USDA Hardiness Zone Map

The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennial plants are most likely to thrive at a location. The map is based on the average annual extreme minimum winter temperature. The hardiness zone map corresponds with the growing zones and helps indicate when to plant and what plants are suitable for your location.
