The new 2012 Interactive USDA Plant Hardiness Zone Map
illustrated below is located here.

The 2012 USDA Plant Hardiness Zone Map website includes an interactive-GIS map that
allows the viewer to "click" down in scale to one-half mile. It also includes national, state
and regional images in a variety of resolutions, and a ZIP code finder that provides the
plant hardiness zone for all U.S. ZIP codes.
