2012 USDA Hardiness Zone Map

The 2012 USDA Plant Hardiness Zone Map helps gardeners and growers determine which plants are most likely to thrive at a location. For the first time, the map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended. Users may also simply type in a ZIP Code and find the hardiness zone for that area.
