Paradis, Louisiana, sits in USDA hardiness zone 9b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Reliable performers under these conditions include okra, meyer lemon, california poppy, and artichoke; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Paradis, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Paradis lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Paradis
Each reading below is measured for Paradis itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsParadis runs about 337 days between hard freezes (read from St. Charles Parish, the closest normal to Paradis) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredParadis sits in USDA hardiness zone 9b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.
USDA PHZM 2023
The kind of country Paradis is in
Paradis sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Paradis's own centroid rather than borrowed from St. Charles Parish.

Is it too late to plant in Paradis?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 21 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What an experienced grower watches for around here
In and around Paradis, Toxics Release Inventory runs higher than the national average — 34 sites within ~10 miles of Paradis. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.

Your land is one point inside Paradis
Everything above resolves to Paradis as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from St. Charles Parish’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Paradis
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at St. Charles Parish’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Paradis
When does frost risk typically end in Paradis?
The last hard freeze (28°F) in Paradis typically lands around Jan 18, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 8.
When is the first frost in Paradis?
The first hard freeze (28°F) in Paradis typically arrives around Dec 21, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 7, so the watching starts about Nov 21 — about 337 days after the spring freeze cleared.
How long is the growing season in Paradis?
Measured between 28°F hard freezes, Paradis sees about 337 frost-free days — roughly Jan 18 through Dec 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 8 to Dec 7, about 302 days.
Is the soil safe to grow vegetables in Paradis?
The federal record around Paradis is a meaningful one — 357 documented sites, mostly Brownfields entries (148), the nearest Brownfields record about 0.6 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Paradis?
From about Nov 21 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 21 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 21. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
