USDA Zone Finder
The USDA Plant Hardiness Zone Map is a tool for gardeners and growers to determine the plants most likely to thrive in a specific location.
This map divides North America into zones based on average annual minimum winter temperature, with each zone spanning a 10°F range.
These zones advise which plants will likely survive and thrive in each region. Local microclimates, such as urban areas or areas near bodies of water, may have slightly different conditions than the broader zone classification suggests.
If you visit their official website: https://planthardiness.ars.usda.gov, you can enter your ZIP code, city, or state to find the exact zone.
