USDA Plant Hardiness Zones 1–13
Each zone is defined by the average annual extreme minimum winter temperature (10 °F bands).
| Zone | Extreme min. temp | Typical last frost | Typical first frost |
|---|---|---|---|
| Zone 1 | −60 to −55 °F | mid Jun | late Aug |
| Zone 2 | −50 to −40 °F | late May – mid Jun | early Sep |
| Zone 3 | −40 to −30 °F | mid May – early Jun | mid Sep |
| Zone 4 | −30 to −20 °F | early – mid May | late Sep |
| Zone 5 | −20 to −10 °F | mid – late Apr | mid Oct |
| Zone 6 | −10 to 0 °F | early – mid Apr | late Oct |
| Zone 7 | 0 to 10 °F | mid – late Mar | early Nov |
| Zone 8 | 10 to 20 °F | early – mid Mar | mid Nov |
| Zone 9 | 20 to 30 °F | mid Feb – early Mar | early Dec |
| Zone 10 | 30 to 40 °F | mid Jan – early Feb | rare / mid Dec |
| Zone 11 | 40 to 50 °F | frost-free most years | frost-free |
| Zone 12 | 50 to 60 °F | frost-free | frost-free |
| Zone 13 | above 60 °F | frost-free | frost-free |
Data source: Zone ranges follow the USDA Plant Hardiness Zone Map (USDA 1–13 scale). Frost windows are typical general-guidance ranges — actual dates vary by microclimate and from year to year. Frost-free zones (11–13) are tropical; zones 1–2 have a short season and rely heavily on fast-maturing cool-season crops.
How to use your zone
- Your zone tells you which perennials survive winter where you live, and roughly when spring sowing can start.
- Zones are set by winter cold, not summer heat — two gardens in the same zone can still have different summers.
- Microclimates (sheltered courtyards, south-facing walls) can run one zone warmer than the map says.
- Once you know your zone, use the planting calendar by zone for crop-by-crop windows.
Note: this site uses the US USDA hardiness scale only. If you garden outside the United States, zone numbers from other national systems do not map one-to-one — check your local meteorological service for equivalent guidance.
