USDA Plant Hardiness Zone Map

The Plant Hardiness Zone Map is a breakdown of annual minimum temperature averages that occur in a region over several decades. The maps are periodically updated by the USDA.

One of the features of the hardiness map is the ability to visit the USDA website, type in a specific zip code and see the exact zone hardiness for that area. In fact, West Virginia now has a few spots in the state that are classified as a “Zone 7a.” This means that gardeners can plant new types of flowers or vegetables in those areas. These spots are most prevalent across southern West Virginia counties.
