Planting zones in Las Vegas-Henderson-North Las Vegas, NV
This metro spans USDA zones 8a to 9b, so there is no single zone for Las Vegas-Henderson-North Las Vegas, NV and anyone who gives you one is rounding. 49% of its ZIP codes are zone 9a; the rest are not.

Las Vegas-Henderson-North Las Vegas, NV does not have one planting answer
Its own weather stations disagree about 14 of the 32 crops in this table right now, so any single list would be wrong for part of the metro area. That is not a gap in the data — it is what the data says.
- Shortest season
- 124 days
MT CHARLESTON FIRE STN, NV US (USC00265400) - Longest season
- 356 days
BULLHEAD CITY, AZ US (USC00021050)
232 days of growing season separate those two stations, and both serve ZIP codes in Las Vegas-Henderson-North Las Vegas, NV. The ZIP lookup above answers for one address instead of averaging a place that has no average.
Why the hardiness zone does not settle this
A USDA zone is a winter-minimum statistic. It was never a growing-season one, and it does not behave like one: within a single zone the growing season runs a median 54 days wider at the 10th–90th percentile, and annual growing degree days vary by 2.02×.
The zones also overlap rather than stack — 30% of zone 6b freezes before the median zone 6a station. The zone tells you what survives your winter; the station tells you what finishes before your autumn.
All 14 stations agreeAt least one station
Every one of the 14 NOAA stations serving this metro area counts May 31 – October 2 as growing season (124 days). Widening to any single station gives January 4 – December 23 (353 days).
That is a 229-day difference inside one metro area — which is why this page gives ranges rather than a single planting date. The ZIP lookup above resolves it to one station.
Which zone you are in depends where you are
Las Vegas-Henderson-North Las Vegas, NV covers 4 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it — which is fine for the 49% in zone 9a and wrong for the other 51%. Here is the actual split.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 9a | 37 | 49% | |
| 9b | 31 | 41% | |
| 8b | 7 | 9% | |
| 8a | 1 | 1% |
Zones are published per ZIP code, so yours is exact even though the metro's is not. The hardiness tool will tell you which one you are in.
Your freeze dates
Those are the earliest and latest medians among the 14 stations serving this metro — not an average, and not one station standing in for the rest. Half of years freeze later than a station's own median.
The spread is the point. Even in a metro that is one hardiness zone throughout, its stations disagree about the last spring freeze. Hardiness zone and frost date measure different things — a zone is the average annual coldest night, a freeze date is when the season turns — and a place can be uniform in one and varied in the other. Use the tools below with your own ZIP rather than the ends of this range.
Your growing season
NOAA publishes a growing-season length for each station, and across the 14 stations serving Las Vegas-Henderson-North Las Vegas, NV it runs 124–356 days . That figure is published, not computed from the two freeze dates — subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 77–109 °F , at or above the 90 °F point where cool-season crops bolt and tomato and pepper pollen fails — so midsummer sowings of lettuce and its relatives are worth holding here. Summer rain over the same months runs 0.4–4.9" across those 14 stations, against the rough inch a week — about 13 inches over the same 92 days — that a vegetable garden is usually reckoned to want. The middle station covers about 8% of it, so a summer garden here is watered rather than rained on. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 103 °F summer afternoon drying the soil faster than a cool one.
When to start seeds in Las Vegas-Henderson-North Las Vegas, NV
Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 14 stations — the earliest and latest that job falls anywhere in the metro — because no one station speaks for the whole area.

What survives the winter changes across Las Vegas-Henderson-North Las Vegas, NV
Of 74 perennial fruits, nuts, berries, vegetables and herbs, 57 come through the winter in zone 8a and only 40 in zone 9b. That is a different garden at each end of the same metro.
| Zone | ZIPs | Survive | Fail for being too warm |
|---|---|---|---|
| 8a | 1 | 57 of 74 | 8 |
| 8b | 7 | 54 of 74 | 11 |
| 9a | 37 | 46 of 74 | 25 |
| 9b | 31 | 40 of 74 | 32 |
The last column is the counterintuitive one, and it is why the totals do not simply rise as the winters get milder. Most temperate fruit needs a documented number of hours below about 45 °F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the summer heat that comes with it. See the full list with reasons.
At least one station here freezes across the new year, which puts the two ends of a spread on opposite sides of the calendar. Drawing it would produce a bar spanning almost the whole year and meaning nothing, so none is drawn.
The 14 stations behind these numbers
All 14 NOAA stations whose normals this page quotes, spanning about 181 km north to south. Every one is named with its identifier in the station list below — this page does not single one out, because no one station speaks for a whole metro area.
A relative sketch, not a map with a projection: longitude is adjusted for latitude so the shape is not stretched, and there is no basemap. For the one station nearest a specific address, with its real distance, use the ZIP lookup above.
Every figure above comes from these, and each is named so you can check it. Which station serves a given ZIP code, and how far away it is, varies across the metro — the table below gives it per ZIP code rather than this page averaging it.

Each of these takes a ZIP code and answers for that ZIP alone, citing the station it used and how far away it is. There is a ZIP box in the header of every page.

What survives my winter?
Runs on the hardiness zone, so it answers for all of Las Vegas-Henderson-North Las Vegas, NV at once — zone across 74 perennial fruits, berries, vegetables and herbs.
- When do I start my seeds?
Dates every spring job from your own last freeze — sow indoors, set out, direct sow.
- When do I sow the next round?
How often each crop is worth re-sowing, and when the next sowing is due.
- What can I still plant?
Counts the growing days left before your first fall freeze, crop by crop.

These metros span exactly the same zones — 8a–9b — so the same plants are in and out of range across them. The freeze dates and the spring calendar are their own.
Gardening in Nevada — zones 5a– 9b covers the whole state: how its 179 ZIP codes divide between 10 hardiness zones, and the freeze dates across every NOAA station in it.

Where these numbers come from
The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates are NOAA's 1991–2020 Climate Normals, read from every station whose normals cover a ZIP code in this metro. Nothing here is estimated, and no station stands in for another.
This page names no single station on purpose. Picking one to represent a metro sounds reasonable and is not: the station serving the most ZIP codes is an artifact of where ZIP centroids happen to fall, and it selects a lock on the Monongahela for Pittsburgh and a far southern suburb for Chicago. A range across every station is true; a single cited date for a whole metro is not.
