You need height for privacy, a screen against a neighbor, or a vertical accent by an entryway, but you have only a few feet of horizontal space. Skinny trees solve that. These are trees bred for a columnar or narrow growth habit, so you get the screening power of a big evergreen without it swallowing your whole yard. Here is how the best narrow evergreens actually perform — how fast they grow, how tall they get, and how much care they truly need.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
If you need to block a view or frame a doorway without sacrificing yard space, choosing the right skinny trees for landscaping means matching mature height and spread to your actual planting strip.
Our Picks at a Glance
How To Choose The Best Skinny Trees For Landscaping
Every tree on this list shares one trait — a narrow, upright shape — but they differ wildly in mature size, growth speed, and winter hardiness. Matching the tree to your exact spot is the whole game. Here are the three decisions that matter most.
Match the Mature Height and Spread to Your Space
The little potted plant you receive is a promise, not the final product. A tree like the Emerald Green Arborvitae matures at 18–20 feet tall, so it suits a tall privacy screen, while the Dwarf Alberta Spruce stays a more compact 6–8 feet. Always check the mature spread too — a tree that reaches 3–4 feet wide demands that much clearance from walls and walkways.
Understand Your Hardiness Zone First
Your USDA hardiness zone tells you which trees can survive your local winter. The Weeping White Spruce survives zone 2 winters, making it a top pick for brutally cold climates., while the Emerald Green Arborvitae is rated for zones 3–8. If a tree’s zone range does not include your area, do not count on it lasting more than a season.
Decide How Fast You Need the Screen
Some narrow trees are slow, steady growers — the Emerald Green Arborvitae and the Dwarf Alberta Spruce build their height patiently. Others, like the American Pillar Arborvitae, are bred to put on at least 3 feet per year once established. If you want privacy within a couple of seasons rather than a decade, growth rate becomes your top filter.

In‑Depth Reviews
1. Live Plant Green Promise Farms Thuja Arborvitae ‘Smaragd’
Our pick — over 4.5★ from 150+ verified ratings; the strongest balance of quality and price.
The classic narrow evergreen that delivers real privacy height, in a 12-pound pot ready for your yard.
If you want the proven workhorse of skinny screening, this is it. The Thuja occidentalis ‘Smaragd’ grows into a tall, upright, narrow evergreen with rich emerald green foliage, reaching a mature height of 18–20 feet with a spread of just 5–6 feet. That means a solid privacy wall that never invades your lawn. It arrives fully rooted in a #3 size, 3-gallon container, ready to plant immediately, weather permitting.
Owners consistently land on the same verdict: these are high-quality trees with lush green color and a healthy two-foot stature on arrival. The thing everyone raves about is the quality — buyers single it out more than any other trait — followed closely by the appearance. One happy customer called them “absolutely beautiful” and praised the fast shipping, while another noted their tree was still doing well a full 12 months later.
It grows well in both partial shade and full sunlight, and it is rated for USDA Zones 3–8, so it handles a broad range of climates. The one honest caveat from the review pages is that plants can arrive a little dry after shipping, though most bounce back to full green with water and time.
Dense emerald screen
- Strong, healthy trees with rich emerald foliage
- Tall 18–20 ft mature height for real privacy
- Arrives fully rooted in a 3-gallon container
Needs steady moisture
- Can arrive slightly dry from shipping
- Needs 5–6 ft of width at maturity
Top pick: home gardeners who want the time-tested narrow evergreen for a tall privacy hedge in zones 3–8.
Skip if dry: you need instant full screening this season — this one grows tall with patience, not overnight.
2. Sky Pencil Japanese Holly (10 Live Plants)
A pencil-thin column that grows skyward naturally, no trimming needed, for — ideal flanking a door.
This is the tree for a sleek, formal statement. The Sky Pencil Holly has a narrow, columnar form with dark green foliage that stays neat year-round, and it often sports small purple berries in fall when a male pollenizer is nearby. Its leaves lack sharp points, so it is safe to brush past on decks, patios, or entryways. The shape grows skyward on its own — you only prune if you want to hold it at a specific height.
