This detailed map illustrates the USDA’s updated plant hardiness zones, color-coded by average annual extreme minimum temperature ranges, from Zone 1 (coldest) to Zone 13 (warmest). It includes all 50 states plus U.S. territories such as Hawaii, Guam, Puerto Rico, and the U.S. Virgin Islands, with special notes on Alaska’s zone exceptions like Bethel and Nome. Each zone represents a 10°F difference in average annual minimum temperature, critical for horticultural planning.
