Generally — Most Areas
jungle rice (zones 7-13) suits most of Arkansas (6b-8b) — zones 7-8 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8b, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score jungle rice against your land's actual soil, sun, and frost.

When to Plant Jungle Rice 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.
Frost tenderness
Jungle Rice is frost-tender — its listed minimum temperature is 42.8°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
When to start the seed
Jungle Rice is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Arkansas's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
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 jungle rice survives winter in part of Arkansas, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Jungle Rice wants 45+ frost-free days; a typical Arkansas site sees ~254 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
Jungle Rice 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 poorly (saturated >50% of year), 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 Jungle Rice 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 jungle rice — is covered on the Arkansas growing guide.
Timing shifts within Arkansas
Jungle Rice needs about 45 days of frost-free season to complete its cycle. Even Benton County — Arkansas’s shortest season at 226 frost-free days — clears that by 181 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"). Jungle Rice's 45-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 jungle rice (USDA PHZM 2023):
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for jungle rice, 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 Jungle Rice native to Arkansas?
No — the USDA PLANTS Database lists Jungle Rice 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 Jungle Rice in Arkansas
When can I plant Jungle Rice 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). Jungle Rice is frost-tender — its listed minimum temperature is 42.8°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
What hardiness zone is Jungle Rice grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Jungle Rice carries a range of zones 7-13, 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). Jungle Rice needs 45+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Jungle Rice native to Arkansas?
No — the USDA PLANTS Database lists Jungle Rice 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 Jungle Rice in Arkansas?
Jungle Rice prefers pH 5-7 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). 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 Jungle Rice actually grow on my specific land in Arkansas?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores jungle rice against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