What wins people over is the health of the plants on arrival — that is the trait owners praise most — followed by their growth. One buyer called the service “amazing” after getting a species recommendation that arrived happy and healthy, while another noted it was the most affordable way to obtain 30 of these plants. At just 5 pounds for the set of 10, it is a light, easy shipment.
The honest trade-off is size: these arrive as young, small plants. As one buyer put it, “the plant’s height is about the same height of the pot,” so manage expectations against the product photos. Compared to the 12-pound single Emerald Green Arborvitae, you are getting far more plants here but each one is a youngster that needs growing time.
Narrow upright form: pairs at a front entry, flanking a fountain, or lining a narrow side yard for a windbreak. Think of them as living columns you grow yourself, not instant screens.
3. Weeping White Spruce (Picea glauca ‘Pendula’)
A formal, narrow spruce with drooping branches, hardy to –50°F for the coldest gardens in America.
For gardeners in truly frigid climates, this is the narrow tree that can take it. The Weeping White Spruce has a formal, narrow, conical shape with pendulous, stiffly held, drooping branches and loads of light gray-green foliage. It survives –50°F winters and reaches 10 feet tall, forming a striking vertical accent that withstands extreme cold. It is rated for Zones 2–8.
Experiences here genuinely split. Some buyers received healthy, vibrant plants and were “very satisfied” with the open pot bottom that lets you remove the root ball without disturbance. Others watched their trees die — as buyers report, one “looked fine all summer but did not make it through the winter,” and the tree was small enough that they would have chosen something else had they known. Survival seems to hinge on giving these tiny, tender newcomers careful watering through their first hot summer.
At maturity it holds a tight shape, but the journey there is slower and riskier than the Emerald Green Arborvitae above. This is a fit for patient gardeners in cold zones who expect to baby a young tree through its first year.
Statement tree: you live in zones 2–8, want a weeping narrow silhouette, and will commit to watering a fragile young tree.
Skip small yards: you want a sturdy, guaranteed survivor — reviews here are the most divided on the list.
4. Green Giant Arborvitae (10 Pack, Thuja Plicata)
A vigorous, fast-growing evergreen that shoots up as much as 3 feet per year for a quick windbreak.
When speed is the priority, this is the pick. The Green Giant Arborvitae is a large, vigorous, fast-growing evergreen that can shoot up by as much as 3 feet per year until maturity, with a natural pyramidal to conical form and dense, rich green foliage that bronzes slightly in winter. It resists deer and bagworms, withstands heavy ice and snow, and grows in almost any soil, including sandy loam or heavy clay.
The seed quality is what owners praise most, followed by the appearance. Some owners mention their trees are “healthy and strong” and rebuy year after year, while others love that the arborvitae arrived “packed in an incredibly safe fashion” with great root systems. It thrives in southern heat and humidity, which narrows its appeal to warmer zones.
The catch is the same one that runs through several picks here: the size is mixed. As one buyer put it plainly, “you will get tiny 6-7 inches plants and not 3 feet as advertised.” Buyers also note the health of plants varies, with some dying within two weeks. This is a fast-growing species, but your first season is about coaxing small rooted plants to establish rather than enjoying instant height.
Quick cover: warm-climate gardeners who want the fastest possible evergreen screen and are ready to nurse young plants through year one.
Not for tight spots: you expect the advertised size on day one — set your expectations to sapling, not tree.
5. Dwarf Alberta Spruce (Picea glauca ‘Conica’)
A slow-growing, densely packed cone that tops out at 6–8 feet — perfect for porch planters and small beds.
This is the narrow evergreen for tight, tidy spaces. The Dwarf Alberta Spruce has a dense, conical shape with a slow growth habit and rugged dependability, maturing at just 6–8 feet tall with a 3–4 foot spread. That modest footprint makes it a natural fit for wooden porch planters or a small garden bed where a full-size tree would overwhelm. It grows well in full sun or partial shade and is rated for zones 3–8.
