Can I Grow Heliconia in Wyoming?

Heliconia in Wyoming — the short answer

Wyoming is not one climate

Where Heliconia Stands in Wyoming

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 Heliconia in Wyoming

Timing tuned to sub-state frost dates — Teton 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.

What Else to Consider for Heliconia in Wyoming

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

What to actually do about these — and the constraints that apply to every Wyoming grower, not just heliconia — is covered on the Wyoming growing guide.

Timing shifts within Wyoming

Wyoming isn't one climate. In Teton County, the last hard freeze (28°F) holds until about Jun 16 — roughly 41 days later than the recorded state median — so plant heliconia 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 Wyoming Heliconia Is Zone-Hardy

Heliconia is rated for USDA zones 8–10. No Wyoming county reaches it. Even Uinta County, the state’s mildest winter at zone 5b, sits below the plant’s zone 8 floor — so in open ground this one needs winter protection here, or a container that comes under cover.

Across those 23 counties Wyoming’s winter-low ladder runs from zone 4b in Albany County to zone 5b in Uinta County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. None of that range reaches the band heliconia needs, so here the statewide answer really is the answer.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Heliconia’s zone 8–10 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Heliconia draws hummingbirds (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, heliconia can only work that bloom inside Wyoming's frost window — roughly 151 days, opening after the last 28°F freeze (May 4 - May 13) and closing at the first (Sep 30 - Oct 7), per NOAA Regional Climate Centers ACIS, 1991-2020.

Recommended Heliconia Varieties for Wyoming

Wyoming publishes no state variety trial for heliconia, so we won't invent a "best for Wyoming" list. Choose types rated to your USDA hardiness zone (3b-6a), and confirm winter survival and drainage against your own parcel.

Wyoming Cooperative Extension

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