TREES AND SHRUBS FOR SEASIDE PLANTING 189 



types which make excellent specimens and good mass plantings. 

 The location considered in this discussion is along the northeast shore, 

 where the exposure is the most severe. In the inland sections, removed 

 from the severe exposure of the salt water, and protected by buildings 

 and woodland developments, a large part of the list of generally hardy 

 shrubs used throughout New England can be planted with safety. 

 All of the material in this group, however, has been under observation 

 for a number of years and has proven itself thoroughly hardy. 



In going farther south along the less-exposed New England shores 

 we find a group of trees and shrubs which are fully hardy, but which 

 do not develop at their best along the severe exposures of the Maine 

 Coast. All of the material shown in the first list is fully hardy along 

 the New England Coast and the less-exposed shore locations. There 

 are many other shrubs which might prove hardy. Under the author's 

 observation many types of this material have been used at one time or 

 another. Sources of responsible information have been further con- 

 sulted and many plants of questionable hardiness, which might otherwise 

 have been included in these groups, have been for the present omitted. 



LIST OF TREES AND SHRUBS FOR SEASIDE PLANTING 



A. Plants Hardy Under the Severe Exposure of the North 

 Atlantic Coast. Our only safe guide in the selection of plant types 

 for the extreme exposures along the northeast coast is the experience of 

 those who have endeavoured to acclimate a wide range of plant 

 materials. These plants have proved thoroughly hardy, but it is 

 possible that other plants which may be tested out in other locations 

 or in the future will prove equally as hardy.
