9 Fastest-Growing Privacy Bushes That Add Up to 5 Feet a Year (Not Marketing Hype)

Nursery tags love to promise “fast growth” without saying how fast, and garden blogs round every number up to make the list look better. I went straight to university extension data instead — the same sources horticulturists cite — and cross-checked every growth-rate claim below against it. Nine bushes made the cut. Three popular ones didn’t, and I’m telling you why.

Wax Myrtle tops the list at up to 5 feet of growth in a single season, according to Clemson Cooperative Extension[1]. That’s the ceiling, not the average — most of the bushes here settle into 1 to 3 feet a year once established.

Why Growth-Rate Numbers Almost Never Match What You See in Your Yard

A shrub planted from a 3-gallon container spends its first year putting energy into roots, not height — the visible growth spurt usually doesn’t start until year two or three. That’s the mechanism behind the most common complaint in nursery reviews: “it grew 6 inches, not 5 feet.” The 5-feet-a-year figure for Wax Myrtle is a single-season number for an already-established plant, not a promise for the year you plant it. Budget an establishment year before you count on the marketed growth rate.

Evergreen Picks: Privacy You Don’t Lose in Winter

Wax Myrtle (Myrica cerifera)

This is the fastest bush on the list, and the only one rated for salt spray and standing wet soil — Clemson Extension notes it tolerates “drought, sand, sun and salt spray” and grows well in average to poor drainage[1]. It’s hardy in zones 7–10; the ‘Hiwassee’ cultivar pushes cold tolerance a bit further north. At 15–20 feet mature height and width, give it real room — it’s not a plant-and-shear hedge, it’s a screen.

Nellie Stevens Holly (Ilex ‘Nellie R. Stevens’)

NC State Extension rates this cross between English and Chinese holly as a rapid grower with excellent dark green foliage and berries[3]. Unlike two of the bushes we cover in the skip-list below, it carries no invasive-species flag and none of Red Tip Photinia’s chronic leaf-spot problem — it just holds its color through winter without complaint. Give it full sun to part shade and watch for leaf spot or powdery mildew in humid climates, though neither is common.

Skip Laurel (Prunus laurocerasus ‘Schipkaensis’)

Skip Laurel earns a spot for shade tolerance most evergreens on this list don’t have. One caveat competitors skip entirely: all parts of this plant — stems, leaves, seeds — contain cyanogenic glycosides, and the toxicity is highest when the foliage is wilting, wind-damaged, or frost-bitten[7]. NC State Extension confirms the same risk for this cultivar specifically[6]. That’s not a reason to avoid it — it’s one of the most-planted privacy shrubs in the South — but keep dogs and grazing livestock away from fallen or pruned clippings, and skip it near goat or horse pasture fencing.

Chindo Viburnum (Viburnum awabuki ‘Chindo’)

The most underrated bush on this list. NC State Extension lists it as a rapid grower that tolerates both full sun and shade — unusual for an evergreen this dense — with good drought resistance once established[10]. It’s semi-evergreen rather than fully evergreen in colder pockets of its range, so factor that in if you’re near the edge of its hardiness zone.

Japanese Privet (Ligustrum japonicum)

Privet gets a bad reputation it doesn’t uniformly deserve. Japanese Privet grows a documented 25 inches or more per year and takes shearing better than almost anything on this list, according to Clemson Extension[2] — but the same factsheet flags Chinese Privet as a “severe threat” invasive species in South Carolina, and Common and European Privet have both escaped cultivation into the wild via bird-dispersed seed. Read the tag. “Privet” on its own isn’t a species — which one you buy determines whether you’re planting a hedge or a habitat problem.

Deciduous Picks Worth the Trade-Off

Every bush in this section loses its leaves in winter — you’re trading four months of bare branches for faster growth, disease resistance, or flowers evergreens can’t match.

Ninebark (Physocarpus opulifolius)

NC State Extension rates Ninebark’s growth rate as rapid — 2 feet or more in a year — and calls it “relatively trouble free,” tolerant of heat, drought, and compacted soil[9]. It’s native to most of the eastern US, so it won’t become the next Burning Bush. The trade-off: it’s deciduous and won’t give you a solid winter screen on its own.

Forsythia (Forsythia spp.)

Forsythia only flowers on wood that grew the previous year — prune it between mid-summer and late winter and you cut off next spring’s blooms before they form, per Iowa State University Extension[8]. Prune immediately after flowering instead, and remove a quarter to a third of the oldest stems at ground level every other year to keep a mature hedge dense rather than leggy. Most cultivars reach 8–10 feet; in cold climates, stick to hardy selections like ‘Meadowlark’ or ‘Northern Sun.’

Rose of Sharon (Hibiscus syriacus)

Rated a rapid grower by NC State Extension, reaching 8–12 feet tall[11]. It’s the only bush on this list that doubles as a pollinator magnet — hummingbirds and bees work the summer-long flowers hard. As a privacy screen it’s mediocre in winter and can self-seed aggressively in mild climates; deadhead spent blooms if volunteer seedlings bother you.

