USDA Plant Hardiness Zone Map adjusted to Account for Warming

Jan 26, 2012; 1:07 PM ET

The USDA has released an updated version of their plant hardiness zone map for the first time in 22 years. The map accounts for recent warming trends and thus some zones have been adjusted northward.

The new map, located on the USDA website, uses 30 years of weather data gathered from 1976 to 2005 and is more precise than the 1990 version, showing smaller areas and accounting for higher elevations and bodies of water that can influence temperature, according to the USA TODAY article

The nice thing about this interactive map is that you can click on your region and see the zone breakdown in just one-half mile segments!

No section of the country changed more than half a zone, according to the USDA.
