Gardening enthusiasts across the United States often find themselves navigating through the complexities of climate when choosing plants for their garden. The USDA Plant Hardiness Zone Map provides valuable insight into the average minimum winter temperatures in different regions, helping gardeners determine which plants are most likely to thrive in their specific location.
Zone 1: Extreme Cold
Zone 1, characterized by average low temperatures of -60 to -50 degrees Fahrenheit, represents the coldest zone in the United States. Gardeners in this zone face the challenge of finding plants that can withstand extremely harsh winter conditions.
