one one (zones 10-12) partially overlaps with Florida (8a-11b). It can grow in zones 10-11 within the state.
Your yard isn't the whole zone.
Florida spans zones 8a-11b, 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 one one against your parcel's actual hardiness, soil, and sun.

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
One One wants 365+ frost-free days; a typical Florida site sees ~320 (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
One One likes near-neutral soil (pH 5-7). That's the common-ground band across Florida's sandy and muck (everglades) — a soil test confirms it for your site. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.

What Else to Consider
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
Build organic matter relentlessly — compost and cover crops turn sand into soil that holds both water and food.
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Space plants for airflow, water at the base in the morning, and choose resistant varieties — your extension office lists the proven ones.
Hurricane season (June-November) can destroy plantings
Favor wind-tough perennials, stake young trees properly, and keep fall crops in containers you can move ahead of a storm.
Nematodes are a serious pest in sandy FL soils
Summer solarization and crop-family rotation knock nematodes back — your extension office can confirm the species from a soil sample.

Common Questions About Growing One One in Florida
When can I plant One One in Florida?
Florida's last spring frost runs jan 1 - mar 15 and first fall frost nov 15 - never (south fl) (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 One One grown in across Florida?
Florida spans USDA hardiness zones 8a-11b (USDA ARS PHZM 2023). One One 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 Florida site have?
A typical Florida site sees ~320 frost-free days per year (derived from NOAA Climate Normals 1991-2020). One One needs 365+ frost-free days, 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 One One in Florida?
One One prefers pH 5-7 and poorly (saturated >50% of year) drainage (USDA PLANTS Database). That sits in the common-ground band across Florida soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will One One actually grow on my specific land in Florida?
