Hedge Plants for Nevada: What Holds, and What Only Looks Hardy

None of the 12 hedge species documented here survives the whole of Nevada. Zero. The state spans USDA zones 4a to 10a (USDA Plant Hardiness Zone Map 2023), and every one of the 12 holds in only part of that spread. So the useful question isn’t “what’s hardy in Nevada?” but “what’s hardy where my yard sits?” For the wider picture on hedge types, see Hedges.

What actually holds in Nevada

Start with the losses, since those are the expensive mistakes. Boxwood is documented only from zone 5a upward, so it fails at the coldest end. Leyland cypress and cherry laurel start at 6a, and they fail there too. At the warm end, privet, yew, arborvitae and eastern hemlock all stop at 7b. Cherry laurel and boxwood stop at 8b. Above 9b, one plant is left standing.

Here is what that looks like band by band, using only the species documented on this site.

Read that table as “survives,” not “thrives.” The upper end of a hardiness range is often a heat limit rather than a cold one, and the zone map itself is built on a single variable, the average annual extreme minimum temperature. It says nothing about how a plant handles a July afternoon in the low desert. A hedge listed at the edge of its range may live and still look tired.

Frost dates are a trap in the same way. NOAA NCEI’s 1991-2020 U.S. Climate Normals for the Las Vegas airport put the first 32°F freeze between December 8 and December 23, and the last one between January 7 and February 1. That is a desert urban-heat-island extreme, and it doesn’t describe Nevada. Reno, Carson City and anywhere at elevation freeze months earlier in fall and months later in spring. Get your dates from your county office through University of Nevada, Reno Extension.

A gardener in the hottest part of the state may find the Hedge Plants for Arizona: What Holds, and What Only Looks Hardy page closer to their conditions than a Reno neighbor’s yard is.

The hedges you can never cut back down

Nine of the 12 plants regrow from old wood, which means a hedge that gets too tall can be cut hard and will fill back in. Three don’t. Those three are the ones to think hardest about before buying, because a mistake can’t be undone with loppers.

Leyland cypress is the most tempting. It is documented from 6a through 10a, the widest reach of any plant here, and it grows 3 to 4 feet a year toward a screen of 15 to 25 feet. Prune it in late spring to midsummer. It does not regrow from old wood. Cut into the bare, brownish interior and that section stays bare. A Leyland that has outgrown its spot can only come out, not be cut down. That growth rate is roughly what boxwood manages in six to sixteen years, so the window for keeping it at size is short.

Eastern red cedar holds from 4a through 9b, growing 12 to 24 inches a year to 8 to 20 feet as a screen. Prune it in late winter, light cuts only. The “light cuts only” is the warning label: nothing you remove below the green comes back.

Arborvitae is slower, at 6 to 9 inches a year, and stays useful at 4 to 15 feet. It can be pruned in late winter before growth starts, or in midsummer. Its documented range ends at 7b, so it belongs in the cold and moderate parts of the state, not the warm valleys. It also doesn’t regrow from old wood.

The working rule for all three is to buy for the final height and plant at a spacing that gets you there, then trim lightly from the first year. Waiting until the hedge is too big is the one thing you can’t fix.

Compare that with the other nine. Yew, boxwood, privet, hemlock, hornbeam and both hollies all regrow from old wood, so a hard renovation cut is possible if it comes at the right time of year. That makes them forgiving choices for a clipped hedge that has to stay put next to a driveway or a property line.

Matching the plant to the job

Pick the job first, then check the zone band. A 3-foot border and a 20-foot windbreak call for different plants, and the table above narrows either list quickly.

For a low, clipped hedge, boxwood is documented at 2 to 6 feet and grows just 3 to 6 inches a year, pruned in late spring after the last frost. Slow is the point: less trimming, but a long wait to fill a gap. Yew (Taxus x media) is documented at 3 to 8 feet and 6 to 12 inches a year, pruned in late spring after the new growth hardens. Both sit in the cooler zones (boxwood 5a to 8b, yew 4a to 7b).

