The United States Department of Agriculture has recently released an updated version of the Plant Hardiness Zone Map. The color-coded maps can often be found printed on the backs of many seed packets, in many garden magazines and catalogs, as well as on the internet. Gardeners use the maps to determine appropriate growing zones for plants.

See a detailed map of your area at: http://planthardiness.ars.usda.gov/PHZMWeb/
The new version of the map came out of a joint effort of the USDA and Oregon State University, and has much greater detail than the previously used 1990 version.
Press releases by the USDA and other sources indicate that the several zone changes reflect warming temperatures, based on a 30-year study of cumulative weather data (1976-2005). It is important to note that the zone designations represent the average annual extreme low temperatures at a given location during a particular time period. They do not reflect the record coldest it has ever been or ever will be at a specific location, but simply the average lowest winter temperature for the location over a specified time. Low temperature during the winters is usually considered a crucial factor in the survival of plants at a given location.
Compared to the 1990 map, zone boundaries on the new map have shifted by about 5 degrees F throughout much of the nation. The new map includes two new zones in hotter climates: zone 12 (50-60 degrees F) and zone 13 (60-70 degrees F). The higher the zone number, the warmer is the average low temperature during wintertime. Each zone is a 10-degree Fahrenheit band, further divided into A and B 5-degree Fahrenheit zones. The new map also takes into account changes in elevations and closeness to large bodies of water that can influence temperature, something the old map did not address. As a result, there is a slight northward warming trend indicated on the map, but also a few colder areas in mountainous regions. It is significant to note that no geographic location experienced a change of more than one-half zone designation.
The design of the new Plant Hardiness Zone Map is particularly useful on the internet. An interactive version can be found at http://planthardiness.ars.usda.gov/PHZMWeb and allows the user to enter a zip code to obtain the plant hardiness zone for a particular area, or use a drop-down menu to highlight a particular state and its plant hardiness zones. The zones offer important guidelines for all growers, whether they garden small plots, farm large acreages, or grow orchards or forests.
