The USDA plant hardiness zone map is the standard by which gardeners can determine which plants are most likely to thrive in a specific location. The way the map works is like this: based on the average annual minimum winter temperature, divided into 10-degree F zones. This USDA zones map will help you determine which zone you’re in, which will in turn help you determine which plants you can grow and when.