For a mid-height hedge of 5 to 15 feet, the hollies are the pair to know. Inkberry is evergreen. Winterberry loses its leaves in winter, so it won’t screen a window in January. Both are documented at 6 to 12 inches of growth a year and are pruned in late winter, while dormant, and both hold from 4a through 9b. Arrowwood viburnum grows faster, 12 to 24 inches a year to 6 to 10 feet, and is pruned right after flowering, in zones 4a through 8b.

Privet is the fast, tidy option in colder ground: 2 to 3 feet a year, 4 to 12 feet, pruned twice a season, in spring and midsummer. That means more work than any other plant here, and it stops at 7b.

For tall screens, the choices are Leyland cypress (15 to 25 feet), eastern red cedar (8 to 20 feet), eastern hemlock (10 to 20 feet, cold zones only, 4a to 7b) and cherry laurel (6 to 15 feet, 6a to 8b). American hornbeam runs 6 to 15 feet and holds from 4a through 9b, with midsummer pruning after the first flush. Hornbeam and both hollies are the only plants here that hold through 9b and regrow from old wood, which makes them the most forgiving picks if you’re in a warm zone.

A gardener who knows the humid East may recognize several of these; the Hedge Plants for Tennessee: What Holds, and What Only Looks Hardy page covers the same plants under very different rainfall.

The ground you are planting into

Zone answers the temperature question. It leaves the ground out completely. Nevada’s official state soil, adopted by law in 2001, is the Orovada series, an Aridisol, which is a dry-climate soil that is usually alkaline and often carries salts. USDA NRCS records its representative surface horizon at a pH of about 7.5, which is alkaline. It is sandy, with 66 percent sand, 8 percent clay and 26 percent silt, and it holds only about 1.4 percent organic matter. It is well drained.

Put that together and you get a tendency: water runs through fast, nutrients don’t stick, and the ground starts out on the alkaline side. A thirsty evergreen with shallow roots in a soil like that asks for steady irrigation for its first seasons. That is a general expectation, not a per-plant figure, since the hardiness ranges above cover cold and heat only. They don’t address alkalinity or salts. The hollies, for example, are eastern species, so it is worth asking the extension office how they do in local ground before you buy.

One caution matters more than any number here. The Orovada series represents the state, not your yard. These are the values USDA records for the surface layer of the major components of the mapped series (223 components, queried 2026-08-29), not a measurement of a worked garden bed. River bottoms, foothills and any lot a builder has scraped or filled will differ, sometimes completely. Never treat 7.5 as your pH.

This month, the useful work is small: look up your zone on the 2023 USDA map, cross-check it against the table above, and take a soil sample for a lab test. The test costs little next to a row of 20 shrubs, and your county’s extension office can point you to a lab.

Common questions

Is there any hedge plant that survives everywhere in Nevada?

Not among the 12 documented here. Across zones 4a to 10a, none holds statewide. Leyland cypress reaches the warmest zone (10a) but starts only at 6a. American hornbeam, both hollies and eastern red cedar span 4a through 9b, the widest cold-side range, and still miss 10a.

Can I cut back an overgrown Leyland cypress, red cedar or arborvitae?

No. All three fail to regrow from old wood, so cutting into bare interior leaves permanent gaps. The other nine species can take renovation pruning at the right time of year, which is why the choice matters before planting.

Can I use Las Vegas frost dates to plan my planting?

Only if you garden right there. NOAA NCEI’s normals for the Las Vegas airport (first 32°F freeze December 8 to December 23, last January 7 to February 1) reflect a desert urban heat island. Reno, Carson City and higher ground freeze much earlier in fall and later in spring. Ask your county extension office for local dates.

How do I find my zone?

Use the USDA Plant Hardiness Zone Map (2023 edition, built on 1991-2020 normals). It rests on one variable, the average annual extreme minimum temperature, so it says nothing about summer heat or soil. Pair it with a soil test and a call to your local extension office.
