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 result is a map that more accurately reflects true plant hardiness and some of the changes are quite interesting. The Plant Hardiness Zone Map divides the United States into numbered zones based on the coldest average yearly winter temperature within that zone. Each numbered zone represents a 10 degree interval, with zone 1 being the coldest zone and zone 13 being the warmest.
