Regions / North America
From the tropical heat of Florida to the arctic cold of Alaska, and from the wide prairies of Nebraska to the deserts of Arizona, the 50 states of the United States vary widely in their climate and topography. They can be categorized into a series of climatically consistent regions. They help identify which shrub, perennial, or tree would survive and grow year after year in each of these regions.
Various initiatives have taken place to determine how well plants would withstand the cold winter temperatures (Plant Hardiness Zones) or when plants would start suffering from the heat (Plant Heat Zones). A more sophisticated approach has been followed by Sunset which defines Climate Zone Maps based not only on hardiness or heat tolerance but also on precipitations, wind, humidity, and various other climate-related factors. These Climate Zones have long been the standard among gardeners who live in the 13 western states.
If you know your hardiness zone, heat zone, or climate zone, find the best plants or exciting garden ideas for your geographic area.
