Dunedin, Florida, sits in USDA hardiness zone 10a — a zone band wide enough that plant choice, not possibility, is the interesting question.
The conditions favor artichoke, meyer lemon, california poppy, and cabbage, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Dunedin, 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 Dunedin 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 Dunedin
Each reading below is measured for Dunedin itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredDunedin sits in USDA hardiness zone 10a.
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.

Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Your land is one point inside Dunedin
Everything above resolves to Dunedin as a whole — one PHZM band and one 28°F frost record, read across 7K acres. 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 city 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 Dunedin
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals, with the labelled statewide window where none resolves; 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 city grain anywhere on this page — there is no city-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 Dunedin
When does frost risk typically end in Dunedin?
Dunedin has no hard-freeze normal of its own, so it follows Florida's statewide window: the middle half of counties see their last spring hard freeze (28°F) around Jan 25 - Feb 10 and their first fall hard freeze around Dec 7 - Dec 18, per NOAA Regional Climate Centers ACIS (1991–2020). Frost dates shift with elevation and local microclimate, so watch your own site's cold pockets. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
Is the soil safe to grow vegetables in Dunedin?
The federal record around Dunedin is a meaningful one — 1,630 documented sites, mostly Underground Storage Tanks entries (754), the nearest PFAS record about 0.2 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 Dunedin?
As the season closes around Florida's statewide first fall hard freeze (28°F) near Dec 7 - Dec 18 (NOAA Regional Climate Centers ACIS (1991–2020)), 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 the first hard night. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
