Choosing the right flowers, shrubs, trees, and herbs to thrive in your yard or garden can be difficult. However, one of the best ways to ensure that plants are happy and healthy is to start with plants suited to your USDA hardiness zone or average temperature.

USDA plant hardiness zone maps are based on extreme minimum and typical high temperatures. However, it's important to note that they do not account for extreme maximum temperatures, like unexpected heat waves, so some plants may still struggle.

The USDA (United States Department of Agriculture) revised the map in 2023 to account for a warming shift. The 2023 map is about 2.5 degrees warmer across the continental U.S. than the former 2012 maps. The USDA has kept records for decades, publishing the first growing zone map in 1960.

Here's a list of 54 USDA hardiness growing zone maps for the U.S. and a selection of territories and districts. To read each map, click on the picture or header to see the full-size map. Look for the color-coded legend of zones, and match up the correct color and zone to where you live. Choose plants to grow based on the USDA zone.

Tip

When sowing seeds or purchasing plants from a nursery, refer to the care instructions about the hardiness zones. Some plants can survive low-temperature zones if brought indoors for the winter.
