USDA Plant Hardiness Map Updated to 13 Zones
The USDA Plant Hardiness Map has been published since 1960, and has been updated often to account for changes in climate and regional growing conditions. The new version of the growing zones has 26 overall zones, with sub-zones included.
The updated USDA Plant Hardiness Zones map now features 26 zones, which are divided into two sub-zones (A and B) to provide a more detailed picture of the variations in climate within a single zone. The zones range from 1a, with the coldest average minimum temperature of -60°F to -65°F, to 13b, with the warmest average minimum temperature of 30°F to 35°F. The map covers the entire contiguous United States and parts of Canada and Mexico.
The USDA Plant Hardiness Zones map helps gardeners and landscapers make informed decisions about the types of plants that are best suited for their area. For example, plants that are well-adapted to the colder climate of zone 3b, with an average minimum temperature of -45°F to -40°F, are unlikely to survive in the warmer climate of zone 9b, with an average minimum temperature of 25°F to 30°F.
Gardeners and landscapers can use the USDA Plant Hardiness Zones map to choose plants that are appropriate for their climate and provide the right combination of light, moisture, and temperature conditions for successful growth. For example, zone 7a, with an average minimum temperature of 0°F to 5°F, is well-suited to growing plants like blueberries, magnolias, and dogwoods, while zone 11a, with an average minimum temperature of 40°F to 45°F, is ideal for growing tropical plants like bromeliads, hibiscus, and orchids.
The updated map provides a more detailed and accurate picture of the variations in climate across the country and will help gardeners, farmers, and landscapers make informed decisions about the types of plants that are best suited for their area.
