revised hardiness zone maps
For the first time in over twenty years, the USDA has revised the USDA Plant Hardiness Zone Map that reflects that average annual lowest temperature across the country, enabling gardeners to determine what perennials to plant in their respective regions. The new maps generally reflect a five degree warmer temperature change than the previous map.
Check out the USDA’s website to find out your hardiness zone because the website enables you to drill down to your specific zip code to find your zone. Make sure to remember your zone for all of that spring garden shopping coming up!
