What Are the Planting Zones by State?
The 2023 USDA Plant Hardiness Zones for each U.S. state and territory are listed below with precise Fahrenheit and Celcius temperatures. The updated planting zone map reflects the average annual extreme minimum temperatures from 1991 to 2020. Note: States and territories have multiple hardiness zones; therefore, we use temperature ranges for each.
