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.
Many of our perennial flowers and herbs are hardy as far north as zones 3 or 4. Cool-season vegetables, most of which tolerate or even like a little frost, will grow well in zones 7 and southward in the fall. This is roughly where we distribute transplants to your local garden center at the proper time for planting. See below to find your gardening zone. Find Your Hardiness Zone by Entering Your Zip Code.
