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.
Knowing your 2012 USDA Plant Hardiness Zone is a useful tool when selecting plants for your garden. The zones are based on an area's average annual minimum winter temperature. Use the link above to find out your zone. Then, when you are shopping for plants you should check the zone listed on the plant's tag or label to see if it is suited to your zone. Planting a perennial, shrub or tree whose hardiness zone is Zone 9 in an area that is in Zone 5 means that the plant is likely to freeze and die in winter.
