State Maps of USDA Hardiness Zones for Planting

USDA Plant Hardiness Zone Map

USDA

One of the most important steps in choosing plants is making sure it is suited to your climate. You can find your USDA zone using these state maps.

These maps are based on the average annual extreme minimum temperatures. They do not account for average maximum temperatures, for example, and some plants may struggle. There is also the possibility of microclimates in your yard that are zones higher or lower than what the maps say they should be.

To read each map, just click on the picture or header to see the full-size map. Click it open until it is as large as possible. Look for the color-coded legend of zones, and match up the correct color and zone to where you live. You can then choose plants that are suggested for that USDA zone.
