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 arizona sycamore 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 arizona sycamore 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.
Measured across 5 Hawaii counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.

When to Plant Arizona Sycamore 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, arizona sycamore 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 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
Arizona Sycamore likes near-neutral soil (pH 5.8-7.5). That's the common-ground band across Hawaii's volcanic and laterite — a soil test confirms it for your site.

What Else to Consider for Arizona Sycamore 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 arizona sycamore — is covered on the Hawaii growing guide.

Common Questions About Growing Arizona Sycamore in Hawaii
When can I plant Arizona Sycamore 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 Arizona Sycamore grown in across Hawaii?
Hawaii spans USDA hardiness zones 8b-13a (USDA ARS PHZM 2023). Arizona Sycamore carries a range of zones Data pending, 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). Arizona Sycamore should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Arizona Sycamore in Hawaii?
Arizona Sycamore prefers pH 5.8-7.5 (USDA PLANTS). 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 Arizona Sycamore actually grow on my specific land in Hawaii?
