Unlikely — Zone Mismatch
evergreen huckleberry (zones 7-9) does not overlap with Nebraska's zone range (4b-6a). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Evergreen Huckleberry is hardy to zone 7, and the warmest ground in Nebraska is zone 6 — 1 zone short. Planted in open ground it will not survive a Nebraska winter. To grow it here, grow evergreen huckleberry in a container and move it under cover for the coldest weeks, or give it a greenhouse.

When to Plant Evergreen Huckleberry in Nebraska
The frost window
Across Nebraska, the last spring hard freeze (28°F) clears between Apr 12 and Apr 26, and the first fall hard freeze lands between Oct 15 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 172-day window you can count on — up to 192 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
Nebraska runs as cold as USDA zone 4, and no sourced winter-hardiness floor is on record for evergreen huckleberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether evergreen huckleberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Nebraska; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Sioux County, not the statewide average.

Growing Season Fit
The zone check says evergreen huckleberry does not survive a Nebraska winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on Nebraska under protection.
Frost-free days
Evergreen Huckleberry wants 100+ frost-free days; a typical Nebraska site sees ~181 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Evergreen Huckleberry needs ~1500 GDD (base 50°F) to ripen. The state median runs ~2648 GDD (from PRISM 1991-2020 climate normals), so Nebraska's typical season clears that easily.
Chill hours
Evergreen Huckleberry requires ~600 chill hours (32-45°F dormancy window). Nebraska typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Evergreen Huckleberry tolerates a wide pH range (pH 2.8-6.6) — 3.8 units, acid ground through alkaline — so soil acidity is rarely what limits it in Nebraska. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 4.2 and 5.2 — worth knowing before you decide whether a Nebraska soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Nebraska site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Nebraska's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Evergreen Huckleberry needs about 7 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how evergreen huckleberry performs.

What Else to Consider for Evergreen Huckleberry in Nebraska
Zone compatibility tells you about winter cold survival — but Nebraska growers also need to think about:
Low western rainfall (15 inches) requires irrigation
Extreme wind exposure on open plains
Hail damage during severe storm season
Growing evergreen huckleberry here specifically
At ~1095 days to harvest, evergreen huckleberry barely fits Nebraska's ~181 frost-free days — there's little slack if spring runs cold.

What to actually do about these — and the constraints that apply to every Nebraska grower, not just evergreen huckleberry — is covered on the Nebraska growing guide.
Timing shifts within Nebraska
Nebraska isn't one climate. In Sioux County, the last hard freeze (28°F) holds until about May 14 — roughly 25 days later than the recorded state median — so plant evergreen huckleberry to your county's window, not the statewide date.
Evergreen Huckleberry needs about 100 days of frost-free season to complete its cycle. Even Sioux County — Nebraska’s shortest season at 134 frost-free days — clears that by 34 days, so season length isn’t the constraint anywhere in Nebraska. What varies is your own parcel.
Across Nebraska’s 93 counties the frost-free season runs from 134 days in Sioux County to 207 days in Sarpy County — a spread of 73 days, which is why a single statewide planting date misleads. The median Nebraska county sees 181 frost-free days, leaving evergreen huckleberry about 81 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"). Evergreen Huckleberry's 100-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
Evergreen Huckleberry draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, evergreen huckleberry can only work that bloom inside Nebraska's frost window — roughly 181 days, opening after the last 28°F freeze (Apr 12 - Apr 26) and closing at the first (Oct 15 - Oct 21), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Evergreen Huckleberry in Nebraska
When can I plant Evergreen Huckleberry in Nebraska?
Nebraska's last spring hard freeze (28°F) clears between Apr 12 and Apr 26, and the first fall hard freeze lands between Oct 15 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Evergreen Huckleberry, so this page does not state whether it overwinters in Nebraska 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 Evergreen Huckleberry grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Evergreen Huckleberry carries a range of zones 7-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Nebraska site have?
A typical Nebraska site sees ~181 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Evergreen Huckleberry needs 100+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Sioux, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Evergreen Huckleberry native to Nebraska?
Evergreen Huckleberry is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Nebraska. It can still earn a place in a Nebraska garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Evergreen Huckleberry in Nebraska?
Evergreen Huckleberry tolerates pH 2.8-6.6 and well (dry spells) drainage (FAO ECOCROP). That is a 3.8-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Nebraska site — amend for drainage and organic matter first.
