Conditional — Some Areas
yarrow (zones 4-10) has limited zone overlap with Arkansas (6b-8a). Only zones 6-8 in the state are suitable.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8a, 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 yarrow against your parcel's actual hardiness, soil, and sun.

When to Plant Yarrow in Arkansas
The frost window
Across Arkansas, the last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 183-day window you can count on — up to 240 days on a mild site in a kind year.
Frost hardiness
Yarrow is cold-hardy to -38°F (USDA PLANTS Database), so you can plant on the early side of Arkansas's window — even a few weeks before the final frost date.
Establishment timing
As a long-lived plant, yarrow isn't racing the calendar to a harvest date. Plant it in spring once the last-frost window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
Timing tuned to sub-state frost dates — Fulton County, not the statewide average.
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
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Yarrow wants 0+ frost-free days; a typical Arkansas site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Yarrow likes near-neutral soil (pH 6-8). That's the common-ground band across Arkansas's silt loam and sandy loam — a soil test confirms it for your site. 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.
Your land, not the state average
Whether yarrow thrives in Arkansas comes down to drainage, and SSURGO drainage class flips from well-drained to poorly-drained parcel to parcel — your soil map unit, not the state average, is the real answer.

Yarrow in Arkansas — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 4-10 (USDA PLANTS Database)
- State Zones: 6b-8a (USDA ARS PHZM 2023)
- Growing Season: Mar 15 - Apr 15 to Oct 15 - Nov 10 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Morning base-watering, wide spacing, and resistant varieties keep disease manageable — your extension lists what holds up here.
Heavy clay soils in parts of the Ozarks
A raised bed gets you growing this season; compost worked in each fall opens the clay for the long run.
Severe spring storms and hail risk
Keep row cover staged through storm season — five minutes of shelter can save a bed of seedlings from hail.
Growing yarrow here specifically
Yarrow rates to USDA zones 4–10 and is hardy to about -38°F, but cold isn't the risk in Arkansas — wet is: with roughly 33.9% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give yarrow a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
Timing shifts within Arkansas
Arkansas isn't one climate. In Fulton County, the last hard freeze (28°F) holds until about Mar 1 — roughly 19 days later than the recorded state median — so plant yarrow to your county's window, not the statewide date.
County last-freeze dates: NOAA/PRISM Climate Normals 1991-2020, 28°F threshold (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Yarrow draws pollinators (high value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Deer pressure is meaningful across much of Arkansas; yarrow is listed as deer-resistant (USDA PLANTS Database), which makes it a safer pick for unfenced sites. Our deer & wildlife guide carries the full deer-resistant list and how to protect the rest.
Recommended Yarrow Varieties for Arkansas
Arkansas publishes no state variety trial for yarrow, so we won't invent a "best for Arkansas" list. Choose types rated to your USDA hardiness zone (6b-8a), and confirm winter survival and drainage against your own parcel.
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for yarrow, 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 Yarrow native to Arkansas?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Yarrow as native to Arkansas. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Yarrow in Arkansas
When can I plant Yarrow in Arkansas?
Arkansas's last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Yarrow is a long-lived planting, so target spring just after your local last frost — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Yarrow grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8a (USDA ARS PHZM 2023). Yarrow carries a range of zones 4-10, 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 ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Yarrow needs 0+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Fulton, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Yarrow native to Arkansas?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Yarrow as native to Arkansas. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Yarrow in Arkansas?
Yarrow prefers pH 6-8 and well (dry spells) drainage (USDA PLANTS 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.
