Yes — Strong Match
sedum (zones 4-9) covers every zone Missouri contains (5b-8a), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Missouri spans zones 5b-8a, 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 sedum against your parcel's actual hardiness, soil, and sun.

When to Plant Sedum in Missouri
The frost window
Across Missouri, the last spring hard freeze (28°F) clears between Mar 27 and Apr 2, and the first fall hard freeze lands between Oct 31 and Nov 7 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 212-day window you can count on — up to 225 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Missouri runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for sedum, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether sedum is a permanent planting or a replant-every-spring crop for you turns on your own zone within Missouri; check its hardiness range against that before treating it as long-lived ground.
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.
Soil + Drainage Fit
Sedum likes near-neutral soil (pH 6-7.5). That's the common-ground band across Missouri's silt loam and clay loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6.5 and 7 — worth knowing before you decide whether a Missouri soil test result is a problem or just a number. 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.

What Else to Consider for Sedum in Missouri
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
Heavy clay soils in many regions
Ozark soils are thin and rocky
What to actually do about these — and the constraints that apply to every Missouri grower, not just sedum — is covered on the Missouri growing guide.
Where in Missouri Sedum Is Zone-Hardy
Sedum is rated for USDA zones 4–9. Every one of Missouri’s 115 counties sits inside that band — from Atchison County at zone 5b to Pemiscot County at zone 7b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 115 counties Missouri’s winter-low ladder runs from zone 5b in Atchison County to zone 7b in Pemiscot County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Crawford County holds its last hard freeze (28°F) until about Apr 10, while Pemiscot County is clear by Mar 9 — 32 days apart. Set sedum out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Sedum’s zone 4–9 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Where in Missouri Fits Best
Even within Missouri's zones 5b-8a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for sedum (USDA PHZM 2023):
Pollinator + Wildlife Value
Sedum draws honeybees, native bees, and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, sedum can only work that bloom inside Missouri's frost window — roughly 219 days, opening after the last 28°F freeze (Mar 27 - Apr 2) and closing at the first (Oct 31 - Nov 7), per NOAA Regional Climate Centers ACIS, 1991-2020.
Missouri Cooperative Extension
For Missouri-specific cultivar recommendations, planting calendars, and pest pressure for sedum, the canonical source is MU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Sedum native to Missouri?
No — the USDA PLANTS Database lists Sedum 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 Sedum in Missouri
When can I plant Sedum in Missouri?
Missouri's last spring hard freeze (28°F) clears between Mar 27 and Apr 2, and the first fall hard freeze lands between Oct 31 and Nov 7 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Sedum, so this page does not state whether it overwinters in Missouri and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Sedum grown in across Missouri?
Missouri spans USDA hardiness zones 5b-8a (USDA ARS PHZM 2023). Sedum carries a range of zones 4-9, 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 ~219 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Sedum 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.
Is Sedum native to Missouri?
No — the USDA PLANTS Database lists Sedum 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 Sedum in Missouri?
Sedum prefers pH 6-7.5 and well (dry spells) drainage (Growable Ground Plant 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.
Will Sedum actually grow on my specific land in Missouri?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores sedum against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
