ROADSIDE PLANTING
VIII. Plant Materials
In selecting trees and shrubs for a given location, a survey ol the existing native growth will indicate the species to plant, and the other kinds that can be used. Soil conditions are important and should be carefully studied. A list of suggested material for roadside planting is to be found in this booklet beginning on this page. In this list the scientific names are given as well as the common names, and key letters are included which refer to the regions, outlined on the accompanying United States map, in which the species will grow.
Boundaries of these regions or zones are approximate only and must not be considered as sharp limits of territory in which a given species may thrive. Such divisions can be made only in a general way.
Not all available trees are listed, by any means; many of the soft-wooded species, quick-growing and liable to produce dead wood rapidly are omitted in the interest of more lasting and satisfactory planting.
