USDA Hardiness Zone Map

Use this map to find your USDA Hardiness Zone, a great guide to help you select plants that will thrive in your yard and planting zone.


Know Your Planting Zone

Creating an attractive garden means more than coordinating colors and selecting eye-catching varieties. Aesthetics don't mean much if your gardening zone's weather conditions wilt, freeze, or decay tender plants.

Climate maps or planting zone maps, such as the United States Department of Agriculture Hardiness Zone map, show low-temperature extremes by gardening Zone. Choose plants best adapted to your planting Zone and plant them at the right time to increase your chance of success.

Use climate zone maps as a general guide; many microclimates may exist within a 1-mile radius of your home's gardening zones. Even within your yard's climate zone, variations in exposure and topography can affect plants.

In 2012, the USDA updated the climate zone map with newer data and increased technologies. Using the USDA Web site, you can now access an interactive planting zone map that lets you zoom into an area and view changes in Zones by half-mile increments.
