Unlikely — Zone Mismatch
chuparosa (zones 9-11) does not overlap with Michigan's zone range (4a-7a). 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 Michigan is zone 7 — 2 zones short. Planted in open ground it will not survive a Michigan winter. To grow it here, grow chuparosa under glass — a greenhouse is the only lift this wide the engine models.

When to Plant Chuparosa in Michigan
The frost window
Across Michigan, the last spring hard freeze (28°F) clears between Apr 19 and May 8, and the first fall hard freeze lands between Oct 12 and Oct 31 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 157-day window you can count on — up to 195 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
Michigan runs as cold as USDA zone 4, 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 Michigan; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Luce County, not the statewide average.
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
The zone check says chuparosa does not survive a Michigan 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 Michigan under protection.
Frost-free days
Chuparosa wants 210+ frost-free days; a typical Michigan site sees ~186 (NOAA Regional Climate Centers ACIS, 1991-2020) — 24 days short of what it needs. A typical Michigan 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
Chuparosa likes near-neutral soil (pH 5.5-7.8). That's the common-ground band across Michigan's sandy 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 Michigan soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Michigan site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 29.4% of Michigan 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.

Chuparosa in Michigan — Quick Answer

- Plant Zones: 9-11 (USDA PLANTS Database)
- State Zones: 4a-7a (USDA ARS PHZM 2023)

What Else to Consider for Chuparosa in Michigan
Zone compatibility tells you about winter cold survival — but Michigan growers also need to think about:
Lake effect weather creates highly localized microclimates
Short northern season (100-120 frost-free days in UP)
Sandy soils in western MI drain too quickly
Growing chuparosa here specifically
Chuparosa rates to USDA zones 9–11 and is hardy to about 53°F, but cold isn't the risk in Michigan — wet is: with roughly 29.4% 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 Michigan grower, not just chuparosa — is covered on the Michigan growing guide.
Timing shifts within Michigan
Michigan isn't one climate. In Luce County, the last hard freeze (28°F) holds until about May 22 — roughly 27 days later than the recorded state median — so plant chuparosa to your county's window, not the statewide date.
Chuparosa needs about 210 days of frost-free season to complete its cycle. 3 of Michigan’s 83 counties give it that outright. The tightest that does is Leelanau County at 210 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Michigan’s 83 counties the frost-free season runs from 126 days in Iron County to 223 days in Berrien County — a spread of 97 days, which is why a single statewide planting date misleads. The median Michigan county sees 186 frost-free days, which is 24 days short of what chuparosa needs — so on a typical Michigan parcel this is a transplant-or-protect crop, not a direct-sow one.
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"). Chuparosa's 210-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
Chuparosa draws hummingbirds, native bees, and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, chuparosa can only work that bloom inside Michigan's frost window — roughly 186 days, opening after the last 28°F freeze (Apr 19 - May 8) and closing at the first (Oct 12 - Oct 31), per NOAA Regional Climate Centers ACIS, 1991-2020.

For Michigan-specific cultivar recommendations, planting calendars, and pest pressure for chuparosa, the canonical source is MSU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Chuparosa native to Michigan?
Chuparosa is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Michigan. It can still earn a place in a Michigan garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Chuparosa in Michigan
When can I plant Chuparosa in Michigan?
Michigan's last spring hard freeze (28°F) clears between Apr 19 and May 8, and the first fall hard freeze lands between Oct 12 and Oct 31 (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 Michigan 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 Michigan?
Michigan spans USDA hardiness zones 4a-7a (USDA ARS PHZM 2023). Chuparosa carries a range of zones 9-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Michigan site have?
A typical Michigan site sees ~186 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 Luce, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Chuparosa native to Michigan?
Chuparosa is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Michigan. It can still earn a place in a Michigan garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Chuparosa in Michigan?
Chuparosa prefers pH 5.5-7.8 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Michigan 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 Michigan?
