University, Florida, sits in USDA hardiness zone 10a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Crops well matched to these conditions include okra, meyer lemon, california poppy, and artichoke — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in University, 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 University lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

Every figure names the dataset it came from. No 30-year normal resolves at this town’s own centroid, so the hard-freeze dates are Orange County’s — the closest measured record, labelled as such rather than passed off as local.

What this means for growing in University
Each reading below is measured for University itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsUniversity runs about 335 days between hard freezes (read from Orange County, the closest normal to University) — 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
MeasuredUniversity 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.
USDA PHZM 2023
The kind of country University is in
University sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at University's own centroid rather than borrowed from Orange County.

Is it too late to plant in University?
Usually not — gardeners here simply switch what goes in the ground as the season moves. 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 20 (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.

Your land is one point inside University
Everything above resolves to University as a whole — one PHZM band, read across 6K acres, with hard-freeze dates borrowed from Orange County’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 University
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 Orange County’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 University
When does frost risk typically end in University?
The last hard freeze (28°F) in University typically lands around Jan 20, 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 10.
When is the first frost in University?
The first hard freeze (28°F) in University 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 335 days after the spring freeze cleared.
How long is the growing season in University?
Measured between 28°F hard freezes, University sees about 335 frost-free days — roughly Jan 20 through Dec 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 10 to Dec 7, about 300 days.
Is the soil safe to grow vegetables in University?
The federal record around University is a meaningful one — 1,100 documented sites, mostly Underground Storage Tanks entries (585), the nearest Underground Storage Tanks record about 0.1 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 University?
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.
