USDA Plant Hardiness Zone Map
The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones and further divided into 5-degree F half-zones.
No posters of the USDA Plant Hardiness Zone Map have been printed, but state, regional, and national images of the map can be downloaded and printed in a variety of sizes and resolutions from the Map Downloads page. See the Print Quality Maps page to download high resolution files.
Find Your Plant Hardiness Zone
Enter your zip code in the Quick Zip Code Search box in the map above to quickly see your local plant hardiness zone, or click on the continental United States, Alaska, Hawaii, or Puerto Rico on the map to view the corresponding interactive map. If you have a slower internet connection, you can view national, regional, and state maps as static images by going to the Map Downloads page.
Using the Interactive Plant Hardiness Zone Map
After clicking on the static map above, the interactive map will load. Enter your ZIP code or full address in the search box in the upper left of the interactive map (or click the "your location" control) to zoom to your location. Click on the map at your location of interest to see the plant hardiness zone at that location; you will also have the option to download static maps at different resolutions. In addition to the usual map controls, there is a blue "layers" control symbolized by stacked sheets of paper. This control allows you to turn on or off any of the layers on the map; for example, you may wish to switch off the Plant Hardiness Zone layer when zooming into an exact location in order to orient yourself using the underlying basemap.
