 

 chapter headings, and they are not in the form of many magazine 

 articles, so compiled as to be interesting to many persons who really 

 read the articles, not always because of the facts in them, but because 

 of the camouflaged outlines. 



The System of Nomenclature. In the compilation of the plant 

 lists, and generally throughout the text of the book, an earnest effort 

 has been made to conform to the recommendations of the American 

 Joint Committee on Horticultural Nomenclature as adopted and 

 published in the 1917 official code of standardized plant names. The 

 two new rulings of this committee regarding botanical names also have 

 been adopted. These rulings are that all botanical names except 

 the generic name shall begin with a lower case letter and not with a 

 capital letter; and second, that in the case of all specific names hereto- 

 fore ending in a double "i" one of these "i's" shall be dropped. Thus 

 Berberis Thunbergii will become Berberis ihunbergi. Since this code 

 fails to cover many horticultural varieties of plants it has sometimes 

 seemed wiser to follow the nomenclature of Bailey's Standard Cyclo- 

 pedia of American Horticulture, especially in the case of garden forms 

 of plants. An effort has been made to find the most generally accepted