The appearance is what wins everyone over — it is the most-praised trait by a wide margin — with quality close behind. Multiple buyers describe the trees as “beautiful, full and healthy,” arriving extremely well packaged and ready to thrive after transplanting. One owner specifically praised it as better quality than what they found at local stores, and several noted the size was exactly as listed.
Compared to the much larger Emerald Green Arborvitae, this compact spruce trades screen height for a manageable, low-maintenance silhouette. It does not need pruning to hold its shape, which makes it the easiest pick here for a beginner who just wants a handsome evergreen that stays put. Growth stories do vary — some trees thrive with new growth, others died suddenly — but the overwhelming majority are delighted.
Compact pyramidal shape: for a small, self-shaping evergreen in a planter or tight corner, this is the most reliable, most-loved option on the list.
6. Spartan Juniper (20 Live Trees, Juniperus Chinensis)
A stately dark green column that tolerates heat, cold, and drought — the classic source of spiraled topiary.
If you want a Mediterranean feel or a sculpted topiary, the Spartan Juniper is your tree. It forms a stately, dark green, densely branched column reaching 15 feet tall, and it is the source of the lovely spiraled topiary columns so popular in Mediterranean-inspired gardens. Its symmetrical, pyramidal shape rarely needs pruning in natural form, and it tolerates heat, cold, and drought once established — a genuinely adaptable evergreen.
Health is what owners praise most, with the size being the recurring point of debate. Some buyers planted all of them on drip water as a privacy wall and are waiting to see them root, while another loved that the pack was “tiny and well packaged” and arrived without being jumbled in the box. For the quantity — 20 live trees — the value is real if you are building a long screen line.
That said, “tiny” is the word that comes up again and again. As one owner noted, the plants were only about 3 inches tall on arrival, and the photos look bigger than reality. Some buyers lost half their plants before they could get them in the ground. This is a starter pack for someone who enjoys growing on young trees, not for impatient landscapers. It grows best in full sun with well-drained soil — avoid overly wet conditions.
Tough choice: Mediterranean-style gardens and anyone building a long, uniform screen line on a budget with time to grow.
Avoid kids: you want immediate height — these arrive as roughly 3-inch saplings that need a full season to establish.
7. Arborvitae Emerald Green (3 Live Gallon Size Trees)
A narrow pyramidal evergreen that holds emerald color through winter — plant every 3 feet for a no-trim hedge.
Here is a hedge that practically builds itself. This Emerald Green Arborvitae has a narrow, pyramidal form with dense foliage that holds its color throughout winter — you will not deal with ugly browning even in the coldest winters. It reaches just 12–14 feet tall with a 3–4 foot spread, and the grower promises you can plant every 3 feet for a tidy, neat hedge that never needs trimming. It also does fine in large decorative pots by a doorstep.
Health is the trait buyers praise most — the trees arrive “beautiful and healthy” and “fresh, and nicely packed.” Florida Foliage earns consistent credit for careful packing. The big frustration is the size, which is the single most-discussed issue and reads as negative. Multiple buyers found the trees far smaller than expected; the plants arrived in 2.5 quart buckets rather than true 1-gallon pots, with one order measuring just 12 to 16 inches tall.
This is a slower grower than the Green Giant — the listing itself admits the ‘Green Giant’ cultivar is faster — but the trade-off is that the size of this slow grower is often just about right for a privacy hedge. Go in knowing you are buying healthy young plants, not the mature height you see in the photos.
Classic green hedge: a beautiful, healthy, well-packed tree if your expectations are set to young sapling size. Buy for the long-term hedge, not for instant coverage.
8. Thuja Arborvitae Green Giant (10 Live Quart Size Plants)
A rapidly growing pyramidal evergreen that can reach 30–50 feet — the ultimate tall privacy barrier.
