USDA Zone Finder

The USDA Plant Hardiness Zone Map is a tool for gardeners and growers to determine which perennial plants will most likely thrive in a specific location. The map divides North America into 13 zones based upon the average annual extreme minimum winter temperature, each representing a 10-degree Fahrenheit range. These zones are divided into 5-degree Fahrenheit half-zones, labeled "a" and "b."

The interactive version of the map - located at https://planthardiness.ars.usda.gov/ was created by the USDA Agricultural Research Service to help you find your specific USDA Hardiness Zone. To use, enter your ZIP code to determine your exact zone.

Understanding your hardiness zone is essential for selecting plants that are well-suited to your local climate, thus increasing the chances of growth and survival.
