Not Verified — Winters This Mild
Not verified for winters this mild: beach plum is listed for zones 3-7 — a growing recommendation, not a heat limit — and we hold no heat rating for it. Florida runs zones 8b-12a, milder than that range, so this page gives no verdict here. The frost window and season figures below are measured for Florida.

Your yard isn't the whole zone.
Florida spans zones 8b-12a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score beach plum against your parcel's actual hardiness, soil, and sun.

Florida is not one climate
Florida’s winter-low ladder runs across 67 counties, from zone 8.5 in Holmes County to zone 10.5 in Palm Beach County. That is 20°F between the two counties’ average coldest night — the difference between beach plum overwintering in the ground and coming under cover.
The middle half of 67 counties runs 9–10 zones, with a median of 9.5 zones — a 2-zone span end to end.

Where Beach Plum Stands in Florida
Beach Plum is rated for zones 3–7 — a cold floor USDA puts at -40 to -30°F. No Florida county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Florida winters, not about beach plum.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Beach Plum in Florida
The frost window
Across Florida, the last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 300-day window you can count on — up to 327 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Florida runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for beach plum, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether beach plum is a permanent planting or a replant-every-spring crop for you turns on your own zone within Florida; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Chill hours
Beach Plum requires ~800 chill hours (32-45°F dormancy window). Florida typically banks ~0 chill hours per winter, short of this plant's requirement — fruit set may suffer in mild years without a low-chill cultivar.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Beach Plum tolerates a wide pH range (pH 4.5-7.5) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Florida. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 6.3 — worth knowing before you decide whether a Florida soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Florida site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.

What Else to Consider for Beach Plum in Florida
Zone compatibility tells you about winter cold survival — but Florida growers also need to think about:
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Hurricane season (June-November) can destroy plantings
Nematodes are a serious pest in sandy FL soils
What to actually do about these — and the constraints that apply to every Florida grower, not just beach plum — is covered on the Florida growing guide.
Where in Florida Beach Plum's Listed Zones Fall
Beach Plum is rated for USDA zones 3–7. Every Florida county sits above it. Even Holmes County, the state’s coldest at zone 8b, is milder than the plant’s zone 7 ceiling — the constraint here is winter chill it will not get, not cold it cannot take.
Across those 67 counties Florida’s winter-low ladder runs from zone 8b in Holmes County to zone 10b in Palm Beach County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. None of that range reaches the band beach plum needs, so here the statewide answer really is the answer.

Pollinator + Wildlife Value
Beach Plum draws honeybees, native bees, and butterflies (high value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, beach plum can only work that bloom inside Florida's frost window — roughly 320 days, opening after the last 28°F freeze (Jan 25 - Feb 10) and closing at the first (Dec 7 - Dec 18), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Is Beach Plum native to Florida?
Beach Plum is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Florida. It can still earn a place in a Florida garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Beach Plum in Florida
When can I plant Beach Plum in Florida?
Florida's last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Beach Plum, so this page does not state whether it overwinters in Florida and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Beach Plum grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Beach Plum is listed for zones 3-7, which do not overlap them, so there is no zone in Florida where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
How many frost-free days does a typical Florida site have?
A typical Florida site sees ~320 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Beach Plum needs 240+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Beach Plum native to Florida?
Beach Plum is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Florida. It can still earn a place in a Florida garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Beach Plum in Florida?
Beach Plum tolerates pH 4.5-7.5 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Florida site — amend for drainage and organic matter first.
Will Beach Plum actually grow on my specific land in Florida?
