Conditional — Some Areas
creosote bush (zones 7-10) reaches only part of Ohio (5b-7a): zone 7 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Ohio spans zones 5b-7a, 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 creosote bush against your parcel's actual hardiness, soil, and sun.

When to Plant Creosote Bush in Ohio
The frost window
Across Ohio, the last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 201-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
Ohio runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for creosote bush, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether creosote bush is a permanent planting or a replant-every-spring crop for you turns on your own zone within Ohio; 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 creosote bush survives winter in part of Ohio, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Creosote Bush wants 250+ frost-free days; a typical Ohio site sees ~208 (NOAA Regional Climate Centers ACIS, 1991-2020) — 42 days short of what it needs. A typical Ohio season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Chill hours
Creosote Bush has no winter-chill requirement — its listed minimum is 0 hours (USDA PLANTS Database). Ohio typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), so chill is not a constraint on this plant here — and not evidence in its favour either. Winter survival and season length are what decide it.
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
Creosote Bush likes near-neutral soil (pH 7-8.5). That's the common-ground band across Ohio's glacial till and clay loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 7 and 8 — worth knowing before you decide whether a Ohio soil test result is a problem or just a number. Drainage requirement: excessive (dry/moderately dry). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.

What Else to Consider for Creosote Bush in Ohio
Zone compatibility tells you about winter cold survival — but Ohio growers also need to think about:
Heavy clay soils across much of northern Ohio require amendment for drainage
Variable spring weather with late frost risk through mid-May
Japanese beetles and tomato hornworms are common garden pests
Wet springs can delay planting and promote root rot
What to actually do about these — and the constraints that apply to every Ohio grower, not just creosote bush — is covered on the Ohio growing guide.
Timing shifts within Ohio
Creosote Bush needs about 250 days of frost-free season to complete its cycle. No Ohio county gives it that outdoors: even Cuyahoga County, the state’s longest season at 239 frost-free days, falls 11 days short — so it needs transplants, a short-season variety, or covered growing.
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"). Creosote Bush's 250-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Ohio Fits Best
Even within Ohio's zones 5b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for creosote bush (USDA PHZM 2023):
Pollinator + Wildlife Value
Creosote Bush draws native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, creosote bush can only work that bloom inside Ohio's frost window — roughly 208 days, opening after the last 28°F freeze (Apr 5 - Apr 13) and closing at the first (Oct 31 - Nov 6), per NOAA Regional Climate Centers ACIS, 1991-2020.
Ohio Cooperative Extension
For Ohio-specific cultivar recommendations, planting calendars, and pest pressure for creosote bush, the canonical source is Ohio State University Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Creosote Bush native to Ohio?
Creosote Bush is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Ohio. It can still earn a place in a Ohio garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Creosote Bush in Ohio
When can I plant Creosote Bush in Ohio?
Ohio's last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Creosote Bush, so this page does not state whether it overwinters in Ohio 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 Creosote Bush grown in across Ohio?
Ohio spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Creosote Bush carries a range of zones 7-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Ohio site have?
A typical Ohio site sees ~208 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Creosote Bush needs 250+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Creosote Bush native to Ohio?
Creosote Bush is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Ohio. It can still earn a place in a Ohio garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Creosote Bush in Ohio?
Creosote Bush prefers pH 7-8.5 and excessive (dry/moderately dry) drainage (Growable Ground Plant Database). That sits in the common-ground band across Ohio soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
