The difference between a yard you enjoy and a yard you hide from often comes down to one thing: height. Giant evergreen trees deliver that vertical presence, transforming open space into private, structured landscapes with dense foliage that blocks wind, noise, and prying eyes. Whether you need a fast-growing privacy screen or a long-term anchor for your property line, the right species and planting strategy make all the difference.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years analyzing plant growth data, comparing nursery stock quality, and studying hardiness zone maps to understand which giant evergreens actually deliver on their promises for real homeowners.
After reviewing dozens of specimens and thousands of owner reports, I’ve narrowed the field to the seven best options that balance growth rate, mature size, and adaptability. This guide to the best giant evergreen trees covers what matters most when investing in trees that will shape your property for decades.
How To Choose The Best Giant Evergreen Trees
Buying giant evergreens is a long-term investment in your property’s structure. The wrong choice means years of frustration — bare patches, uneven growth, or trees that outgrow the space you gave them. Here’s what separates a smart purchase from a regret.
Growth Rate and Mature Size
Fast-growing species like Thuja Green Giant can add 3 feet per year, but they also reach 40-60 feet tall at maturity. You must plan for that final height, not just the first few seasons. If your space is tight around foundations or power lines, a slower-growing species like Emerald Green Arborvitae (topping out around 12-15 feet) is the safer play. Always check the expected mature width too — Thuja Green Giant spreads 15-20 feet wide, meaning 6-7 foot spacing is the minimum for a solid screen.
Hardiness Zone Match
Most giant evergreens thrive in zones 5 through 9, but winter survival in zone 4 or summer heat in zone 10 requires specific cultivars. Thuja Green Giant handles cold well but struggles in extreme drought without irrigation. Emerald Green Arborvitae adapts to a wider range of soil types but needs moderate watering. Never order trees that ship to zones outside their proven range — many sellers restrict shipping to certain states for this reason.
Nursery Stock Quality Indicators
The biggest mistake beginner buyers make is judging a tree by its top growth alone. Look for descriptions that mention root system health — potted liners with established roots transplant far better than bare-root alternatives. Trees shipped in their original soil and container (as most quality sellers do) suffer less transplant shock. Also check for mentions of deer resistance and drought tolerance; these features save you constant maintenance down the road.

In‑Depth Reviews
1. Thuja Green Giant 40 Live Plants
This is the ultimate bulk solution for anyone who needs a dense, fast-growing privacy screen across a large property line. With 40 individual plants, you can cover a 240-280 foot stretch at the recommended 6-7 foot spacing, creating a living wall that adds 3 feet of height per season once established. The Thuja Green Giant hybrid delivers exactly what the name promises — giant growth potential in a manageable package.
The plants ship as potted liners in their own soil, which dramatically reduces transplant shock compared to bare-root alternatives. Florida Foliage, the grower behind this offering, has a strong reputation for shipping healthy stock with intact root systems. The key spec here is the number of pieces — 40 plants at this price point represent significant value per unit for large-scale landscaping projects.
One important note: these trees require consistent irrigation during the first month after installation. Sandy soil types work well, but you must stay on top of watering until the roots establish. For commercial properties, large residential lots, or anyone building a serious windbreak, this is the volume play that works.
What works
- Bulk 40-pack covers large areas efficiently
- Potted liners reduce transplant shock significantly
- Fast 3 ft/year growth once established
What doesn’t
- High initial watering requirement for first month
- Not suitable for zones outside 5-9
2. Thuja Green Giant 2 Extra Large 3 Gallon Trees
If you want a head start on privacy without waiting for tiny liners to size up, this 2-pack of extra-large 3-gallon trees is your answer. The larger container means the root system is more developed at shipping, giving you a stronger tree that establishes faster and withstands the first growing season better than smaller stock. For homeowners planting just a few accent specimens or starting a small hedge, starting with this size reduces the time to maturity by a full year or more.
Florida Foliage ships these with the same care as their bulk offerings — potted in soil, ready to go into the ground. The 3-gallon size handles transplant stress noticeably better, with owners reporting near-zero losses when planted correctly. The style name specifies 2 plants, so plan your spacing accordingly if you need more than two.
The premium nature here isn’t about luxury; it’s about buying time. A 3-gallon tree has roughly double the root mass of a 1-gallon liner, meaning faster vertical growth in year one and denser foliage from the start. For anyone who values immediate landscape impact, this is the smart upgrade.
What works
- 3-gallon containers mean bigger root systems
- Faster establishment and first-year growth
- Minimal transplant shock reported
What doesn’t
- Only 2 trees per order limits coverage area
- Higher upfront cost per tree than liners
3. Brighter Blooms Emerald Green Arborvitae 5-6 ft
For tight spaces where a full-sized giant would overwhelm, the Emerald Green Arborvitae is the refined alternative. Topping out at 12-15 feet with a narrow 3-4 foot spread, this tree fits alongside foundations, driveways, and fence lines without the aggressive spread of a Thuja Green Giant. The 5-6 foot starting height means you get immediate visual impact — no waiting 3 years for a privacy screen to reach eye level.
