Unlikely — Zone Mismatch
Florida anise (zones 7-10) does not overlap with North Dakota's zone range (3b-4b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Florida Anise is hardy to zone 7, and the warmest ground in North Dakota is zone 5 — 2 zones short. Planted in open ground it will not survive a North Dakota winter. To grow it here, grow florida anise in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

North Dakota is not one climate
North Dakota’s winter-low ladder runs across 53 counties, from zone 3.5 in Bottineau County to zone 4.5 in Stutsman County. That is 10°F between the two counties’ average coldest night — the difference between florida anise overwintering in the ground and coming under cover.
The middle half of 53 counties runs 4–4 zones, with a median of 4 zones — a 1-zone span end to end.
Measured across 53 North Dakota counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Florida Anise Stands in North Dakota
Florida Anise is rated for zones 7–10 — a cold floor USDA puts at 0 to 10°F. No North Dakota county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about North Dakota winters, not about florida anise.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Florida Anise in North Dakota
The frost window
Across North Dakota, the last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 151-day window you can count on — up to 162 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
North Dakota runs as cold as USDA zone 3, and no sourced winter-hardiness floor is on record for florida anise, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether florida anise is a permanent planting or a replant-every-spring crop for you turns on your own zone within North Dakota; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. 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 florida anise does not survive a North Dakota winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on North Dakota under protection.
Frost-free days
Florida Anise wants 200+ frost-free days; a typical North Dakota site sees ~157 (NOAA Regional Climate Centers ACIS, 1991-2020) — 43 days short of what it needs. A typical North Dakota 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.
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
Florida Anise likes near-neutral soil (pH 4.5-6.5). That's the common-ground band across North Dakota's prairie loam and clay (red river valley) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5 and 6 — worth knowing before you decide whether a North Dakota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your North Dakota site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
North Dakota soil pH runs about 7.0–7.5, and that sits above florida anise's tolerated 4.5–6.5, so the typical North Dakota parcel needs sulfur to bring it down. SSURGO maps it swinging by full points parcel to parcel, so your map unit, not the state number, decides whether florida anise needs lime or sulfur.

What Else to Consider for Florida Anise in North Dakota
Zone compatibility tells you about winter cold survival — but North Dakota growers also need to think about:
Extreme cold (-40F) and short growing season
Persistent wind desiccates plants
Low rainfall in western ND
Growing florida anise here specifically
Florida Anise does best acidic (pH 4.5–6.5); North Dakota soils average near pH 7.2, alkaline enough to yellow its leaves as micronutrients lock away.
Work in elemental sulfur or acidic organic matter to pull your parcel toward pH 4.5–6.5, then retest. How to handle it →
What to actually do about these — and the constraints that apply to every North Dakota grower, not just florida anise — is covered on the North Dakota growing guide.
Timing shifts within North Dakota
Florida Anise needs about 200 days of frost-free season to complete its cycle. No North Dakota county gives it that outdoors: even Richland County, the state’s longest season at 170 frost-free days, falls 30 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"). Florida Anise's 200-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Florida Anise draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, florida anise can only work that bloom inside North Dakota's frost window — roughly 157 days, opening after the last 28°F freeze (Apr 30 - May 6) and closing at the first (Oct 4 - Oct 9), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Florida Anise
Florida Anise is listed as toxic to dogs, cats (all) at a severe level (Cornell). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.

Common Questions About Growing Florida Anise in North Dakota
When can I plant Florida Anise in North Dakota?
North Dakota's last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Florida Anise, so this page does not state whether it overwinters in North Dakota 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 Florida Anise grown in across North Dakota?
North Dakota spans USDA hardiness zones 3b-4b (USDA ARS PHZM 2023). Florida Anise 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 North Dakota site have?
A typical North Dakota site sees ~157 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Florida Anise needs 200+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Florida Anise native to North Dakota?
Florida Anise is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in North Dakota. It can still earn a place in a North Dakota garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Florida Anise in North Dakota?
Florida Anise prefers pH 4.5-6.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across North Dakota soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
