Yes — Strong Match
blue star creeper (zones 6-8) covers every zone Rhode Island contains (6b-7b), so hardiness is not what limits it anywhere in the state.

When to Plant Blue Star Creeper in Rhode Island
The frost window
Across Rhode Island, the last spring hard freeze (28°F) clears between Mar 27 and Apr 3, and the first fall hard freeze lands between Nov 7 and Nov 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 218-day window you can count on — up to 239 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
Rhode Island runs as cold as USDA zone 6, 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 Rhode Island; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Soil + Drainage Fit
Blue Star Creeper likes near-neutral soil (pH 6.1-7.8). That's the common-ground band across Rhode Island's glacial till and sandy loam — 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 Rhode Island soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Rhode Island site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.

What Else to Consider for Blue Star Creeper in Rhode Island
Zone compatibility tells you about winter cold survival — but Rhode Island growers also need to think about:
Small lot sizes limit garden space in much of the state
Salt spray affects coastal plantings
Rocky glacial soils need clearing
What to actually do about these — and the constraints that apply to every Rhode Island grower, not just blue star creeper — is covered on the Rhode Island growing guide.
Where in Rhode Island Blue Star Creeper Is Zone-Hardy
Blue Star Creeper is rated for USDA zones 6–8. Every one of Rhode Island’s 5 counties sits inside that band — from Kent County at zone 6b to Washington County at zone 7a — 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.
The planting window moves with it. Providence County holds its last hard freeze (28°F) until about Apr 6, while Newport County is clear by Mar 26 — 11 days apart. Set blue star creeper 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". Blue Star Creeper’s zone 6–8 band: Not verified. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Blue Star Creeper draws native bees (low value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, blue star creeper can only work that bloom inside Rhode Island's frost window — roughly 225 days, opening after the last 28°F freeze (Mar 27 - Apr 3) and closing at the first (Nov 7 - Nov 21), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.
Rhode Island Cooperative Extension
For Rhode Island-specific cultivar recommendations, planting calendars, and pest pressure for blue star creeper, the canonical source is URI Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Blue Star Creeper native to Rhode Island?
No — the USDA PLANTS Database lists Blue Star Creeper as introduced rather than native in the Lower 48, so it is not part of Rhode Island's native flora. It grows here as a garden plant; pairing it with a few Rhode Island natives keeps local pollinators fed too.
Looking for plants that belong here? The Rhode Island growing guide lists plants that USDA PLANTS records growing in Rhode Island and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

Common Questions About Growing Blue Star Creeper in Rhode Island
When can I plant Blue Star Creeper in Rhode Island?
Rhode Island's last spring hard freeze (28°F) clears between Mar 27 and Apr 3, and the first fall hard freeze lands between Nov 7 and Nov 21 (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 Rhode Island 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 Rhode Island?
Rhode Island spans USDA hardiness zones 6b-7b (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 Rhode Island site have?
A typical Rhode Island site sees ~225 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 Rhode Island?
No — the USDA PLANTS Database lists Blue Star Creeper as introduced rather than native in the Lower 48, so it is not part of Rhode Island's native flora. It grows here as a garden plant; pairing it with a few Rhode Island natives keeps local pollinators fed too.
How should I amend the soil for Blue Star Creeper in Rhode Island?
Blue Star Creeper prefers pH 6.1-7.8 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That sits in the common-ground band across Rhode Island soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
