USDA hardiness zone 7b
USDA plant hardiness zone 7b covers areas whose average annual extreme minimum winter temperature is 5 to 10 °F — the standard USDA measure of which perennials survive an average winter. Hardiness zone sets winter survival, but planting DATES depend on your local frost calendar, which varies within a zone. 578 locations on this site fall in zone 7b (Abernathy, TX, Abeytas, NM, Adamsville, TN, Addison, AL, Advance, NC, Afton, VA, Alamo, TN, Albuquerque, NM, and 570 more); open one to see its frost dates, growing-season length, and a printable per-crop planting calendar.

What zone 7b means for your garden
A plant rated "hardy to zone 7b" can be expected to survive a winter whose coldest night lands in the 5 to 10 °F range — the metric the USDA map is built on. That governs perennials, shrubs, and trees. For annual vegetables, what matters is the frost calendar: the dates of the average last spring and first fall freeze, which set when it is safe to plant and how long the season runs. Those come from the individual location pages above.
Zones are from the USDA Plant Hardiness Zone Map 2023, matched to each location's ZIP — see the methodology page. Browse all hardiness zones or crop-by-crop timing.
Frequently asked questions
- What temperature range is USDA zone 7b?
- Zone 7b covers areas whose average annual extreme minimum winter temperature is 5 to 10 °F. Each numbered zone is a 10°F band; the "a" and "b" half-zones split it into 5°F steps.
- Does zone 7b tell me when to plant?
- No — the hardiness zone tells you which perennials survive winter, not when to sow annual vegetables. Planting dates depend on your local last and first frost, which can vary within a single zone. Open one of the sample locations in zone 7b to see its frost calendar and per-crop planting windows.
- What can I grow in zone 7b?
- Almost any common vegetable can be grown in zone 7b; what changes with zone and local climate is the timing and the length of the season. Cold-hardy crops (peas, spinach, lettuce) go out earliest, tender crops (tomatoes, peppers, basil) after the last frost. Use each location's calendar for exact dates.
