How It Works
This tool uses data from the USDA Plant Hardiness Zone Map. The map divides North America into 13 zones based on the average annual minimum winter temperature.
Zone Information
- Zones 1–3: Coldest zones, short growing seasons (80–110 days)
- Zones 4–6: Cool temperate, moderate growing seasons (120–180 days)
- Zones 7–9: Warm temperate, long growing seasons (180–250 days)
- Zones 10–13: Subtropical/tropical, year-round growing
Pro Tip: Use your zone to select plants that will thrive in your climate. Each zone represents a 10°F temperature difference in minimum winter temperatures.
