Conditional — Some Areas
parsley (zones 5-9) reaches only part of Minnesota (3a-5a): zone 5 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Minnesota spans zones 3a-5a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score parsley against your land's actual soil, sun, and frost.

When to Plant Parsley in Minnesota
The frost window
Across Minnesota, the last spring hard freeze (28°F) clears between Apr 19 and Apr 30, and the first fall hard freeze lands between Oct 10 and Oct 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 163-day window you can count on — up to 181 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 — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — 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.
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 Minnesota's late-side last freeze of Apr 30 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 (USDA PLANTS Database), counting from the last hard freeze it ripens with 88 days to spare even in Minnesota's tightest freeze scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. 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 in part of Minnesota, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Parsley wants 70+ frost-free days; a typical Minnesota site sees ~174 (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 ~1920 GDD (from PRISM 1991-2020 climate normals), so Minnesota'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 Minnesota. 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 Minnesota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Minnesota site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Parsley in Minnesota
Zone compatibility tells you about winter cold survival — but Minnesota growers also need to think about:
Extreme cold (zone 3a: -40F) limits many species
Short growing season (100-140 frost-free days)
Heavy clay soils in the Red River Valley
What to actually do about these — and the constraints that apply to every Minnesota grower, not just parsley — is covered on the Minnesota growing guide.
Timing shifts within Minnesota
Parsley needs about 70 days of frost-free season to complete its cycle. Even Lake County — Minnesota’s shortest season at 137 frost-free days — clears that by 67 days, so season length isn’t the constraint anywhere in Minnesota. What varies is your own parcel.
Across Minnesota’s 87 counties the frost-free season runs from 137 days in Lake County to 199 days in Ramsey County — a spread of 62 days, which is why a single statewide planting date misleads. The median Minnesota county sees 174 frost-free days, leaving parsley about 104 days of slack on a typical parcel — room for a second sowing where the season runs long.
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.
Where in Minnesota Fits Best
Even within Minnesota's zones 3a-5a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for parsley (USDA PHZM 2023):
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 Minnesota's frost window — roughly 174 days, opening after the last 28°F freeze (Apr 19 - Apr 30) and closing at the first (Oct 10 - Oct 17), per NOAA Regional Climate Centers ACIS, 1991-2020.
Minnesota Cooperative Extension
For Minnesota-specific cultivar recommendations, planting calendars, and pest pressure for parsley, the canonical source is University of Minnesota Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Parsley native to Minnesota?
No — the USDA PLANTS Database lists Parsley as introduced rather than native in the Lower 48, so it is not part of Minnesota's native flora. It grows here as a garden plant; pairing it with a few Minnesota natives keeps local pollinators fed too.

Common Questions About Growing Parsley in Minnesota
When can I plant Parsley in Minnesota?
Minnesota's last spring hard freeze (28°F) clears between Apr 19 and Apr 30, and the first fall hard freeze lands between Oct 10 and Oct 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Parsley is frost-tender — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — 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 Minnesota?
Yes — Parsley matures in 75 days (USDA PLANTS Database), and Minnesota's dependable hard-freeze-free window runs 163 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 88 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 Minnesota?
Minnesota spans USDA hardiness zones 3a-5a (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 Minnesota site have?
A typical Minnesota site sees ~174 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 Minnesota?
No — the USDA PLANTS Database lists Parsley as introduced rather than native in the Lower 48, so it is not part of Minnesota's native flora. It grows here as a garden plant; pairing it with a few Minnesota natives keeps local pollinators fed too.
How should I amend the soil for Parsley in Minnesota?
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 Minnesota site — amend for drainage and organic matter first.
