Yes — Strong Match
physic nut (zones 10-12) fits entirely within Hawaii's zone range (10a-13a).
Your yard isn't the whole zone.
Hawaii spans zones 10a-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 physic nut against your parcel's actual hardiness, soil, and sun.

Preferred Soil pH

Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Physic Nut wants 365+ frost-free days; a typical Hawaii site sees ~350 (NOAA Climate Normals). That leaves tight; use transplants and pick early-maturing cultivars.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Physic Nut likes near-neutral soil (pH 5-8). That's the common-ground band across Hawaii's volcanic and laterite — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Hawaii site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider
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
Your side of the island decides everything — check your exact spot's rainfall before choosing crops.
Volcanic soil is nutrient-poor in young flows
A soil test shows what young lava ground is missing — compost and targeted amendments close the gap fast.
Invasive species pressure is severe
Source clean plant material and learn the current watch list — your extension office is the authority on what to keep out.
Where in Hawaii Fits Best
Even within Hawaii's zones 10a-13a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for physic nut (USDA PHZM 2023):
Pollinator + Wildlife Value
Physic Nut draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Hawaii Cooperative Extension
For Hawaii-specific cultivar recommendations, planting calendars, and pest pressure for physic nut, the canonical source is UH Mānoa CTAHR Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Physic Nut native to Hawaii?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Physic Nut as native to Hawaii. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Physic Nut in Hawaii
When can I plant Physic Nut in Hawaii?
Hawaii's last spring frost runs none and first fall frost none (NOAA Climate Normals 1991-2020). Time outdoor planting to after the last-frost window for your specific site, and pull from those dates for transplant scheduling.
What hardiness zone is Physic Nut grown in across Hawaii?
Hawaii spans USDA hardiness zones 10a-13a (USDA ARS PHZM 2023). Physic Nut carries a range of zones 10-12, 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 ~350 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Physic Nut needs 365+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Physic Nut native to Hawaii?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Physic Nut as native to Hawaii. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Physic Nut in Hawaii?
Physic Nut prefers pH 5-8 and well (dry spells) drainage (USDA PLANTS Database). 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 Physic Nut actually grow on my specific land in Hawaii?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores physic nut against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
