Conditional — Some Areas
camellia (zones 7-9) has limited zone overlap with Missouri (5b-7a). Only zones 7-7 in the state are suitable.
Your yard isn't the whole zone.
Missouri spans zones 5b-7a, 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 camellia against your parcel's actual hardiness, soil, and sun.

When to Plant Camellia in Missouri
The frost window
Across Missouri, the last spring frost clears between Apr 5 and Apr 25, and the first fall frost lands between Oct 5 and Oct 30 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 163-day window you can count on — up to 208 days on a mild site in a kind year.
Frost tenderness
Camellia is frost-tender — its listed minimum temperature is 46.4°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Establishment timing
As a long-lived plant, camellia isn't racing the calendar to a harvest date. Plant it in spring once the last-frost window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
Timing tuned to sub-state frost dates — Putnam County, not the statewide average.
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
Camellia wants 240+ frost-free days; a typical Missouri site sees ~190 (NOAA Climate Normals). That leaves tight; use transplants and pick early-maturing cultivars.
Chill hours
Camellia requires ~400 chill hours (32-45°F dormancy window). Missouri typically banks ~1050 chill hours per winter (MSU Extension method), which keeps this plant on track.
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
Camellia likes near-neutral soil (pH 4-6). That's the common-ground band across Missouri's silt loam and clay loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Missouri site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Whether camellia thrives in Missouri comes down to drainage, and SSURGO drainage class flips from well-drained to poorly-drained parcel to parcel — your soil map unit, not the state average, is the real answer.

Camellia in Missouri — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 7-9 (USDA PLANTS Database)

- Growing Season: Apr 5 - Apr 25 to Oct 5 - Oct 30 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Missouri growers also need to think about:
Highly variable weather with late frosts and early heat
Let your local frost normals call the plantings — Missouri springs punish the calendar-planters and reward the patient.
Heavy clay soils in many regions
Raised beds solve clay drainage the first weekend — and yearly compost turns the ground under them into loam.
Ozark soils are thin and rocky
One soil test shows what thin Ozark ground actually holds — then build up with compost or beds where the depth runs out.
Growing camellia here specifically
Camellia needs sharp drainage and sends deep roots hardy to about 46°F; in Missouri, about 31.8% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.

Timing shifts within Missouri
Missouri isn't one climate. In Putnam County, the last hard freeze (28°F) holds until about Mar 23 — roughly 13 days later than the recorded state median — so plant camellia to your county's window, not the statewide date.
County last-freeze dates: NOAA/PRISM Climate Normals 1991-2020, 28°F threshold (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Camellia draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Missouri Cooperative Extension
For Missouri-specific cultivar recommendations, planting calendars, and pest pressure for camellia, the canonical source is MU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Camellia native to Missouri?
No — the USDA PLANTS Database lists Camellia as introduced rather than native in the Lower 48, so it is not part of Missouri's native flora. It grows here as a garden plant; pairing it with a few Missouri natives keeps local pollinators fed too.

Common Questions About Growing Camellia in Missouri
When can I plant Camellia in Missouri?
Missouri's last spring frost clears between Apr 5 and Apr 25, and the first fall frost lands between Oct 5 and Oct 30 (NOAA Climate Normals 1991-2020). Camellia is a long-lived planting, so target spring just after your local last frost — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Camellia grown in across Missouri?
Missouri spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Camellia 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 Missouri site have?
A typical Missouri site sees ~190 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Camellia needs 240+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Putnam, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Camellia native to Missouri?
No — the USDA PLANTS Database lists Camellia as introduced rather than native in the Lower 48, so it is not part of Missouri's native flora. It grows here as a garden plant; pairing it with a few Missouri natives keeps local pollinators fed too.
How should I amend the soil for Camellia in Missouri?
Camellia prefers pH 4-6 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Missouri soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
