Conditional — Some Areas
possum haw viburnum (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 sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score possum haw viburnum against your parcel's actual hardiness, soil, and sun.

When to Plant Possum Haw Viburnum 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.
Winter standing
Minnesota runs as cold as USDA zone 3, and no sourced winter-hardiness floor is on record for possum haw viburnum, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether possum haw viburnum is a permanent planting or a replant-every-spring crop for you turns on your own zone within Minnesota; check its hardiness range against that before treating it as long-lived ground.
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 possum haw viburnum 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
Possum Haw Viburnum wants 120+ frost-free days; a typical Minnesota site sees ~174 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Chill hours
Possum Haw Viburnum requires ~600 chill hours (32-45°F dormancy window). Minnesota typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Possum Haw Viburnum likes near-neutral soil (pH 5-7.5). That's the common-ground band across Minnesota's prairie loam and clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5 and 6.5 — 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.

Possum Haw Viburnum in Minnesota — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 5-9 (USDA PLANTS Database)
- State Zones: 3a-5a (USDA ARS PHZM 2023)
- Growing Season: 28°F hard freezes about Apr 19 - Apr 30 to Oct 10 - Oct 17 (NOAA Regional Climate Centers ACIS, 1991-2020)
What Else to Consider for Possum Haw Viburnum 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 possum haw viburnum — is covered on the Minnesota growing guide.
Timing shifts within Minnesota
Possum Haw Viburnum needs about 120 days of frost-free season to complete its cycle. Even Lake County — Minnesota’s shortest season at 137 frost-free days — clears that by 17 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 possum haw viburnum about 54 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"). Possum Haw Viburnum's 120-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 possum haw viburnum (USDA PHZM 2023):
Pollinator + Wildlife Value
Possum Haw Viburnum 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, possum haw viburnum 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 possum haw viburnum, the canonical source is University of Minnesota Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Possum Haw Viburnum native to Minnesota?
Possum Haw Viburnum is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Minnesota. It can still earn a place in a Minnesota garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Possum Haw Viburnum in Minnesota
When can I plant Possum Haw Viburnum 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). No sourced winter-hardiness floor is on record for Possum Haw Viburnum, so this page does not state whether it overwinters in Minnesota 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 Possum Haw Viburnum grown in across Minnesota?
Minnesota spans USDA hardiness zones 3a-5a (USDA ARS PHZM 2023). Possum Haw Viburnum 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). Possum Haw Viburnum needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Possum Haw Viburnum native to Minnesota?
Possum Haw Viburnum is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Minnesota. It can still earn a place in a Minnesota garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Possum Haw Viburnum in Minnesota?
Possum Haw Viburnum prefers pH 5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Minnesota soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