For the tallest possible screen, this is the tree that delivers. The Thuja Green Giant is a rapidly growing, broad pyramidal evergreen with medium to dark green foliage that grows 30–50 feet tall. It is ideally used for a decorative accent or a wind and privacy screen, and the grower recommends planting one every 5–6 feet to quickly create a dense barrier. Once established, it tolerates drought and adapts to a wide range of soils, including saturated ones. It is rated for cold hardiness Zones 5–9.
The growth is what owners praise most — it is the top positive aspect by a clear margin — with tree quality close behind. Buyers consistently report the trees arrived “very healthy and are thriving,” and one impressed owner said they were ordering 250–300 more after seeing the condition of the arrival. Another noted these outperformed expensive blue spruces from a big-box store, growing faster and healthier.
The one requirement to know: the first year needs regular water, at least once per day, to establish that root system before it becomes drought tolerant. Patience with daily watering through year one is the price of admission for the 30–50 foot pay-off later. Compared to the Emerald Green picks above, this is the species for someone who truly wants maximum height, not a modest hedge.
Fast filler: a fast, tall, healthy screen in warm zones (5–9) if you will commit to daily first-year watering.
Not small lots: you have no patience for a daily watering schedule — the root system demands it in year one.
9. American Pillar Arborvitae (10x Quart Pots)
A truly fast-growing narrow screen that adds at least 3 feet per year after its first season in the ground.
Here is the narrow tree for fast privacy. The American Pillar Arborvitae is billed as a truly fast-growing arborvitae — plant a 1 to 2 foot tall plant, and after the first year it begins growing at least 3 feet each year. Its narrow growth habit makes it perfect for blocking views to pools, neighbors, patios, and decks, and the grower suggests spacing plants 2.5 to 3 feet apart for a hedge in just 2 to 3 years. It matures at a substantial 20–30 feet tall.
The growing is what owners praise most — it is the top positive aspect — with healthiness right behind it. Multiple buyers raved about the quality, with one calling it “one of the healthiest and nicest plants I’ve ever bought online,” and another noting their 50+ American Pillar Arborvitae grew several inches and are thriving after three months. The nursery backs every order with a 14-day guarantee from delivery, reducing the risk of an online tree purchase.
It is rated for Zones 3–8, grows in full sun or partial shade, and resists deer and disease. The trade-off relative to the taller Thuja Green Giant is height — this one stops at 30 feet where the Green Giant can hit 50 — but its narrow habit means it fits tighter spaces while still gaining ground fast. It is also the priciest option here, so weigh that against the speed and the 10-plant quantity.
Formal look: the fastest narrow hedge possible in zones 3–8, backed by a 14-day nursery guarantee.
Skip if wild: your budget is tight — this is the premium-priced speed option on the list.
Understanding the Specs
Mature Height vs. Spread
The single most important pair of numbers on any tree listing. Height tells you the screening power; spread tells you how much horizontal room it will eventually claim. A tree that matures at 18–20 feet tall with a 5–6 foot spread needs that width of clearance, while a compact spruce at 6–8 feet with a 3–4 foot spread fits a planter. Always plan for the mature tree, not the sapling you unbox.
USDA Hardiness Zones
Your hardiness zone is a map of the coldest average winter temperatures in your area. Trees are rated for the zones they can survive in — the Weeping White Spruce handles zone 2, while the Thuja Green Giant needs zones 5–9. If your zone falls outside a tree’s range, it may not survive its first winter. Check your zone before you buy, not after.
Growth Rate Per Year
Growth rate decides how long you wait for privacy. Fast growers like the American Pillar Arborvitae and Green Giant can add 3 feet per year once established, building a screen in a couple of seasons. Slow growers like the Dwarf Alberta Spruce build height patiently over many years. There is no wrong answer — just match the speed to how quickly you need the coverage.
Container Size and Root Condition
The container size at delivery tells you how established the root system is. A #3 size 3-gallon container holds a more mature root ball than a quart pot, which means faster establishment and less babying after planting. Quart-size plants are younger, smaller, and need more care through their first season. Buy the biggest container your budget allows for the easiest start.
