USDA Plant Hardiness Zone Map - Zone 7

If you want your perennial plants and trees to survive the winter, checking your USDA plant hardiness zone is essential. Average minimum winter temps in Zone 7 are about 0°F to 5°F (Zone 7a) or 5°F to 10°F (Zone 7b). To give your garden and landscape the best chance of surviving the winter, make sure you choose plants that will thrive throughout Zone 7.

Zone 7 Hardiness Temperatures

The USDA determines gardening zones by the average minimum temperature in the winter months. The temps for each zone are separated by a difference of 10°F. For example, the average low temperature of Zone 7 is 10° colder than Zone 8, and the average low temperature in Zone 8 is 10° colder than Zone 9. 

Temperatures for Zone 7a and Zone 7b

Each subzone is separated by 5°F. 

  • Zone 7: The overall zone has a minimum average of temperatures of 0° to 10°F.
  • Zone 7a: This subzone has a minimum average temperature of 0° to 5°F.
  • Zone 7b: This subzone has a minimum average temperature of 5° to 10°F.

Of course, the temperatures don't always stay within this range. Much colder temperatures can occur. The hardiness zones pivot around these minimum average degrees.

No state has just one zone. Most states have multiple hardiness zones because of minor climate differences based on location, landscape, etc. If you're unsure exactly what zone your property is in, the USDA plant hardiness zone map lets you search your ZIP code to find out your hardiness zone.

Our handy chart below shows you which states (and approximately where in the state) are Zone 7a and Zone 7b.

These things are very important to your growing progress. You can find this information in Sunset's The New Western Garden Book.