Arrowwood Viburnum (Viburnum dentatum)

Honest disclosure: this is the slowest bush on the list, rated “medium” growth by NC State Extension, not rapid[5]. It earns its spot anyway — it’s native to most of the eastern US, supports Spring Azure butterfly larvae and songbirds, and never needs an invasive-species disclaimer. If you’d rather wait an extra year than plant something your state extension office will eventually ask you to remove, this is the pick.

3 Popular “Fast Privacy Bushes” We Left Off This List

Red Tip Photinia. It’s fast, it’s everywhere, and University of Maryland Extension calls Entomosporium leaf spot “one of the most common and significant diseases” it faces — with no resistant cultivars available and infected plants typically defoliating before mid-summer[4]. UMD’s own recommendation isn’t to spray — it’s to replace the plant with something else. We’re skipping the step where you plant it first.

Chinese Privet and Burning Bush. Both grow fast, and both show up on state invasive-species lists for it — NC State Extension flags Euonymus alatus (Burning Bush) as invasive from Connecticut to South Carolina and west to Wisconsin, and states outright that “this plant is problematic and alternatives should be considered.”[12] Its own suggested native alternative? Viburnum dentatum — Arrowwood, the same bush that made our list at #9. Chinese Privet gets the same treatment from Clemson Extension, which rates it a “severe threat” in South Carolina[2].

Leyland Cypress. Not disqualified, just not a bush — left mature, it’s a 40-foot-plus tree that happens to grow 3–5 feet a year. It’s also vulnerable to Seiridium canker, a fungal disease with no known cultivar resistance that can kill entire trees[13]. If you want that growth rate and have room for a tree-sized screen, we cover the canker risk and full care profile in a dedicated Leyland Cypress guide rather than repeating it here.

How Soon You Actually Get a Screen

Most of these bushes ship from the nursery at 2 to 3 feet tall in a 3-gallon container. Add the growth rates above and a realistic timeline looks like this: a 2-foot Wax Myrtle planted this spring, growing at its established rate of up to 5 feet a year starting in year two, reaches a 6-foot screening height by the end of year two — not year one, because of the root-establishment lag. A 2-foot Japanese Privet at roughly 2 feet a year takes closer to three years to hit the same height, but tolerates tight shearing into a formal wall the whole time. As a general spacing guideline, closer planting fills gaps faster but crowds roots sooner — for Nellie Stevens Holly specifically, most growers recommend 5 to 6 feet between plants for a dense privacy hedge, tighter than its 8–25 foot mature spread would suggest, because regular shearing keeps it in bounds. Tighter spacing means more plants and more up-front cost in exchange for a faster-closing screen.

Picking the Right Bush for Your Zone

This list splits cleanly along one line: the evergreens need a warm zone, the deciduous picks don’t. Wax Myrtle (zones 7–10), Japanese Privet (7b–10a), Chindo Viburnum (7–9), and Skip Laurel and Nellie Stevens Holly (both commonly rated 6–9) won’t reliably survive a zone 3–5 winter. Ninebark (zones 3–7) and Arrowwood Viburnum (zones 3–8) will — both are rated for the same cold-hardy range as spruce and arborvitae. Forsythia and Rose of Sharon sit in between, hardy to roughly zone 4–5 depending on cultivar. So if you’re in zone 3–5 and want year-round evergreen privacy rather than a deciduous trade-off, our guide to cold-hardy privacy trees for zones 3–6 covers spruce, arborvitae, and pine options built for that range. If speed matters less to you than a specific formal or flowering look, our hedge plants guide ranks 15 options beyond just growth rate.

FAQs

What’s the single fastest-growing privacy bush?

Wax Myrtle, at up to 5 feet of growth in a single established season, per Clemson Extension[1]. It’s rated for zones 7–10 and needs room to reach its 15–20 foot mature spread.

Is Burning Bush actually illegal to plant?

It depends on your state — several Northeastern and Midwestern states restrict or ban its sale, and NC State Extension lists it as invasive from Connecticut to South Carolina and west to Wisconsin[12]. Check your state extension office or agriculture department’s regulated-plant list before buying — rules change by state and sometimes by county.

Are any of these bushes toxic to pets?

Skip Laurel is the one to watch — its stems, leaves, and seeds contain cyanogenic glycosides that are most concentrated when the foliage is wilting or frost-damaged, according to the ASPCA[7]. Keep dogs, cats, and grazing animals away from fallen clippings, especially after pruning or a hard frost.

Can I mix evergreen and deciduous bushes in the same privacy screen?

Yes, and it often looks better than a monoculture hedge — evergreens like Nellie Stevens Holly or Chindo Viburnum anchor winter privacy while deciduous bushes like Forsythia or Rose of Sharon add seasonal color and faster early fill-in. Just plant evergreens on the section that needs year-round screening (facing a neighbor’s window, for example) and save the deciduous mix for spots where a few bare months in winter don’t matter.
