Kansas is not one climate
Kansas’s winter-low ladder runs across 105 counties, from zone 6 in Atchison County to zone 7 in Wilson County. That is 10°F between the two counties’ average coldest night — the difference between parsley overwintering in the ground and coming under cover.
The middle half of 105 counties runs 6–6.5 zones, with a median of 6.5 zones — a 1-zone span end to end.

When to Plant Parsley in Kansas
The frost window
Across Kansas, the last spring hard freeze (28°F) clears between Apr 1 and Apr 12, and the first fall hard freeze lands between Oct 25 and Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 196-day window you can count on — up to 216 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Frost tenderness
Parsley is frost-tender — FAO ECOCROP puts its killing temperature at 32°F — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does. That is the point where cold damages growing tissue, not a winter-survival floor — an established perennial comes through far colder while dormant, which is what its hardiness zone tells you.
When to start the seed
Those dates are when parsley goes out, not when it starts. It is sown under cover about 7 weeks ahead, so counting back from Kansas's late-side last freeze of Apr 12 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Days to maturity vs. the window
At 75 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 121 days to spare even in Kansas's tightest freeze scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says parsley survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Parsley wants 70+ frost-free days; a typical Kansas site sees ~208 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Parsley needs ~1100 GDD (base 50°F) to ripen. The state median runs ~3821 GDD (from PRISM 1991-2020 climate normals), so Kansas's typical season clears that easily.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Parsley tolerates a wide pH range (pH 5.3-8.3) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Kansas. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6 and 7.5 — worth knowing before you decide whether a Kansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Kansas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Before you plant parsley for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before parsley goes in. What follows is Kansas’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Kansas — and how to grow with it.
We checked the federal record across Kansas — 33,298 documented sites across 8 of the 9 source types we track.
The most significant on record: 146 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Kansas carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Highest-Severity Sites
A note from Gnorman
What an experienced grower watches for around here
In and around Kansas, two things run higher than the national average across Kansas — Nitrate (15,878 sites) and CAFO (485 sites). That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Parsley in Kansas
Zone compatibility tells you about winter cold survival — but Kansas growers also need to think about:
Low rainfall in western KS requires irrigation
Extreme wind and hail during severe storm season
Hot dry summers with 100F+ days
What to actually do about these — and the constraints that apply to every Kansas grower, not just parsley — is covered on the Kansas growing guide.
Timing shifts within Kansas
Parsley needs about 70 days of frost-free season to complete its cycle. Even Greeley County — Kansas’s shortest season at 177 frost-free days — clears that by 107 days, so season length isn’t the constraint anywhere in Kansas. What varies is your own parcel.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Parsley's 70-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Parsley draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, parsley can only work that bloom inside Kansas's frost window — roughly 208 days, opening after the last 28°F freeze (Apr 1 - Apr 12) and closing at the first (Oct 25 - Nov 3), per NOAA Regional Climate Centers ACIS, 1991-2020.
Kansas Cooperative Extension
For Kansas-specific cultivar recommendations, planting calendars, and pest pressure for parsley, the canonical source is K-State Research and Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Parsley native to Kansas?
No — the USDA PLANTS Database lists Parsley as introduced rather than native in the Lower 48, so it is not part of Kansas's native flora. It grows here as a garden plant; pairing it with a few Kansas natives keeps local pollinators fed too.

Common Questions About Growing Parsley in Kansas
When can I plant Parsley in Kansas?
Kansas's last spring hard freeze (28°F) clears between Apr 1 and Apr 12, and the first fall hard freeze lands between Oct 25 and Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020). Parsley is frost-tender — its killing temperature is 32°F (FAO ECOCROP — the point where cold damages growing tissue, not a winter-survival floor) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Parsley mature before first frost in Kansas?
Yes — Parsley matures in 75 days (Growable Ground Plant Database), and Kansas's dependable hard-freeze-free window runs 196 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 121 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Parsley grown in across Kansas?
Kansas spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Parsley carries a range of zones 5-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Kansas site have?
A typical Kansas site sees ~208 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Parsley needs 70+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Parsley native to Kansas?
No — the USDA PLANTS Database lists Parsley as introduced rather than native in the Lower 48, so it is not part of Kansas's native flora. It grows here as a garden plant; pairing it with a few Kansas natives keeps local pollinators fed too.
How should I amend the soil for Parsley in Kansas?
Parsley tolerates pH 5.3-8.3 and well (dry spells) drainage (FAO ECOCROP). That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Kansas site — amend for drainage and organic matter first.
