What is the USDA Plant Hardiness Zone Map?
Gardeners use the USDA Plant Hardiness Zone Map to check which plants can grow where. Using your zip code or by looking at a map, you determine what plants can grow outside in your garden.
It can also be used for house plants to indicate where you can grow them outdoors instead of in your home.
