PLANTS FOR SOUTH ATLANTIC STATES

The territory for which this list has been prepared comprises thatlying between the Atlantic Ocean on the east and the Appalachian foot-hills or Piedmont on the west, and extending from Washington, D. C,to Savannah, Atlanta, and southern Alabama. This territory includesthe eastern half of Virginia and of North Carolina, nearly all of SouthCarolina and of Georgia and all of Alabama lying south and east ofBirmingham (See Plate No. II).

Owing to the influence of the mountains on the west and north,and of the Atlantic Ocean with its Gulf Stream on the east, thisterritory is especially favourable for the growing of plants which wouldnot succeed at the same latitude farther inland. This territory has ahigh annual average humidity and a rainfall of 50 to 60 inches eachyear. It has a low narrow range in temperature—about 30 degrees—and a long growing season, extending from one hundred and eighty daysin the north to two hundred days in the south. All of these factors con-tribute to the successful growth of many somewhat tender plants andin some cases also force the growth of northern plants to a great size.
