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.
Early in 1990 the United States Department of Agriculture (USDA) published an updated version of their map of plant hardiness zones. This divides the United States into 11 zones (1-11), characterised by their average minimum temperature. Zones 2 to 10 are also subdivided into a or b, giving a total of 20 zones or sub-zones. These zones of course only apply to plants growing out of doors with no protection, but which are provided with adequate water.
