La Verne, California, sits in USDA hardiness zone 10a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Growers here do well with artichoke, meyer lemon, california poppy, and cabbage — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in La Verne, 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 La Verne lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

La Verne — the short answer
La Verne, California: USDA zone 10a, no 28°F killing freeze on record — the season is year-round, across 5K acres of city.

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 La Verne
Each reading below is measured for La Verne itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredLa Verne 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 La Verne is in
La Verne sits in the Southern California/Northern Baja Coast — EPA Level III, inside the wider Mediterranean California. That is read at La Verne's own centroid rather than borrowed from Los Angeles County.

What an experienced grower watches for around here
In and around La Verne, Brownfields runs higher than the national average — 5,347 sites within ~10 miles of La Verne. That's not a problem with your land — it's information about it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside La Verne
Everything above resolves to La Verne as a whole — one PHZM band and one 28°F frost record, read across 5K 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 La Verne
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 La Verne
Is it too late to plant in La Verne?
No — La Verne 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 La Verne?
It doesn't — La Verne 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 La Verne?
Year-round — the 1991–2020 station record for La Verne 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 La Verne?
The federal record around La Verne runs heavier than most — 5,919 documented sites, mostly Brownfields entries (5,347), the nearest Brownfields record under a tenth of a mile 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 La Verne's scale — its 10a band and its no killing freeze on record. Your yard writes its own version of La Verne's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
