A '''plant hardiness zone''' is a geographical area defined by the ability of [[plants]] to survive the [[winter]] in that zone.  The [[United States Department of Agriculture]] defines plant hardiness zones by average annual extreme minimum [[temperature]] and revises these zones periodically, most recently in 2012, to account for temperature changes.<ref>[http://planthardiness.ars.usda.gov/PHZMWeb/ USDA Plant Hardiness Zone Map]</ref><ref>[http://planthardiness.ars.usda.gov/PHZMWeb/AboutWhatsNew.aspx What's New]</ref>  A [[gardening|gardener]] can use the zones to tell which plants will survive the winter in his area.  For example, if a plant is listed as hardy from zones 3-8, a gardener in a zone below 3 or above 8 will know that the plant will survive with difficulty, if at all.<ref>[http://www.dutchbulbs.com/resources/hardinesszones Hardiness Zones]</ref>
