Yes — Strong Match
New Jersey tea (zones 5-11) covers every zone Indiana contains (5b-7b), so hardiness is not what limits it anywhere in the state.

Indiana is not one climate
Indiana’s winter-low ladder runs across 92 counties, from zone 5.5 in Benton County to zone 7 in Warrick County. That is 15°F between the two counties’ average coldest night — the difference between new jersey tea overwintering in the ground and coming under cover.
The middle half of 92 counties runs 6–6.5 zones, with a median of 6 zones — a 1.5-zone span end to end.

Where in Indiana Fits Best
Even within Indiana's zones 5b-7b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for new jersey tea (USDA PHZM 2023):

When to Plant New Jersey Tea in Indiana
The frost window
Across Indiana, the last spring hard freeze (28°F) clears between Apr 4 and Apr 9, and the first fall hard freeze lands between Oct 30 and Nov 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 204-day window you can count on — up to 214 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
Indiana runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for new jersey tea, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether new jersey tea is a permanent planting or a replant-every-spring crop for you turns on your own zone within Indiana; 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 new jersey tea survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
New Jersey Tea wants 120+ frost-free days; a typical Indiana site sees ~209 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Chill hours
New Jersey Tea requires ~600 chill hours (32-45°F dormancy window). Indiana typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
New Jersey Tea likes near-neutral soil (pH 4.3-6.5). That's the common-ground band across Indiana's silt loam and clay loam — a soil test confirms it for your site.
Plant pH requirements: FAO ECOCROP and USDA PLANTS, with the remaining rows from other published sources or Growable Ground compilation. Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Indiana soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
What Else to Consider for New Jersey Tea in Indiana
Zone compatibility tells you about winter cold survival — but Indiana growers also need to think about:
Heavy clay soils limit drainage in many areas
Late spring frosts through early May
Hot humid summers promote blight and mildew
What to actually do about these — and the constraints that apply to every Indiana grower, not just new jersey tea — is covered on the Indiana growing guide.
Timing shifts within Indiana
New Jersey Tea needs about 120 days of frost-free season to complete its cycle. Even Steuben County — Indiana’s shortest season at 191 frost-free days — clears that by 71 days, so season length isn’t the constraint anywhere in Indiana. 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"). New Jersey Tea's 120-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
New Jersey Tea draws honeybees, native bees, and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, new jersey tea can only work that bloom inside Indiana's frost window — roughly 209 days, opening after the last 28°F freeze (Apr 4 - Apr 9) and closing at the first (Oct 30 - Nov 4), per NOAA Regional Climate Centers ACIS, 1991-2020.
Indiana Cooperative Extension
For Indiana-specific cultivar recommendations, planting calendars, and pest pressure for new jersey tea, the canonical source is Purdue Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is New Jersey Tea native to Indiana?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents New Jersey Tea as native to Indiana. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing New Jersey Tea in Indiana
When can I plant New Jersey Tea in Indiana?
Indiana's last spring hard freeze (28°F) clears between Apr 4 and Apr 9, and the first fall hard freeze lands between Oct 30 and Nov 4 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for New Jersey Tea, so this page does not state whether it overwinters in Indiana 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 New Jersey Tea grown in across Indiana?
Indiana spans USDA hardiness zones 5b-7b (USDA ARS PHZM 2023). New Jersey Tea carries a range of zones 5-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Indiana site have?
A typical Indiana site sees ~209 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). New Jersey Tea needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is New Jersey Tea native to Indiana?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents New Jersey Tea as native to Indiana. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for New Jersey Tea in Indiana?
New Jersey Tea prefers pH 4.3-6.5 (USDA PLANTS). That sits in the common-ground band across Indiana soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will New Jersey Tea actually grow on my specific land in Indiana?
