Unlikely — Zone Mismatch
chuparosa (zones 9-11) does not overlap with Indiana's zone range (5b-7b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Chuparosa is hardy to zone 9, and the warmest ground in Indiana is zone 7 — 2 zones short. Planted in open ground it will not survive a Indiana winter. To grow it here, grow chuparosa in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

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 chuparosa 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 Chuparosa Stands in Indiana
Chuparosa is rated for zones 9–11 — a cold floor USDA puts at 20 to 30°F. No Indiana 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 Indiana winters, not about chuparosa.

Winter cold is the limit here — the same plant works in a container that comes under cover.
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 Chuparosa 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 chuparosa, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether chuparosa 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.
Timing tuned to sub-state frost dates — Steuben County, not the statewide average.
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.
Soil + Drainage Fit
Chuparosa likes near-neutral soil (pH 5.5-7.8). That's the common-ground band across Indiana's silt loam and clay loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6.5 and 7.5 — worth knowing before you decide whether a Indiana soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Indiana site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.
Your land, not the state average
SSURGO maps about 37.8% of Indiana as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Chuparosa sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Chuparosa 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
Growing chuparosa here specifically
Chuparosa rates to USDA zones 9–11 and takes frost damage on growing tissue around 30°F (FAO ECOCROP), but cold isn't the risk in Indiana — wet is: with roughly 37.8% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give chuparosa a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Indiana grower, not just chuparosa — is covered on the Indiana growing guide.
Timing shifts within Indiana
Indiana isn't one climate. In Steuben County, the last hard freeze (28°F) holds until about Apr 18 — roughly 11 days later than the recorded state median — so plant chuparosa to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in Indiana Chuparosa Is Zone-Hardy
Chuparosa is rated for USDA zones 9–11. No Indiana county reaches it. Even Warrick County, the state’s mildest winter at zone 7a, sits below the plant’s zone 9 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 92 counties Indiana’s winter-low ladder runs from zone 5b in Benton County to zone 7a in Warrick County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. None of that range reaches the band chuparosa needs, so here the statewide answer really is the answer.

Pollinator + Wildlife Value
Chuparosa draws hummingbirds, native bees, and butterflies (high value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, chuparosa 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. Pollinator value: We haven't confirmed this against a published source yet.

Is Chuparosa native to Indiana?
Chuparosa is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Indiana. It can still earn a place in a Indiana garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Chuparosa in Indiana
When can I plant Chuparosa 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 Chuparosa, 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 Chuparosa grown in across Indiana?
Indiana spans USDA hardiness zones 5b-7b (USDA ARS PHZM 2023). Chuparosa is listed for zones 9-11, which do not overlap them, so there is no zone in Indiana where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
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). Chuparosa needs 210+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Steuben, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Chuparosa native to Indiana?
Chuparosa is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Indiana. It can still earn a place in a Indiana garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Chuparosa in Indiana?
Chuparosa prefers pH 5.5-7.8 and well (dry spells) drainage. We haven't confirmed this against a published source yet. 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 Chuparosa actually grow on my specific land in Indiana?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores chuparosa against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
