Generally — Most Areas
lima bean (zones 3-11) partially overlaps with California (5a-11a). It can grow in zones 5-11 within the state.
Your yard isn't the whole zone.
California spans zones 5a-11a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score lima bean against your land's actual soil, sun, and frost.

When to Plant Lima Bean in California
The frost window
Across California, the last spring frost clears between Jan 15 and May 15, and the first fall frost lands between Oct 1 and Dec 31 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 139-day window you can count on — up to 350 days on a mild site in a kind year.
Frost tenderness
Lima Bean is frost-tender — its listed minimum temperature is 55.4°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Days to maturity vs. the window
At 75 days to maturity (USDA PLANTS Database), a planting right after last frost ripens with 64 days to spare even in California's tightest frost scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
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
Lima Bean wants 60+ frost-free days; a typical California site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Lima Bean needs ~1800 GDD (base 50°F) to ripen. The state median runs ~3850 GDD (USDA NRCS county aggregates), so California's typical season clears that easily.
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
Lima Bean likes near-neutral soil (pH 4.5-8.4). That's the common-ground band across California's alluvial clay and sandy loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your California 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 California growers also need to think about:
Drought is a persistent challenge — irrigation is essential in most regions
Design the water system before the plants: drip lines plus a thick mulch layer run a full garden on surprisingly little water.
Wildfire risk affects rural and foothill properties
Keep plantings low, lean, and well-watered near structures — your extension office publishes firewise landscaping guides for your county.
Adobe clay soils in valleys drain poorly without amendment
Work in compost over seasons, or skip the fight with a raised bed — adobe's nutrients are excellent once drainage is solved.
Wide climate variation means plant selection is highly location-specific
Zones run 5a to 11a in one state — check your exact zone before trusting any statewide planting list.
Pollinator + Wildlife Value
Lima Bean draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
California Cooperative Extension
For California-specific cultivar recommendations, planting calendars, and pest pressure for lima bean, the canonical source is UC Agriculture and Natural Resources. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Lima Bean native to California?
No — the USDA PLANTS Database lists Lima Bean as introduced rather than native in the Lower 48, so it is not part of California's native flora. It grows here as a garden plant; pairing it with a few California natives keeps local pollinators fed too.

Common Questions About Growing Lima Bean in California
When can I plant Lima Bean in California?
California's last spring frost clears between Jan 15 and May 15, and the first fall frost lands between Oct 1 and Dec 31 (NOAA Climate Normals 1991-2020). Lima Bean is frost-tender — its listed minimum temperature is 55.4°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
Can Lima Bean mature before first frost in California?
Yes — Lima Bean matures in 75 days (USDA PLANTS Database), and California's dependable frost-free window runs 139 days (NOAA Climate Normals 1991-2020), leaving 64 days of margin. Plant just after last frost and it ripens ahead of the first fall frost.
What hardiness zone is Lima Bean grown in across California?
California spans USDA hardiness zones 5a-11a (USDA ARS PHZM 2023). Lima Bean carries a range of zones 3-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical California site have?
A typical California site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Lima Bean needs 60+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Lima Bean native to California?
No — the USDA PLANTS Database lists Lima Bean as introduced rather than native in the Lower 48, so it is not part of California's native flora. It grows here as a garden plant; pairing it with a few California natives keeps local pollinators fed too.
How should I amend the soil for Lima Bean in California?
Lima Bean prefers pH 4.5-8.4 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across California soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
