The USDA Climate zone map is beneficial in determining the cold hardiness of plants in certain regions. We often refer plants to certain climate zones. To lookup you climate zone, find your region on the map and then find the corresponding color on the chart under the map to see your zone number. The numbers under the color chart indicate the approximate minimum temperatures your area experiences.
