If you are not sure what growing area you are in, you can enter your zip code in the tool at the top right of the website and it will tell you. Gardeners need a way to compare the climate in their garden to the climate in which a plant is known to grow well. The USDA created a standard that gardeners can use to determine which plants can survive in which locations. However, some of the changes in zones are the result of new and more sophisticated methods for mapping zones between weather stations.

Not all endurance maps, such as the Arbor Day map, list the 13 zones and may not include breakdowns “a” and “b”, but they have a relatively similar design. Now that you have used this page to find your hardiness zone, when you are buying plants, check the plant label and a zone range will almost always appear in the list. Based on ten-year minimum average winter temperatures, maps of plant hardiness zones have been progressively developed, first by the Department of Agriculture (USDA) for the United States and then applied more or less to the rest of the planet. For example, if you're in zone 6, plants that are in zone 5-8 will survive your winters well.

To take a closer look at the different regions, the USDA offers an interactive tool that allows users to view a compilation of hardiness zones in one of the five general regions of the contiguous states.

The USDA map is the map trusted by most gardeners in the eastern United States, and the one currently used by most national garden magazines, catalogs, books, websites, and nurseries. If you see a hardiness zone in a garden catalog or in a plant description, you're likely referring to this USDA map.

To help develop the new map, the USDA and OSU requested that horticulture and climate experts review the areas of their geographical area, and the test versions of the new map were revised based on their expert feedback. If you know your hardiness zone, find the best plants or interesting garden ideas for your geographical area. Hardiness zone maps are essential to helping gardeners choose plants, but they are not all-inclusive categories.
