Unlikely — Zone Mismatch
canna lily (zones 7-11) does not overlap with Nebraska's zone range (4b-6a). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Canna Lily 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 canna lily in a hoop house or unheated greenhouse — its modeled 1.5-zone lift covers this gap.

Nebraska is not one climate
A single Nebraska answer averages 93 counties whose growing seasons are 73 days apart — from 134 frost-free days in Sioux County to 207 in Sarpy County. Which end of that your land sits nearer changes what canna lily can finish before the first hard freeze.
The middle half of 93 counties runs 173–191 days, with a median of 181 days — a 73-day span end to end.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Canna Lily Stands in Nebraska
Canna Lily is rated for zones 7–11 — a cold floor USDA puts at 0 to 10°F. No Nebraska county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Nebraska winters, not about canna lily.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Canna Lily 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.
When to start the seed
Those dates are when canna lily goes out, not when it starts. It is sown under cover about 8 weeks ahead, so counting back from Nebraska's late-side last freeze of Apr 26 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Timing tuned to sub-state frost dates — Sioux 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
Canna Lily tolerates a wide pH range (pH 5-8) — 3 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 5.5 and 7.5 — 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. Canna Lily needs about 59 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 canna lily performs.

What Else to Consider for Canna Lily 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 canna lily here specifically
Canna Lily wants pH 5.0–8.0 and rates to USDA zones 7–11, but Nebraska's soils are dominantly silt loam — the fit is decided by your parcel's own map unit, not the state average.
Match canna lily to your parcel's SSURGO map unit — test pH and texture, and amend toward its 5.0–8.0 range. How to handle it →
What to actually do about these — and the constraints that apply to every Nebraska grower, not just canna lily — 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 canna lily 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 Nebraska Canna Lily Is Zone-Hardy
Canna Lily is rated for USDA zones 7–11. No Nebraska county reaches it. Even Thayer County, the state’s mildest winter at zone 6a, sits below the plant’s zone 7 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 93 counties Nebraska’s winter-low ladder runs from zone 4b in Sioux County to zone 6a in Thayer 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 canna lily needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Canna Lily’s zone 7–11 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
Canna Lily draws hummingbirds and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, canna lily 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.
Recommended Canna Lily Varieties for Nebraska
Nebraska publishes no state variety trial for canna lily, so we won't invent a "best for Nebraska" list. Choose types rated to your USDA hardiness zone (4b-6a), and confirm winter survival and drainage against your own parcel.

Common Questions About Growing Canna Lily in Nebraska
When can I plant Canna Lily 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
What hardiness zone is Canna Lily grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Canna Lily carries a range of zones 7-11, 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). Canna Lily should be matched against that window, 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.
How should I amend the soil for Canna Lily in Nebraska?
Canna Lily tolerates pH 5-8 and well (dry spells) drainage (FAO ECOCROP). That is a 3-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.
Will Canna Lily actually grow on my specific land in Nebraska?
