Conditional — Some Areas
catmint (zones 3-8) has limited zone overlap with North Dakota (3a-4b). Only zones 3-4 in the state are suitable.
Your yard isn't the whole zone.
North Dakota spans zones 3a-4b, 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 catmint against your land's actual soil, sun, and frost.

When to Plant Catmint in North Dakota
The frost window
Across North Dakota, the last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 1 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 101-day window you can count on — up to 149 days on a mild site in a kind year.
Frost tenderness
Catmint is frost-tender — its listed minimum temperature is 39.2°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
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
Catmint wants 150+ frost-free days; a typical North Dakota site sees ~130 (NOAA Climate Normals). That leaves tight; use transplants and pick early-maturing cultivars.
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
Catmint likes near-neutral soil (pH 4.9-7.5). 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. 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.

What Else to Consider
Zone compatibility tells you about winter cold survival — but North Dakota growers also need to think about:
Extreme cold (-40F) and short growing season
Cold-proven varieties plus a high tunnel make North Dakota's short season dependable — northern growers' standard kit.
Persistent wind desiccates plants
A windbreak is the highest-return structure on the northern plains — even a snow fence changes what survives.
Low rainfall in western ND
Out west, drip irrigation and mulch decide the season — set the water system up front.
Pollinator + Wildlife Value
Catmint 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 North Dakota; catmint 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.

Common Questions About Growing Catmint in North Dakota
When can I plant Catmint in North Dakota?
North Dakota's last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 1 (NOAA Climate Normals 1991-2020). Catmint is frost-tender — its listed minimum temperature is 39.2°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
What hardiness zone is Catmint grown in across North Dakota?
North Dakota spans USDA hardiness zones 3a-4b (USDA ARS PHZM 2023). Catmint carries a range of zones 3-8, 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 ~130 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Catmint needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Catmint in North Dakota?
Catmint prefers pH 4.9-7.5 and well (dry spells) drainage (USDA PLANTS 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.
Will Catmint actually grow on my specific land in North Dakota?
