Conditional — Some Areas
green-and-gold (zones 5-8) has limited zone overlap with Wyoming (3a-5b). Only zones 5-5 in the state are suitable.
Your yard isn't the whole zone.
Wyoming spans zones 3a-5b, 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 green and gold against your parcel's actual hardiness, soil, and sun.

When to Plant Green And Gold in Wyoming
The frost window
Across Wyoming, the last spring frost clears between May 10 and Jun 15, and the first fall frost lands between Aug 25 and Sep 25 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 71-day window you can count on — up to 138 days on a mild site in a kind year.
Establishment timing
As a long-lived plant, green and gold isn't racing the calendar to a harvest date. Plant it in spring once the last-frost window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
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
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Green And Gold wants 120+ frost-free days; a typical Wyoming site sees ~170 (NOAA Climate Normals). That leaves a workable window — start indoors to bank time.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Green And Gold likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Wyoming's sandy loam and clay — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Wyoming site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Green And Gold in Wyoming — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 5-8 (USDA PLANTS Database)
- State Zones: 3a-5b (USDA ARS PHZM 2023)
- Growing Season: May 10 - Jun 15 to Aug 25 - Sep 25 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Wyoming growers also need to think about:
Extremely short growing season (60-90 frost-free days)
At 60-90 frost-free days, a greenhouse or high tunnel isn't optional equipment — it's where the season actually happens.
Very low rainfall requires irrigation
Drip irrigation under mulch makes scarce water go the distance — build the system before the first bed.
Persistent high winds desiccate and damage plants
Windbreaks first, plants second — a sheltered bed loses a fraction of the moisture an exposed one does.
Pollinator + Wildlife Value
Green And Gold draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Wyoming Cooperative Extension
For Wyoming-specific cultivar recommendations, planting calendars, and pest pressure for green and gold, the canonical source is University of Wyoming Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Green And Gold native to Wyoming?
Green And Gold is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Wyoming. It can still earn a place in a Wyoming garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Green And Gold in Wyoming
When can I plant Green And Gold in Wyoming?
Wyoming's last spring frost clears between May 10 and Jun 15, and the first fall frost lands between Aug 25 and Sep 25 (NOAA Climate Normals 1991-2020). Green And Gold is a long-lived planting, so target spring just after your local last frost — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Green And Gold grown in across Wyoming?
Wyoming spans USDA hardiness zones 3a-5b (USDA ARS PHZM 2023). Green And Gold carries a range of zones 5-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Wyoming site have?
A typical Wyoming site sees ~170 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Green And Gold 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 Green And Gold native to Wyoming?
Green And Gold is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Wyoming. It can still earn a place in a Wyoming garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Green And Gold in Wyoming?
Green And Gold prefers pH 5.5-7.5 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Wyoming soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Green And Gold actually grow on my specific land in Wyoming?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores green and gold against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
