Generally — Most Areas
red yucca (zones 6-10) suits most of Oregon (5a-10a) — zones 6-10 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Oregon spans zones 5a-10a, 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 red yucca against your parcel's actual hardiness, soil, and sun.

When to Plant Red Yucca in Oregon
The frost window
Across Oregon, the last spring hard freeze (28°F) clears between Feb 25 and Apr 26, and the first fall hard freeze lands between Oct 19 and Nov 26 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 176-day window you can count on — up to 274 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
Oregon runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for red yucca, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether red yucca is a permanent planting or a replant-every-spring crop for you turns on your own zone within Oregon; 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.
Soil + Drainage Fit
Red Yucca tolerates a wide pH range (pH 5.1-9) — 3.9 units, acid ground through alkaline — so soil acidity is rarely what limits it in Oregon. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6.8 and 7.2 — worth knowing before you decide whether a Oregon 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 Red Yucca in Oregon
Zone compatibility tells you about winter cold survival — but Oregon growers also need to think about:
West side: excessive rain and overcast skies reduce sun for warm-season crops
East side: arid conditions (8-15 inches rainfall) require irrigation
Slug pressure is extreme in western Oregon
Mountain areas have very short seasons (60-90 frost-free days)
What to actually do about these — and the constraints that apply to every Oregon grower, not just red yucca — is covered on the Oregon growing guide.
Where in Oregon Red Yucca Is Zone-Hardy
Red Yucca is rated for USDA zones 6–10. Every one of Oregon’s 36 counties sits inside that band — from Klamath County at zone 6a to Curry County at zone 9b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 36 counties Oregon’s winter-low ladder runs from zone 6a in Klamath County to zone 9b in Curry County — 3.5 USDA zones of spread, which is 35°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. Klamath County holds its last hard freeze (28°F) until about Jun 9, while Lincoln County is clear by Feb 3 — 126 days apart. Set red yucca 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". Red Yucca’s zone 6–10 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 Oregon Fits Best
Even within Oregon's zones 5a-10a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for red yucca (USDA PHZM 2023):
Pollinator + Wildlife Value
Red Yucca draws hummingbirds and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, red yucca can only work that bloom inside Oregon's frost window — roughly 213 days, opening after the last 28°F freeze (Feb 25 - Apr 26) and closing at the first (Oct 19 - Nov 26), per NOAA Regional Climate Centers ACIS, 1991-2020.

Is Red Yucca native to Oregon?
Red Yucca is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Oregon. It can still earn a place in a Oregon garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Red Yucca in Oregon
When can I plant Red Yucca in Oregon?
Oregon's last spring hard freeze (28°F) clears between Feb 25 and Apr 26, and the first fall hard freeze lands between Oct 19 and Nov 26 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Red Yucca, so this page does not state whether it overwinters in Oregon 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 Red Yucca grown in across Oregon?
Oregon spans USDA hardiness zones 5a-10a (USDA ARS PHZM 2023). Red Yucca carries a range of zones 6-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Oregon site have?
A typical Oregon site sees ~213 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Red Yucca 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.
Is Red Yucca native to Oregon?
Red Yucca is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Oregon. It can still earn a place in a Oregon garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Red Yucca in Oregon?
Red Yucca tolerates pH 5.1-9 and excessive (dry/moderately dry) drainage (Growable Ground Plant Database). That is a 3.9-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Oregon site — amend for drainage and organic matter first.
Will Red Yucca actually grow on my specific land in Oregon?
