United States Department of Agriculture
The United States Department of Agriculture (USDA) created the Plant Hardiness Zone Map to provide guidance to gardeners about which plants are likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.
The map covers the contiguous United States, including Alaska and Hawaii, as well as parts of Canada, Mexico, and Puerto Rico. It includes all of the lower 48 states plus Alaska at a latitude of 60 degrees north. Hawaii and the rest of America’s tropical and subtropical areas are not included because they do not experience routine freezing temperatures.
The map has been through several revisions since it was first created in 1960. The latest version was released in 2012. You can use the map to find your plant hardiness zone and see which plants will grow best in your area.
