Conditional — Some Areas
Barbados flowerfence (zones 8-11) reaches only part of Missouri (5b-8a): zone 8 are in range, so where you are in the state decides it.
One zone short — what would close it
Barbados Flowerfence is hardy to zone 8, and the warmest ground in Missouri is zone 7 — 1 zone short. Planted in open ground it will not survive a Missouri winter. To grow it here, grow barbados flowerfence in a container and move it under cover for the coldest weeks, or give it a greenhouse.
Season extension and overwintering under cover both work at this margin. How to buy the weeks →

When to Plant Barbados Flowerfence 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 barbados flowerfence, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether barbados flowerfence 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.
Timing tuned to sub-state frost dates — Crawford 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
The zone check says barbados flowerfence survives winter in part of Missouri, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Barbados Flowerfence wants 120+ frost-free days; a typical Missouri site sees ~219 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Barbados Flowerfence likes near-neutral soil (pH 6-8.5). 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 7.5 — 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), excessive (dry/moderately dry). 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
SSURGO maps about 31.8% of Missouri as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Barbados Flowerfence sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

- Plant Zones: 8-11 (USDA PLANTS Database)
- State Zones: 5b-8a (USDA ARS PHZM 2023)

What Else to Consider for Barbados Flowerfence 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
Growing barbados flowerfence here specifically
Barbados Flowerfence roots run medium and prefer pH 6.0–8.5, but drainage comes first here: SSURGO maps about 31.8% of Missouri as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant barbados flowerfence on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Missouri grower, not just barbados flowerfence — is covered on the Missouri growing guide.
Timing shifts within Missouri
Missouri isn't one climate. In Crawford County, the last hard freeze (28°F) holds until about Apr 10 — roughly 12 days later than the recorded state median — so plant barbados flowerfence to your county's window, not the statewide date.
Barbados Flowerfence needs about 120 days of frost-free season to complete its cycle. Even Crawford County — Missouri’s shortest season at 192 frost-free days — clears that by 72 days, so season length isn’t the constraint anywhere in Missouri. What varies is your own parcel.
Across Missouri’s 115 counties the frost-free season runs from 192 days in Crawford County to 258 days in Pemiscot County — a spread of 66 days, which is why a single statewide planting date misleads. The median Missouri county sees 219 frost-free days, leaving barbados flowerfence about 99 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Barbados Flowerfence's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Barbados Flowerfence draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, barbados flowerfence 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.

Is Barbados Flowerfence native to Missouri?
Barbados Flowerfence is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Missouri. It can still earn a place in a Missouri garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Barbados Flowerfence in Missouri
When can I plant Barbados Flowerfence 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 Barbados Flowerfence, 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 Barbados Flowerfence grown in across Missouri?
Missouri spans USDA hardiness zones 5b-8a (USDA ARS PHZM 2023). Barbados Flowerfence carries a range of zones 8-11, 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). Barbados Flowerfence needs 120+ 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 Crawford, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Barbados Flowerfence native to Missouri?
Barbados Flowerfence is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Missouri. It can still earn a place in a Missouri garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Barbados Flowerfence in Missouri?
Barbados Flowerfence prefers pH 6-8.5 and well (dry spells), excessive (dry/moderately dry) drainage (FAO ECOCROP). 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.
