Michigan is not one climate
Michigan’s winter-low ladder runs across 83 counties, from zone 4 in Gogebic County to zone 7 in Allegan County. That is 30°F between the two counties’ average coldest night — the difference between jack in the pulpit overwintering in the ground and coming under cover.
The middle half of 83 counties runs 5–6 zones, with a median of 6 zones — a 3-zone span end to end.

Where in Michigan Fits Best
Even within Michigan's zones 4a-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for jack in the pulpit (USDA PHZM 2023):

When to Plant Jack In The Pulpit in Michigan
The frost window
Across Michigan, the last spring hard freeze (28°F) clears between Apr 19 and May 8, and the first fall hard freeze lands between Oct 12 and Oct 31 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 157-day window you can count on — up to 195 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.
Winter standing
Michigan runs as cold as USDA zone 4, and no sourced winter-hardiness floor is on record for jack in the pulpit, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether jack in the pulpit is a permanent planting or a replant-every-spring crop for you turns on your own zone within Michigan; check its hardiness range against that before treating it as long-lived ground.
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 jack in the pulpit survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Jack In The Pulpit wants 175+ frost-free days; a typical Michigan site sees ~186 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a tight window — use transplants and pick early-maturing cultivars.
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
Jack In The Pulpit likes near-neutral soil (pH 4.8-7). That's the common-ground band across Michigan's sandy loam and clay loam — a soil test confirms it for your site.
Plant pH requirements: FAO ECOCROP and USDA PLANTS, with the remaining rows from other published sources or Growable Ground compilation. Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Michigan soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
What Else to Consider for Jack In The Pulpit in Michigan
Zone compatibility tells you about winter cold survival — but Michigan growers also need to think about:
Lake effect weather creates highly localized microclimates
Short northern season (100-120 frost-free days in UP)
Sandy soils in western MI drain too quickly
What to actually do about these — and the constraints that apply to every Michigan grower, not just jack in the pulpit — is covered on the Michigan growing guide.
Timing shifts within Michigan
Jack In The Pulpit needs about 175 days of frost-free season to complete its cycle. 52 of Michigan’s 83 counties give it that outright. The tightest that does is Grand Traverse County at 176 frost-free days — 1 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Michigan’s 83 counties the frost-free season runs from 126 days in Iron County to 223 days in Berrien County — a spread of 97 days, which is why a single statewide planting date misleads. The median Michigan county sees 186 frost-free days, leaving jack in the pulpit about 11 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"). Jack In The Pulpit's 175-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
Jack In The Pulpit draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, jack in the pulpit can only work that bloom inside Michigan's frost window — roughly 186 days, opening after the last 28°F freeze (Apr 19 - May 8) and closing at the first (Oct 12 - Oct 31), per NOAA Regional Climate Centers ACIS, 1991-2020.
Michigan Cooperative Extension
For Michigan-specific cultivar recommendations, planting calendars, and pest pressure for jack in the pulpit, the canonical source is MSU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Jack In The Pulpit native to Michigan?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Jack In The Pulpit as native to Michigan. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Jack In The Pulpit in Michigan
When can I plant Jack In The Pulpit in Michigan?
Michigan's last spring hard freeze (28°F) clears between Apr 19 and May 8, and the first fall hard freeze lands between Oct 12 and Oct 31 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Jack In The Pulpit, so this page does not state whether it overwinters in Michigan and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Jack In The Pulpit grown in across Michigan?
Michigan spans USDA hardiness zones 4a-7a (USDA ARS PHZM 2023). Jack In The Pulpit carries a range of zones 4-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Michigan site have?
A typical Michigan site sees ~186 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Jack In The Pulpit needs 175+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Jack In The Pulpit native to Michigan?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Jack In The Pulpit as native to Michigan. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Jack In The Pulpit in Michigan?
Jack In The Pulpit prefers pH 4.8-7 (USDA PLANTS). That sits in the common-ground band across Michigan soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
