Vermont is not one climate
Vermont’s winter-low ladder runs across 14 counties, from zone 4.5 in Caledonia County to zone 5.5 in Windsor County. That is 10°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 14 counties runs 4.5–5 zones, with a median of 5 zones — a 1-zone span end to end.

When to Plant Canada Anemone in Vermont
The frost window
Across Vermont, the last spring hard freeze (28°F) clears between Apr 27 and May 5, 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 158-day window you can count on — up to 173 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
Vermont runs as cold as USDA zone 4, 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 Vermont; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Essex County, not the statewide average.
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 Vermont's glacial till and clay — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Vermont site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Vermont's soils run mostly fine sandy loam, but SSURGO maps the series, texture, and drainage under your exact parcel. What matters for canada anemone is the horizon its roots actually work, not the surface. That map unit, not the state average, decides how canada anemone performs.

What Else to Consider for Canada Anemone in Vermont
Zone compatibility tells you about winter cold survival — but Vermont growers also need to think about:
Short growing season (100-130 frost-free days)
Rocky soils throughout the Green Mountains
Heavy clay in the Champlain Valley
Growing canada anemone here specifically
Vermont's soils run mostly fine sandy loam (Spodosols), and whether that suits canada anemone's pH 5.5–7.5 preference comes down to your exact parcel, not the statewide picture.
Pull your parcel's SSURGO map unit, test pH, and amend toward canada anemone's 5.5–7.5 target before planting. How to handle it →
What to actually do about these — and the constraints that apply to every Vermont grower, not just canada anemone — is covered on the Vermont growing guide.
Timing shifts within Vermont
Vermont isn't one climate. In Essex County, the last hard freeze (28°F) holds until about May 13 — roughly 11 days later than the recorded state median — so plant canada anemone to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in Vermont Canada Anemone Is Zone-Hardy
Canada Anemone is rated for USDA zones 3–8. Every one of Vermont’s 14 counties sits inside that band — from Caledonia County at zone 4b to Windsor County at zone 5b — 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 14 counties Vermont’s winter-low ladder runs from zone 4b in Caledonia County to zone 5b in Windsor County — 1 USDA zone of spread, which is 10°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. Essex County holds its last hard freeze (28°F) until about May 13, while Grand Isle County is clear by Apr 20 — 23 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 Vermont's frost window — roughly 163 days, opening after the last 28°F freeze (Apr 27 - May 5) and closing at the first (Oct 10 - Oct 17), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Canada Anemone
Canada Anemone is listed as toxic to dogs, cats (all) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.

Common Questions About Growing Canada Anemone in Vermont
When can I plant Canada Anemone in Vermont?
Vermont's last spring hard freeze (28°F) clears between Apr 27 and May 5, and the first fall hard freeze lands between Oct 10 and Oct 17 (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 Vermont 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 Vermont?
Vermont spans USDA hardiness zones 4a-6a (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 Vermont site have?
A typical Vermont site sees ~163 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. In cooler counties like Essex, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Canada Anemone native to Vermont?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Canada Anemone as native to Vermont. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Canada Anemone in Vermont?
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 Vermont soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
