One of the first things that any new gardener should do is identify where he or she lives on the Pennsylvania USDA plant hardiness map. Click on the map above to enlarge it and determine your PA planting zone.
The USDA defines plant hardiness as the ability of a specific species to cope with the average extreme winter low temperatures. To compile the 2023 map, winter temperature information was gathered from thousands of weather stations across the country over a thirty-year period.
Plant hardiness zones were established for all regions of the country by incorporating this information as well as other factors, including elevation and proximity to a significant body of water.
Pennsylvania zones comprise 5a, 5b, 6a, 6b, 7a, 7b, and a very minor portion of 8a. If you are experiencing difficulty locating your location on the mentioned map, you may visit the USDA website and enter your zip code to determine the precise zone in which you are located.
The Pennsylvania planting zones map is an incredibly valuable resource and an excellent starting point for selecting plants. However, local microclimates and specific conditions can influence growing conditions as well.
Many local nurseries will carry plants that are appropriate for your particular gardening region.
