Yes — Strong Match
dawn redwood (zones 4-8) covers every zone Arkansas contains (6b-8b), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8b, 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 dawn redwood against your parcel's actual hardiness, soil, and sun.

When to Plant Dawn Redwood in Arkansas
The frost window
Across Arkansas, the last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 240-day window you can count on — up to 266 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
Arkansas runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for dawn redwood, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether dawn redwood is a permanent planting or a replant-every-spring crop for you turns on your own zone within Arkansas; 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 dawn redwood survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Dawn Redwood wants 200+ frost-free days; a typical Arkansas site sees ~254 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Chill hours
Dawn Redwood requires ~400 chill hours (32-45°F dormancy window). Arkansas typically banks ~1780 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
Dawn Redwood likes near-neutral soil (pH 5-7). That's the common-ground band across Arkansas's silt loam and sandy loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a Arkansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Arkansas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Dawn Redwood in Arkansas
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Heavy clay soils in parts of the Ozarks
Severe spring storms and hail risk
What to actually do about these — and the constraints that apply to every Arkansas grower, not just dawn redwood — is covered on the Arkansas growing guide.
Timing shifts within Arkansas
Dawn Redwood needs about 200 days of frost-free season to complete its cycle. Even Benton County — Arkansas’s shortest season at 226 frost-free days — clears that by 26 days, so season length isn’t the constraint anywhere in Arkansas. What varies is your own parcel.
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"). Dawn Redwood's 200-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Arkansas Fits Best
Even within Arkansas's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for dawn redwood (USDA PHZM 2023):
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for dawn redwood, the canonical source is University of Arkansas Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Dawn Redwood native to Arkansas?
No — the USDA PLANTS Database lists Dawn Redwood as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.

Common Questions About Growing Dawn Redwood in Arkansas
When can I plant Dawn Redwood in Arkansas?
Arkansas's last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Dawn Redwood, so this page does not state whether it overwinters in Arkansas 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 Dawn Redwood grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Dawn Redwood carries a range of zones 4-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Arkansas site have?
A typical Arkansas site sees ~254 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Dawn Redwood needs 200+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Dawn Redwood native to Arkansas?
No — the USDA PLANTS Database lists Dawn Redwood as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.
How should I amend the soil for Dawn Redwood in Arkansas?
Dawn Redwood prefers pH 5-7 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Arkansas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Dawn Redwood actually grow on my specific land in Arkansas?
