Washington Park, Florida, sits in USDA hardiness zone 11a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Expect artichoke, starfruit, allspice, and cabbage to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Washington Park, 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 Washington Park lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

Washington Park — the short answer
Washington Park, Florida: USDA zone 11a, no 28°F killing freeze on record — the season is year-round, across 166 acres of town.

Every figure names the dataset it came from. The year-round finding is measured — a 30-year record with no 28°F killing freeze in it — never inferred from missing dates.

What this means for growing in Washington Park
Each reading below is measured for Washington Park itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredWashington Park sits in USDA hardiness zone 11a.
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 Washington Park is in
Washington Park sits in the Southern Florida Coastal Plain — EPA Level III, inside the wider Tropical Wet Forests. That is read at Washington Park's own centroid rather than borrowed from Broward County.

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 Washington Park
Everything above resolves to Washington Park as a whole — one PHZM band and one 28°F frost record, read across 166 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 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 Washington Park
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, 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 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 Washington Park
Is it too late to plant in Washington Park?
No — Washington Park has no 28°F killing freeze in the 30-year station record, so the growing season is year-round and there is no last-frost date to wait for. Planting is paced by rainfall, heat and daylength instead of by frost: start heat-lovers any month, and time cool-season crops (lettuce, brassicas, peas) for the cooler, wetter half of the year or for higher ground. Succession sowing every few weeks works all year, so the limit is what you can keep watered and harvested, not the calendar.
When does frost risk typically end in Washington Park?
It doesn't — Washington Park records no 28°F killing freeze at all across the 1991–2020 station record, so there is no spring frost date to plant after. Cold still matters with elevation: the higher you garden, the cooler the nights, and a few tropical crops sulk below about 60°F even where they never freeze.
How long is the growing season in Washington Park?
Year-round — the 1991–2020 station record for Washington Park contains no 28°F killing freeze, so there is no season to measure between freezes. What paces planting instead is heat, rainfall and daylength: the hottest, wettest stretch is the hard part for cool-season crops, not winter. Elevation is the one real exception — the higher you garden, the colder the nights get.
Is the soil safe to grow vegetables in Washington Park?
The federal record around Washington Park runs heavier than most — 4,118 documented sites, mostly Underground Storage Tanks entries (2,036), the nearest Brownfields record about 0.2 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Everything above is measured at Washington Park's scale — its 11a band and its no killing freeze on record. Your yard writes its own version of Washington Park's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
