New Hardiness Zone Maps
by National Gardening Association Editors
But wait, there's more...The National Arbor Day Foundation has released its own hardiness zone map utilizing climate data from more than 5,000 U.S. National Climatic Data Centers during the years 1980-1997. Visitors to the National Arbor Day Foundation Web site can see the new map and also enter their ZIP code to search for their zone. Many parts of the country, especially the Midwest and Central Plains, have been experiencing a warming trend, which is reflected in the Arbor Day Foundation's new map.
