Pennsylvania is not one climate
Pennsylvania’s winter-low ladder runs across 67 counties, from zone 5.5 in Cambria County to zone 7.5 in Philadelphia County. That is 20°F between the two counties’ average coldest night — the difference between canada anemone overwintering in the ground and coming under cover.
The middle half of 67 counties runs 6–7 zones, with a median of 6.5 zones — a 2-zone span end to end.

When to Plant Canada Anemone in Pennsylvania
The frost window
Across Pennsylvania, the last spring hard freeze (28°F) clears between Apr 6 and Apr 24, 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 184-day window you can count on — up to 211 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
Pennsylvania runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for canada anemone, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether canada anemone is a permanent planting or a replant-every-spring crop for you turns on your own zone within Pennsylvania; 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.
Soil + Drainage Fit
Canada Anemone likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Pennsylvania's silt loam and shale-derived — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Pennsylvania site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Canada Anemone in Pennsylvania
Zone compatibility tells you about winter cold survival — but Pennsylvania growers also need to think about:
Rocky shale soils in the ridge-and-valley region
Short mountain seasons in the Poconos and Alleghenies
Deer pressure is among the highest in the US
What to actually do about these — and the constraints that apply to every Pennsylvania grower, not just canada anemone — is covered on the Pennsylvania growing guide.
Where in Pennsylvania Canada Anemone Is Zone-Hardy
Canada Anemone is rated for USDA zones 3–8. Every one of Pennsylvania’s 67 counties sits inside that band — from Cambria County at zone 5b to Philadelphia County at zone 7b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 67 counties Pennsylvania’s winter-low ladder runs from zone 5b in Cambria County to zone 7b in Philadelphia County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Potter County holds its last hard freeze (28°F) until about May 5, while Philadelphia County is clear by Mar 19 — 47 days apart. Set canada anemone out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Canada Anemone’s zone 3–8 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Canada Anemone draws native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, canada anemone can only work that bloom inside Pennsylvania's frost window — roughly 197 days, opening after the last 28°F freeze (Apr 6 - Apr 24) and closing at the first (Oct 25 - Nov 3), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Canada Anemone in Pennsylvania
When can I plant Canada Anemone in Pennsylvania?
Pennsylvania's last spring hard freeze (28°F) clears between Apr 6 and Apr 24, and the first fall hard freeze lands between Oct 25 and Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Canada Anemone, so this page does not state whether it overwinters in Pennsylvania 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 Canada Anemone grown in across Pennsylvania?
Pennsylvania spans USDA hardiness zones 5b-8a (USDA ARS PHZM 2023). Canada Anemone carries a range of zones 3-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Pennsylvania site have?
A typical Pennsylvania site sees ~197 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Canada Anemone should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Canada Anemone native to Pennsylvania?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Canada Anemone as native to Pennsylvania. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Canada Anemone in Pennsylvania?
Canada Anemone prefers pH 5.5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Pennsylvania soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Canada Anemone actually grow on my specific land in Pennsylvania?
