Plant Hardiness Zone Map

The 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.

The site 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.
