What are Plant Zones?
Plant zones, also known as hardiness zones, are geographically defined areas that are determined by the average annual minimum winter temperature. The United States Department of Agriculture (USDA) has developed a Plant Hardiness Zone Map, which divides the country into different zones based on temperature ranges. This map helps gardeners and landscapers choose plants that are most likely to thrive in their specific climate.
