  Information about the USDA Plant Hardiness Zone Map
 
 
The United States Department of Agriculture (USDA) is in the process of creating another version of the hardiness map using new mapping technology and an extended set of meteorological data. Questions about the revised USDA hardiness map should be directed to the USDA’s Agricultural Research Service information office in Beltsville, Maryland.
