What the zones mean for Kansas gardeners

  • Coldest and warmest towns: among towns with NOAA weather stations, Goodland (3,651 ft) is in zone 6a, while Coffeyville Wtr Wks (737 ft) is in zone 7a. That is a difference of about 10°F in the coldest night of a typical winter.
  • Same zone, different frost dates: within zone 6b, the median last spring frost ranges from April 8 at Iola 1 W to April 28 at Ulysses 3NE, 20 days apart. Your zone tells you which perennials survive winter; your frost dates tell you when to plant.

Typical frost dates in each Kansas zone

Medians across NOAA weather stations in each zone. Colder zones usually have later spring frosts, but local terrain can shift the dates by weeks.

Frequently asked questions

What hardiness zone is Kansas?

Kansas is in USDA hardiness zones 6a–7a on the 2023 USDA Plant Hardiness Zone Map. Zone 6b is the most common, covering 54% of Kansas's ZIP codes, and zone 6a covers 24%. Enter your ZIP code for your exact zone.

What does zone 6b mean?

Zone 6b means the average annual extreme minimum temperature, the coldest night of a typical winter, is −5°F to 0°F (−21°C to −18°C). Perennials, shrubs and trees rated for zone 6b or colder should survive winter there.

What is the coldest hardiness zone in Kansas?

Zone 6a is the coldest zone mapped in Kansas, found around Goodland, and zone 7a is the warmest, found around Coffeyville Wtr Wks.

Did Kansas'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 6b?

Hardiness zones don't set planting dates; frost dates do. Inside zone 6b in Kansas, the median last spring frost varies from April 8 to April 28. 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 Kansas 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.
