Unlikely — Zone Mismatch
jade plant (zones 11-12) does not overlap with Mississippi's zone range (7b-9b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Jade Plant is hardy to zone 11, and the warmest ground in Mississippi is zone 9 — 2 zones short. Planted in open ground it will not survive a Mississippi winter. To grow it here, grow jade plant in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

Mississippi is not one climate
Mississippi’s winter-low ladder runs across 82 counties, from zone 7.5 in Benton County to zone 9 in Wilkinson County. That is 15°F between the two counties’ average coldest night — the difference between jade plant overwintering in the ground and coming under cover.
The middle half of 82 counties runs 8–8.5 zones, with a median of 8.5 zones — a 1.5-zone span end to end.

Where Jade Plant Stands in Mississippi
Jade Plant is rated for zones 11–12 — a cold floor USDA puts at 40 to 50°F. No Mississippi 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 Mississippi winters, not about jade plant.

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 Jade Plant in Mississippi
The frost window
Across Mississippi, the last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 263-day window you can count on — up to 286 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
Mississippi runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for jade plant, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether jade plant is a permanent planting or a replant-every-spring crop for you turns on your own zone within Mississippi; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Tishomingo 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
Jade Plant likes near-neutral soil (pH 5.5-7). That's the common-ground band across Mississippi's loess and alluvial clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 6.5 — worth knowing before you decide whether a Mississippi soil test result is a problem or just a number. Drainage requirement: excessive (dry/moderately dry). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.
Your land, not the state average
SSURGO maps about 30.3% of Mississippi as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Jade Plant tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

What Else to Consider for Jade Plant in Mississippi
Zone compatibility tells you about winter cold survival — but Mississippi growers also need to think about:
Extreme summer heat and humidity
Heavy alluvial clay in the Delta region
Frequent severe storms and flooding
Growing jade plant here specifically
Jade Plant likes pH 5.5–7.0 and its growing tissue burns around 35°F (FAO ECOCROP), yet neither saves it from wet feet — SSURGO maps about 30.3% of Mississippi poorly-drained, where its crown sit and rot.
Set jade plant high on bermed, grit-amended ground so winter and storm water drain away from the crown. How to handle it →
What to actually do about these — and the constraints that apply to every Mississippi grower, not just jade plant — is covered on the Mississippi growing guide.
Timing shifts within Mississippi
Mississippi isn't one climate. In Tishomingo County, the last hard freeze (28°F) holds until about Mar 23 — roughly 26 days later than the recorded state median — so plant jade plant 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 Mississippi Jade Plant Is Zone-Hardy
Jade Plant is rated for USDA zones 11–12. No Mississippi county reaches it. Even Wilkinson County, the state’s mildest winter at zone 9a, sits below the plant’s zone 11 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 82 counties Mississippi’s winter-low ladder runs from zone 7b in Benton County to zone 9a in Wilkinson 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 jade plant needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Jade Plant’s zone 11–12 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Jade Plant draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, jade plant can only work that bloom inside Mississippi's frost window — roughly 273 days, opening after the last 28°F freeze (Feb 17 - Mar 3) and closing at the first (Nov 21 - Nov 30), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Jade Plant
Jade Plant is listed as toxic to dogs, cats (all) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Parts of jade plant carry minor toxicity for people, so know which parts are edible before harvest.
Mississippi Cooperative Extension
For Mississippi-specific cultivar recommendations, planting calendars, and pest pressure for jade plant, the canonical source is Mississippi State University Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Jade Plant native to Mississippi?
No — the USDA PLANTS Database lists Jade Plant as introduced rather than native in the Lower 48, so it is not part of Mississippi's native flora. It grows here as a garden plant; pairing it with a few Mississippi natives keeps local pollinators fed too.

Common Questions About Growing Jade Plant in Mississippi
When can I plant Jade Plant in Mississippi?
Mississippi's last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Jade Plant, so this page does not state whether it overwinters in Mississippi 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 Jade Plant grown in across Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Jade Plant carries a range of zones 11-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Mississippi site have?
A typical Mississippi site sees ~273 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Jade Plant should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Tishomingo, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Jade Plant native to Mississippi?
No — the USDA PLANTS Database lists Jade Plant as introduced rather than native in the Lower 48, so it is not part of Mississippi's native flora. It grows here as a garden plant; pairing it with a few Mississippi natives keeps local pollinators fed too.
How should I amend the soil for Jade Plant in Mississippi?
Jade Plant prefers pH 5.5-7 and excessive (dry/moderately dry) drainage (Growable Ground Plant Database). That sits in the common-ground band across Mississippi soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
