Conditional — Some Areas
sorrel (zones 3-7) reaches only part of Texas (6b-10b): zones 6-7 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Texas spans zones 6b-10b, 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 sorrel against your parcel's actual hardiness, soil, and sun.

When to Plant Sorrel in Texas
The frost window
Across Texas, the last spring hard freeze (28°F) clears between Feb 10 and Mar 12, and the first fall hard freeze lands between Nov 18 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 251-day window you can count on — up to 297 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.
When to start the seed
Those dates are when sorrel goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from Texas's late-side last freeze of Mar 12 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Winter standing
Texas runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for sorrel, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether sorrel is a permanent planting or a replant-every-spring crop for you turns on your own zone within Texas; 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 sorrel survives winter in part of Texas, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Days to maturity
Sorrel matures in ~60 days (Growable Ground Plant Database). A typical Texas site has ~274 frost-free days, so plenty of room for a second succession.
Growing degree days
Sorrel needs ~900 GDD (base 50°F) to ripen. The state median runs ~5834 GDD (from PRISM 1991-2020 climate normals), so Texas's typical season clears that easily.
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
Sorrel likes near-neutral soil (pH 5-7). That's the common-ground band across Texas's black clay (blackland prairie) 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 6.8 — worth knowing before you decide whether a Texas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Texas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Sorrel in Texas
Zone compatibility tells you about winter cold survival — but Texas growers also need to think about:
Extreme heat (100F+ days) stresses many crops from June through September
Rainfall varies dramatically — 8 inches in west TX to 56 inches in east TX
Heavy black clay (Blackland Prairie) is difficult to work and drains poorly
Flash drought conditions can develop rapidly even in wet years
What to actually do about these — and the constraints that apply to every Texas grower, not just sorrel — is covered on the Texas growing guide.
Timing shifts within Texas
Sorrel needs about 60 days of frost-free season from planting to harvest. Even Dallam County — Texas’s shortest season at 197 frost-free days — clears that by 137 days, so season length isn’t the constraint anywhere in Texas. What varies is your own parcel.
Across Texas’s 254 counties the frost-free season runs from 197 days in Dallam County to 343 days in Kenedy County — a spread of 146 days, which is why a single statewide planting date misleads. The median Texas county sees 274 frost-free days, leaving sorrel about 214 days of slack on a typical parcel — room for a second sowing where the season runs long.
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"). Sorrel's 60-day requirement: USDA PLANTS / Growable Ground plant database (days to maturity). A parcel report resolves your address's own frost dates.
Where in Texas Fits Best
Even within Texas's zones 6b-10b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for sorrel (USDA PHZM 2023):
Texas Cooperative Extension
For Texas-specific cultivar recommendations, planting calendars, and pest pressure for sorrel, the canonical source is Texas A&M AgriLife Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Sorrel native to Texas?
No — the USDA PLANTS Database lists Sorrel as introduced rather than native in the Lower 48, so it is not part of Texas's native flora. It grows here as a garden plant; pairing it with a few Texas natives keeps local pollinators fed too.

Common Questions About Growing Sorrel in Texas
When can I plant Sorrel in Texas?
Texas's last spring hard freeze (28°F) clears between Feb 10 and Mar 12, and the first fall hard freeze lands between Nov 18 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Sorrel, so this page does not state whether it overwinters in Texas 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 Sorrel grown in across Texas?
Texas spans USDA hardiness zones 6b-10b (USDA ARS PHZM 2023). Sorrel carries a range of zones 3-7, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Texas site have?
A typical Texas site sees ~274 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Sorrel 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 Sorrel native to Texas?
No — the USDA PLANTS Database lists Sorrel as introduced rather than native in the Lower 48, so it is not part of Texas's native flora. It grows here as a garden plant; pairing it with a few Texas natives keeps local pollinators fed too.
How should I amend the soil for Sorrel in Texas?
Sorrel prefers pH 5-7 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Texas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
