Generally — Most Areas
rose (zones 5-11) suits most of Vermont (4a-6a) — zones 5-6 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Vermont spans zones 4a-6a, 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 rose against your parcel's actual hardiness, soil, and sun.

When to Plant Rose 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 rose, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether rose 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.
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 rose survives winter in part of Vermont, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Chill hours
Rose requires ~500 chill hours (32-45°F dormancy window). Vermont 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
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.

What Else to Consider for Rose 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
What to actually do about these — and the constraints that apply to every Vermont grower, not just rose — is covered on the Vermont growing guide.
Where in Vermont Rose Is Zone-Hardy
Rose is rated for USDA zones 5–11. 9 of Vermont’s 14 counties fall inside that band. The coldest that does is Addison County at zone 5a. 5 counties sit below the plant’s zone 5 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in Vermont decides this one.
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 rose 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". Rose’s zone 5–11 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Where in Vermont Fits Best
Even within Vermont's zones 4a-6a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for rose (USDA PHZM 2023):
Pollinator + Wildlife Value
Rose draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, rose 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.

What pests threaten rose in Vermont?
Japanese beetle is documented in Vermont, and it hits rose where it counts. Here is what it actually does — and the move that beats it.
Japanese beetle
Act on thisRose is at the top of the Japanese beetle's preferred-plant list, and it is the one case where 'cosmetic' misses the point: the University of Minnesota notes healthy roses survive the feeding, but the blossoms are often ruined — the thing you grow the plant for.
What to do: Handpick or knock beetles into a bucket of soapy water, daily, in the cool of morning or evening — damaged leaves release an odor that pulls in more beetles, so removing them lowers next week's numbers. Handpick while the plant is in bloom, then net it once flowering is done. Skip the pheromone traps: University of Kentucky research found they draw in more beetles than they catch.

Common Questions About Growing Rose in Vermont
When can I plant Rose 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 Rose, 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 Rose grown in across Vermont?
Vermont spans USDA hardiness zones 4a-6a (USDA ARS PHZM 2023). Rose carries a range of zones 5-11, 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). Rose 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.
Will Rose actually grow on my specific land in Vermont?
