This tool lets you visualize contemporary and future cold hardiness zones.
The USDA Plant Hardiness Zone Map is used by gardeners and growers to determine which perennial crops and plants are most likely to tolerate winter temperatures. The cold hardiness map is based on the average coldest single overnight temperature of the winter, and is divided into 10-degree F zones.
