Can I Grow Blue Star Creeper in Minnesota?

Blue Star Creeper in Minnesota — the short answer

Minnesota is not one climate

Where Blue Star Creeper Stands in Minnesota

Zone Comparison

Plant data: Growable Ground Plant Database, compiled from FAO ECOCROP, USDA PLANTS, and university Extension sources — per-field provenance varies and is published with the dataset. State data: USDA ARS PHZM 2023, NOAA Climate Normals, NRCS SSURGO.

When to Plant Blue Star Creeper in Minnesota

Timing tuned to sub-state frost dates — Lake County, not the statewide average.

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 Minnesota's prairie loam and clay — 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 Minnesota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Minnesota 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 Minnesota

Zone compatibility tells you about winter cold survival — but Minnesota growers also need to think about:

What to actually do about these — and the constraints that apply to every Minnesota grower, not just blue star creeper — is covered on the Minnesota growing guide.

Timing shifts within Minnesota

Minnesota isn't one climate. In Lake County, the last hard freeze (28°F) holds until about May 14 — roughly 23 days later than the recorded state median — so plant blue star creeper to your county's window, not the statewide date.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.

Where in Minnesota Blue Star Creeper Is Zone-Hardy

Blue Star Creeper is rated for USDA zones 6–8. No Minnesota county reaches it. Even Watonwan County, the state’s mildest winter at zone 5a, sits below the plant’s zone 6 floor — so in open ground this one needs winter protection here, or a container that comes under cover.

Across those 87 counties Minnesota’s winter-low ladder runs from zone 3b in Beltrami County to zone 5a in Watonwan County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. None of that range reaches the band blue star creeper needs, so here the statewide answer really is the answer.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. 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 Minnesota's frost window — roughly 174 days, opening after the last 28°F freeze (Apr 19 - Apr 30) and closing at the first (Oct 10 - Oct 17), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Minnesota Cooperative Extension

For Minnesota-specific cultivar recommendations, planting calendars, and pest pressure for blue star creeper, the canonical source is University of Minnesota Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Blue Star Creeper native to Minnesota?

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

Looking for plants that belong here? The Minnesota growing guide lists plants that USDA PLANTS records growing in Minnesota 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.
