Japanese Mint is grown for its foliage and the structure it brings to a planting. It's hardy across USDA zones 11 through 13 and shrugs off deer. Its spring flowers are a moderate draw for honeybees and native bees.

What Japanese Mint is
Japanese Mint grows as a perennial. It blooms white in spring. It's also deer-resistant.
How to grow Japanese Mint
Japanese Mint grows in USDA zones 11 through 13. Japanese Mint does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 8.3, on well-drained ground.

Start the season right
Plant japanese mint in full sun with at least 6 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat.
Match the soil
Japanese Mint prefers pH 4.5 to 8.3 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Keep it in good form
Prune japanese mint to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Where Japanese Mint thrives
Japanese Mint is hardy across USDA zones 11 through 13. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 11–13 spans average winter lows from 40°F to 70°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 3 down the middle — and which side of that line your land sits on changes the answer.

Where Japanese Mint stands, state by state
Japanese Mint is rated for zones 11–13 — a cold floor USDA puts at 40 to 50°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 3 more, and 48 sit outside it — and inside every split state, the same line runs on at county grain.

Japanese Mint’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.
State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

How we know this about Japanese Mint
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Japanese Mint in my zone?
Japanese Mint grows in USDA hardiness zones 11 through 13. Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Japanese Mint?
Japanese Mint is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Japanese Mint need?
Japanese Mint needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Japanese Mint need?
Japanese Mint prefers soil pH 4.5 to 8.3, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Japanese Mint attract pollinators?
Yes — japanese mint's flowers are a solid nectar source for honeybees and native bees. (Source: Pollinator Partnership.)
