What is a gardening zone?

A gardening zone is a system used to define the climate of a region and to help gardeners select plants that will thrive in those conditions. The United States Department of Agriculture (USDA) developed the hardiness zone system, which is the most widely used gardening zone system in North America.

The USDA hardiness zone map divides the United States into 13 zones, based on the average annual minimum temperature. Zone 1 is the coldest zone, with an average annual minimum temperature of -50 degrees Fahrenheit or below. Zone 13 is the warmest zone, with an average annual minimum temperature of 70 degrees Fahrenheit or above.

Gardeners can use the USDA hardiness zone map to find out which plants are suitable for their area. Plants are typically labeled with their hardiness zone, so you can easily see if they will be able to survive in your climate.

In addition to the USDA hardiness zone map, there are other gardening zone systems that you can use. The Sunset Western Garden Zone system is designed for gardeners in the western United States, and the AHS Heat Zone system is designed for gardeners in the southern United States.
