Warmer Winters Reshape America's Gardening Landscape

The USDA's updated plant hardiness map reveals that winter temperatures across the United States have warmed by an average of 3.3°F since 1991, expanding growing possibilities for home gardeners. This shift, driven primarily by climate change and enabled by improved weather data collection, signals a fundamental reshaping of agricultural and horticultural practices in the decades ahead. For gardeners, the expanded zones mean access to new perennial varieties, but also underscore the broader climate reality reshaping how we approach food and plant cultivation.
