USDA Plant and Tree Hardiness Zone Maps by Region
Friday December 26, 2008
Most nurseries suggest planting trees using a specific plant hardiness zone as your guide. U.S. Department of Agriculture's tree and plant hardiness zone map is one good guide in helping you determine a plant’s ability to withstand an average minimum temperature. I refer to plant hardiness zones a lot when reviewing individual trees.
Still, you need to remember other factors, including soil type, moisture, drainage, humidity and exposure to sun and wind can have a direct effect on the success of a plant’s survival. So use a plant and tree hardiness zone map as a guide, but keep these other factors in mind when deciding where and what trees to plant.

I have a HUGE COMPLAINT and don’t know who who get it to that would have enough pull to change the way plants are marketed that we find at our local nurseries. (ie. Home Depot & Lowes). Plants ALWAYS are marked for “Frost Sensitivity” but are NEVER MARKED for “Sun or Heat sensitivity.” What can we do to get this changed! I have lived in AZ for the past 20 years and am tired of replacing plants because not enough info is given.
Get the Sunset Western Garden Book & do your own research. I have noticed things like this plant will take this temerature 15 degrees a big box store and I know it dies at that temperature

I am looking for information on hardiness zones and the trees that live survive in them. Do you know where I can find a database of the different tree species and their hardiness zones?
