Your yard isn't the whole zone.
Mississippi spans zones 7b-9b, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score lily against your land's actual soil, sun, and frost.

Mississippi is not one climate
A single Mississippi answer averages 82 counties whose growing seasons are 77 days apart — from 232 frost-free days in Tishomingo County to 309 in Harrison County. Which end of that your land sits nearer changes what lily can finish before the first hard freeze.
The middle half of 82 counties runs 262–286 days, with a median of 272 days — a 77-day span end to end.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Mississippi Fits Best
Lily is rated for zones 4–8 — a cold floor USDA puts at -30 to -20°F. Against Mississippi’s 82 counties that band holds in 31 of them, and the line runs at Benton County (zone 7b), the coldest county still inside it.

Too little winter chill rather than too much cold — a low-chill selection is what changes it.
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.
Even within Mississippi's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for lily (USDA PHZM 2023):

When to Plant Lily 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.
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.
What Else to Consider for Lily 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
What to actually do about these — and the constraints that apply to every Mississippi grower, not just lily — is covered on the Mississippi growing guide.
Where in Mississippi Lily Is Zone-Hardy
Lily is rated for USDA zones 4–8. 31 of Mississippi’s 82 counties fall inside that band. The coldest that does is Benton County at zone 7b. 51 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Mississippi decides this one.
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. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Tishomingo County holds its last hard freeze (28°F) until about Mar 23, while Harrison County is clear by Feb 4 — 47 days apart. Set lily out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Lily’s zone 4–8 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
Lily draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, lily 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.

Common Questions About Growing Lily in Mississippi
When can I plant Lily 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
What hardiness zone is Lily grown in across Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Lily carries a range of zones 4-8, 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). Lily 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.
Will Lily actually grow on my specific land in Mississippi?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores lily against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
