What's My Hardiness Zone?

The USDA provides a plant hardiness map based on your average winter low temperatures. Although you often hear it referred to as your growing zone, all it tells you is how cold you get in winter, and helps you select plants that should overwinter well in your area. Your zone tells you very little about your actual growing conditions, simply your plant hardiness requirement.

 

Still unsure? Go to the USDA website and enter your zip code to determine your zone.
