Conditional — Some Areas
longleaf pine (zones 7-9) reaches only part of Hawaii (8b-13a): zones 8-9 are in range, so where you are in the state decides it.

Your yard isn't the whole zone.
Hawaii spans zones 8b-13a, 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 longleaf pine against your parcel's actual hardiness, soil, and sun.

Hawaii is not one climate
Hawaii’s winter-low ladder runs across 5 counties, from zone 9 in Hawaii County to zone 11.5 in Kalawao County. That is 25°F between the two counties’ average coldest night — the difference between longleaf pine overwintering in the ground and coming under cover.
The middle half of 5 counties runs 10–11.5 zones, with a median of 10 zones — a 2.5-zone span end to end.

Where Longleaf Pine Stands in Hawaii
Longleaf Pine is rated for zones 7–9 — a cold floor USDA puts at 0 to 10°F. No Hawaii 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 Hawaii winters, not about longleaf pine.

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 Longleaf Pine in Hawaii
The frost window
Hawaii has none — the 1991-2020 station record carries no 28°F killing freeze, so there is no last-frost date to plant after and no first-frost date to harvest before (NOAA Regional Climate Centers ACIS station record). The growing season is year-round; what paces planting here is rainfall, heat and elevation, not the calendar.
Establishment timing
As a long-lived plant, longleaf pine can go in any month here. Aim for the start of your wetter season so it establishes on rainfall rather than on irrigation, and give it a year in the ground before judging it.
Frost tenderness
Longleaf Pine is killed by cold below 32°F (FAO ECOCROP), which simply does not bind at low and mid elevation here. It does bind upslope: Hawaii's summit country genuinely freezes, and no station up there carries a long enough daily record for us to date it.
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.
Soil + Drainage Fit
Longleaf Pine likes near-neutral soil (pH 4-6.5). That's the common-ground band across Hawaii's volcanic and laterite — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 4.5 and 5.5 — worth knowing before you decide whether a Hawaii soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Hawaii site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

What Else to Consider for Longleaf Pine in Hawaii
Zone compatibility tells you about winter cold survival — but Hawaii growers also need to think about:
Extreme rainfall variation — desert on one side, rainforest on the other
Volcanic soil is nutrient-poor in young flows
Invasive species pressure is severe
What to actually do about these — and the constraints that apply to every Hawaii grower, not just longleaf pine — is covered on the Hawaii growing guide.
Where in Hawaii Longleaf Pine Is Zone-Hardy
Longleaf Pine is rated for USDA zones 7–9. No single Hawaii county falls inside it: 0 are colder than the plant’s zone 7 floor and 4 are milder than its zone 9 ceiling. A band this narrow straddles the state rather than sitting inside it.
Across those 5 counties Hawaii’s winter-low ladder runs from zone 9a-13a in Hawaii County to zone 11b-12b in Kalawao County — 3.5 USDA zones of spread, which is 35°F between the two counties’ average coldest night of the year. None of that range reaches the band longleaf pine needs, so here the statewide answer really is the answer.

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

Common Questions About Growing Longleaf Pine in Hawaii
When can I plant Longleaf Pine in Hawaii?
Any month — Hawaii records no 28°F killing freeze in the 1991-2020 station record, so there is no last-frost date to wait for and the growing season is year-round (NOAA Regional Climate Centers ACIS station record). Pace planting by rainfall, heat and elevation instead: the summit country does freeze, and no station up there carries a long enough record to date it.
What hardiness zone is Longleaf Pine grown in across Hawaii?
Hawaii spans USDA hardiness zones 8b-13a (USDA ARS PHZM 2023). Longleaf Pine carries a range of zones 7-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Hawaii site have?
A typical Hawaii site sees ~365 frost-free days per year (derived from NOAA Regional Climate Centers ACIS station record, 1991-2020). Longleaf Pine needs 270+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Longleaf Pine native to Hawaii?
Longleaf Pine is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Hawaii. It can still earn a place in a Hawaii garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Longleaf Pine in Hawaii?
Longleaf Pine prefers pH 4-6.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Hawaii soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Longleaf Pine actually grow on my specific land in Hawaii?
