Massachusetts USDA Plant Hardiness Map
The USDA released a plant hardiness map for 2023 that reflects average winter low temperatures over the last 30 years.
The map has changed somewhat from previous versions to take into account the general winter warming trend across the country.
The Massachusetts planting map includes zones 5a, 6a, 6b, 7a and 7b. To see a closer image of the zones, you can click on the map above. Once you find your location on the map, you can use this information to find the best plants suited for your Massachusetts zone.
It is important to note that the USDA plant hardiness map is useful as a foundational tool when choosing plants. Other factors do affect the vitality of plants in a certain area. These factors include, wind, soil, humidity, winter sunlight, pollution and how you plant and care for plants.
The USDA plant hardiness map is used by most nurseries and is noted on the plant label. If you do not see the hardiness zones indicated, be sure to ask someone at the nursery who can provide that information for you.
Most local nurseries will sell only plants that will survive in the area in which they are located.
