USDA Plant Hardiness Map

Plants are categorized by geographically-defined areas based on their ability to withstand cold temperatures. These areas are called plant hardiness zones. The USDA established these zones throughout the US according to the average annual minimum temperature.  This information is used by gardeners to determine if a plant is likely to thrive at a location. When purchasing a plant or tree, always check to make sure it is appropriate for the plant hardiness zone where it will be planted. Remember that even if a plant is listed as suitable for a specific zone, it may not survive if the minimum temperature during a particular winter in that zone is unusually cold.
