What the zones mean for Arkansas gardeners

Coldest and warmest towns: among towns with NOAA weather stations, Kingston 2S (2,145 ft) is in zone 7a, while Calion L&d (77 ft) is in zone 8b. That is a difference of about 15°F in the coldest night of a typical winter.
Same zone, different frost dates: within zone 8a, the median last spring frost ranges from March 11 at Des Arc to April 9 at Greenbrier, 29 days apart. Your zone tells you which perennials survive winter; your frost dates tell you when to plant.

Frequently asked questions

What hardiness zone is Arkansas?

Arkansas is in USDA hardiness zones 7a–8b on the 2023 USDA Plant Hardiness Zone Map. Zone 8a is the most common, covering 54% of Arkansas's ZIP codes, and zone 7b covers 22%. Enter your ZIP code for your exact zone.

What does zone 8a mean?

Zone 8a means the average annual extreme minimum temperature, the coldest night of a typical winter, is 10°F to 15°F (−12°C to −9°C). Perennials, shrubs and trees rated for zone 8a or colder should survive winter there.

What is the coldest hardiness zone in Arkansas?

Zone 7a is the coldest zone mapped in Arkansas, found around Kingston 2S, and zone 8b is the warmest, found around Calion L&d.

Did Arkansas'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 8a?

Hardiness zones don't set planting dates; frost dates do. Inside zone 8a in Arkansas, the median last spring frost varies from March 11 to April 9. 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 Arkansas 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.
