The 12 Heat Zones indicate the average number of days each year that a given region experiences "heat days"-those days with temperatures over 86 degrees and the point at which plants experience damage to cellular proteins. The zones range from Zone 1 (with no heat days) to Zone 12 (210 or more heat days). When used in conjunction with the U.S. Department of Agriculture's Plant Hardiness Zone Map, consumers can now select plants that will thrive in their gardens throughout the year.

A full description of the AHS Heat Zone Map and a current temperature gradient map is available.

What do we mean by "southern gardening?"
We mean the region known to gardeners as the Coastal South, stretching from the Gulf coast of Texas to the Atlantic coast of South Carolina. The region as a whole shares a number of distinctive characteristics: long, hot, humid summers; mild winters; abundant rain and sunshine (usually); many native plants; and best of all, the opportunity for year-round gardening.
We focus on North Central Florida because that's where we are, and because it makes a good microcosm of the region as a whole.

Why do southern gardeners need a special website?
Because gardening here is different. We're in the transition zone between temperate and tropical climates. Advice you get from gardening books and instructions on seed packets may give great results in Ohio, but produce only weeds and frustration here. A plant that needs full summer sun in Michigan may look like it's been toasted if it gets full summer sun in Florida. Our mild winters don't kill off bugs and weeds the way northern winters do, and so soil preparation and planting techniques that work up north can yield a bumper crop of aggravation here. In other words, we need a site that tells us how to grow where we're planted.
