Unlikely — Zone Mismatch
Pacific madrone (zones 9-13) does not overlap with West Virginia's zone range (5b-7a). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Pacific Madrone is hardy to zone 9, and the warmest ground in West Virginia is zone 7 — 2 zones short. Planted in open ground it will not survive a West Virginia winter. To grow it here, grow pacific madrone in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

West Virginia is not one climate
West Virginia’s winter-low ladder runs across 55 counties, from zone 6 in Hardy County to zone 7 in Wyoming County. That is 10°F between the two counties’ average coldest night — the difference between pacific madrone overwintering in the ground and coming under cover.
The middle half of 55 counties runs 6.5–7 zones, with a median of 6.5 zones — a 1-zone span end to end.
Measured across 55 West Virginia counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Pacific Madrone Stands in West Virginia
Pacific Madrone is rated for zones 9–13 — a cold floor USDA puts at 20 to 30°F. No West Virginia county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about West Virginia winters, not about pacific madrone.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Pacific Madrone in West Virginia
The frost window
Across West Virginia, the last spring hard freeze (28°F) clears between Apr 4 and Apr 15, and the first fall hard freeze lands between Oct 26 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 194-day window you can count on — up to 215 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
West Virginia runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for pacific madrone, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pacific madrone is a permanent planting or a replant-every-spring crop for you turns on your own zone within West Virginia; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Pocahontas 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.
Growing Season Fit
The zone check says pacific madrone does not survive a West Virginia winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on West Virginia under protection.
Chill hours
Pacific Madrone requires ~200 chill hours (32-45°F dormancy window). West Virginia 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
Pacific Madrone likes near-neutral soil (pH 4.5-7.4). That's the common-ground band across West Virginia's shale-derived and sandy loam — a soil test confirms it for your site.
Your land, not the state average
West Virginia's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel. What matters for pacific madrone is the horizon its roots actually work, not the surface. That map unit, not the state average, decides how pacific madrone performs.

What Else to Consider for Pacific Madrone in West Virginia
Zone compatibility tells you about winter cold survival — but West Virginia growers also need to think about:
Steep terrain limits usable growing area
Thin acidic soils over shale bedrock
Short mountain valley growing seasons
Growing pacific madrone here specifically
Pacific Madrone wants pH 4.5–7.4 and rates to USDA zones 9–13, but West Virginia's soils are dominantly silt loam — the fit is decided by your parcel's own map unit, not the state average.
Match pacific madrone to your parcel's SSURGO map unit — test pH and texture, and amend toward its 4.5–7.4 range. How to handle it →
What to actually do about these — and the constraints that apply to every West Virginia grower, not just pacific madrone — is covered on the West Virginia growing guide.
Timing shifts within West Virginia
West Virginia isn't one climate. In Pocahontas County, the last hard freeze (28°F) holds until about Apr 30 — roughly 20 days later than the recorded state median — so plant pacific madrone 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 West Virginia Pacific Madrone Is Zone-Hardy
Pacific Madrone is rated for USDA zones 9–13. No West Virginia county reaches it. Even Wyoming County, the state’s mildest winter at zone 7a, sits below the plant’s zone 9 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 55 counties West Virginia’s winter-low ladder runs from zone 6a in Hardy County to zone 7a in Wyoming County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. None of that range reaches the band pacific madrone needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Pacific Madrone’s zone 9–13 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
Pacific Madrone draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pacific madrone can only work that bloom inside West Virginia's frost window — roughly 204 days, opening after the last 28°F freeze (Apr 4 - Apr 15) and closing at the first (Oct 26 - Nov 5), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Pacific Madrone in West Virginia
When can I plant Pacific Madrone in West Virginia?
West Virginia's last spring hard freeze (28°F) clears between Apr 4 and Apr 15, and the first fall hard freeze lands between Oct 26 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Pacific Madrone, so this page does not state whether it overwinters in West Virginia 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 Pacific Madrone grown in across West Virginia?
West Virginia spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Pacific Madrone carries a range of zones 9-13, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical West Virginia site have?
A typical West Virginia site sees ~204 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Pacific Madrone 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 Pocahontas, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Pacific Madrone native to West Virginia?
