What Hardiness Zone Is Texas?

Q: What hardiness zone is Texas?

Texas is in USDA hardiness zones 6b–10b on the 2023 USDA Plant Hardiness Zone Map. Zone 8b is the most common, covering 38% of Texas's ZIP codes, and zone 9a covers 22%. Enter your ZIP code for your exact zone.

Q: What does zone 8b mean?

Zone 8b means the average annual extreme minimum temperature, the coldest night of a typical winter, is 15°F to 20°F (−9°C to −7°C). Perennials, shrubs and trees rated for zone 8b or colder should survive winter there.

Q: What is the coldest hardiness zone in Texas?

Zone 6b is the coldest zone mapped in Texas, found around Dalhart, and zone 10b is the warmest.

Q: Did Texas's hardiness zones change in 2023?

The USDA released a new Plant Hardiness Zone Map in November 2023, based on 1991–2020 temperatures instead of 1976–2005. About half of the United States shifted half a zone warmer. Check your ZIP code here, because plant tags and older books may still list your 2012 zone.

Q: When should I plant in zone 8b?

Hardiness zones don't set planting dates; frost dates do. Inside zone 8b in Texas, the median last spring frost varies from February 27 to April 5. Look up your local frost dates and plant tender crops such as tomatoes after the 10%-risk last-frost date.

What the zones mean for Texas gardeners

Coldest and warmest towns: among towns with NOAA weather stations, Dalhart (3,984 ft) is in zone 6b, while Galveston Scholes Field (5 ft) is in zone 10a. That is a difference of about 35°F in the coldest night of a typical winter.
Same zone, different frost dates: within zone 8b, the median last spring frost ranges from February 27 at Langtry to April 5 at Prade Rch, 37 days apart. Your zone tells you which perennials survive winter; your frost dates tell you when to plant.

Zone 6b is the coldest zone mapped in Texas, found around Dalhart, and zone 10b is the warmest.

Did Texas's hardiness zones change in 2023?

The USDA released a new Plant Hardiness Zone Map in November 2023, based on 1991–2020 temperatures instead of 1976–2005. About half of the United States shifted half a zone warmer. Check your ZIP code here, because plant tags and older books may still list your 2012 zone.

When should I plant in zone 8b?

Hardiness zones don't set planting dates; frost dates do. Inside zone 8b in Texas, the median last spring frost varies from February 27 to April 5. Look up your local frost dates and plant tender crops such as tomatoes after the 10%-risk last-frost date.

Zone and frost dates: use both

Your hardiness zone answers one question: will this plant survive the winter here? Choose perennials, shrubs, trees and bulbs rated for your zone or a colder one. For vegetables and annuals, what matters is the length of the frost-free season. See Texas frost dates by town, or get a planting calendar for your ZIP code with start-indoors, transplant and sowing dates for 30 crops.

Sources and method

Zones are from the USDA 2023 Plant Hardiness Zone Map ZIP-code files published by the PRISM Climate Group, Oregon State University, based on 1991–2020 minimum temperatures. ZIP codes are assigned to states by USPS prefix. Town zones use the ZIP code nearest each NOAA 1991–2020 Climate Normals station. This is an independent tool, not an official USDA site.
