USDA Hardiness Zones provide valuable information regarding the cold hardiness of plants. The United States Department of Agriculture developed these zones to assist gardeners and horticulturalists in selecting plants that are most likely to thrive in specific areas based on their average minimum winter temperatures.

The zones are determined by average extreme minimum temperatures, divided into 10-degree Fahrenheit intervals, ranging from Zone 1, which experiences the coldest temperatures, to Zone 13, which experiences the highest temperatures. Each zone is further divided into ‘a’ and ‘b’ subzones, with ‘a’ being slightly cooler than ‘b’.

These zones indicate the general climate and temperature characteristics of a particular region, allowing gardeners to choose plants that can withstand the cold temperatures of winter without significant damage. By selecting plants within the recommended hardiness zone, gardeners are more likely to ensure the survival and optimal growth of their selected plant species.
