Conditional — Some Areas
blue star creeper (zones 6-8) reaches only part of Louisiana (8b-10b): zone 8 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Louisiana spans zones 8b-10b, 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 blue star creeper against your parcel's actual hardiness, soil, and sun.

When to Plant Blue Star Creeper in Louisiana
The frost window
Across Louisiana, the last spring hard freeze (28°F) clears between Jan 30 and Feb 17, and the first fall hard freeze lands between Nov 30 and Dec 8 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 286-day window you can count on — up to 312 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
Louisiana runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for blue star creeper, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether blue star creeper is a permanent planting or a replant-every-spring crop for you turns on your own zone within Louisiana; 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.
Growing Season Fit
The zone check says blue star creeper survives winter in part of Louisiana, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Blue Star Creeper wants 120+ frost-free days; a typical Louisiana site sees ~298 (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
Blue Star Creeper likes near-neutral soil (pH 6.1-7.8). That's the common-ground band across Louisiana's alluvial clay and muck — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6.1 and 7 — worth knowing before you decide whether a Louisiana soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Louisiana site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Blue Star Creeper in Louisiana
Zone compatibility tells you about winter cold survival — but Louisiana growers also need to think about:
Extreme humidity and rainfall promote rot and fungal diseases
Poor drainage in delta and coastal areas
Hurricane damage risk from June through November
What to actually do about these — and the constraints that apply to every Louisiana grower, not just blue star creeper — is covered on the Louisiana growing guide.
Timing shifts within Louisiana
Blue Star Creeper needs about 120 days of frost-free season to complete its cycle. Even Claiborne County — Louisiana’s shortest season at 265 frost-free days — clears that by 145 days, so season length isn’t the constraint anywhere in Louisiana. What varies is your own parcel.
Across Louisiana’s 64 counties the frost-free season runs from 265 days in Claiborne County to 365 days in Plaquemines County — a spread of 100 days, which is why a single statewide planting date misleads. The median Louisiana county sees 298 frost-free days, leaving blue star creeper about 178 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"). Blue Star Creeper'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
Blue Star Creeper draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, blue star creeper can only work that bloom inside Louisiana's frost window — roughly 298 days, opening after the last 28°F freeze (Jan 30 - Feb 17) and closing at the first (Nov 30 - Dec 8), per NOAA Regional Climate Centers ACIS, 1991-2020.

Is Blue Star Creeper native to Louisiana?
No — the USDA PLANTS Database lists Blue Star Creeper as introduced rather than native in the Lower 48, so it is not part of Louisiana's native flora. It grows here as a garden plant; pairing it with a few Louisiana natives keeps local pollinators fed too.

Common Questions About Growing Blue Star Creeper in Louisiana
When can I plant Blue Star Creeper in Louisiana?
Louisiana's last spring hard freeze (28°F) clears between Jan 30 and Feb 17, and the first fall hard freeze lands between Nov 30 and Dec 8 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Blue Star Creeper, so this page does not state whether it overwinters in Louisiana 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 Blue Star Creeper grown in across Louisiana?
Louisiana spans USDA hardiness zones 8b-10b (USDA ARS PHZM 2023). Blue Star Creeper carries a range of zones 6-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Louisiana site have?
A typical Louisiana site sees ~298 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Blue Star Creeper needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Blue Star Creeper native to Louisiana?
No — the USDA PLANTS Database lists Blue Star Creeper as introduced rather than native in the Lower 48, so it is not part of Louisiana's native flora. It grows here as a garden plant; pairing it with a few Louisiana natives keeps local pollinators fed too.
How should I amend the soil for Blue Star Creeper in Louisiana?
Blue Star Creeper prefers pH 6.1-7.8 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Louisiana soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
