The planting zones, also called hardiness zones, divide the United States, Mexico and Canada into 11 areas. Each of the gardening zones is based on a 10 degree Fahrenheit difference in the average annual minimum temperature. Planting Zones 1 and 2a, the coldest, represent Canada. The United States falls within zones 2 through 10. Hawaii and Mexico are represented by zone 11, the hottest zone.
The USDA created a Plant Hardiness Zone Map in 1990 that divides the country into 11 zones, each separated by approximately 10 degrees in temperature. To further complicate things, some zones (like mine in Alabama) are further broken down into a and b zones.