Brighter Blooms backs this with a warranty program, though the 30-day window is tight for root establishment. Shipment restrictions apply to AK, AZ, HI, and OR due to federal regulations, so verify your state before ordering. The natural pyramidal shape requires no pruning to maintain its tidy appearance, making it a low-maintenance choice for gardeners of all experience levels.
Owner feedback highlights the excellent customer service for replacements, but some report variability in foliage density at this price point. The tree adapts well to varying soil types and weather extremes, making it a reliable performer in zones 3-8. If your priority is a medium-height, sculptural evergreen that doesn’t eat your entire yard, this is the pick.
What works
- Pre-grown 5-6 ft size offers instant privacy
- Compact 3-4 ft width fits tight spaces
- No pruning needed to maintain shape
What doesn’t
- Shipping restricted to several states
- 30-day warranty may be short for root establishment
4. 25 Thuja Green Giant Arborvitae 8-14″ Tall
At this price for 25 trees, you’re getting the lowest per-plant cost in the lineup — ideal for budget-conscious buyers willing to wait an extra season for the trees to size up. The 8-14 inch starter height is small enough to ship easily, and the Thuja genetics ensure rapid growth once planted. Spaced 6-7 feet apart, these 25 trees can cover a 150-175 foot privacy screen.
The trees ship as potted plants in their soil, which is critical for survival rates. Owner reports consistently praise the root structure at this size — the plants arrive green and alive with decent root development despite the small top growth. Zone 5-9 adaptability covers most of the continental US, and the full sun requirement is standard for this species.
Winter survival can be a concern in colder zone 5 areas, with some owners reporting losses after the first winter if the trees weren’t fully established before the freeze. The moderate watering needs are manageable, but sandy soil is recommended for best drainage. If you have the patience to nurture small starts and the land to space them properly, the value here is unbeatable.
What works
- Lowest per-plant cost in the comparison
- Potted with soil for reduced transplant shock
- Strong root structure reported by buyers
What doesn’t
- Small 8-14 inch starts need patience
- Higher winter loss risk in colder zone 5 areas
5. Perfect Plants Thuja Green Giant 2 ft 8-Pack
This 8-pack hits the sweet spot for homeowners needing a moderate-sized hedge without committing to 25 or 40 trees. The 2-foot starting height gives you a meaningful head start over smaller liners, and 8 plants spaced 6-7 feet apart cover roughly 48-56 linear feet — perfect for a backyard border or side-yard privacy screen. Perfect Plants has earned strong reviews for packaging quality and tree health on delivery.
The dense, dark green foliage carries that classic Christmas-tree scent when crushed, and the wide-bottomed pyramidal shape fills in quickly at the base — no bare legs at the bottom. The trees are adaptable to zones 5-9 and require full sun for optimal growth. Owner reviews consistently mention healthy root systems and plants arriving in excellent condition, with multiple 5-star ratings praising the quality.
Some buyers note that not all trees hit the advertised 2-foot mark, with a few arriving closer to 18 inches. This is within normal variability for shipped nursery stock, but worth noting if you need uniform height immediately. Once established, these trees need little maintenance beyond occasional watering during dry spells.
What works
- 2-foot starting height reduces wait time
- Excellent packaging and tree health ratings
- Compact 8-pack fits medium-sized properties
What doesn’t
- Some trees arrive slightly shorter than 2 ft
- Not the most cost-effective for very large areas
6. Perfect Plants Thuja Green Giant 18-Pack
This 18-pack from Perfect Plants offers a middle ground between the small 8-pack and the massive 40-plant bulk orders. With 18 individual liners, you can cover 108-126 linear feet at proper spacing, making it ideal for a full backyard perimeter or a substantial side-yard screen. The key differentiator here is the included deer resistance and drought tolerance features — two practical benefits that reduce your ongoing maintenance burden significantly.
The trees ship as liners, meaning they are smaller starter plants that will need a season or two to reach privacy height. However, the Thuja Green Giant genetics mean they’ll add 3-4 feet per year once established, so the wait is shorter than with slower-growing evergreens. The 7-pound shipping weight confirms these are lightweight liners rather than heavy potted specimens.
A critical restriction: this 18-pack cannot ship to California or Arizona due to agricultural regulations. If you’re in those states, you’ll need to seek alternative sourcing. The drought tolerance is a genuine advantage for owners in drier regions, reducing the irrigation burden after the first year. For large, deer-prone properties, this is a practical and cost-effective solution.
What works
- Deer resistant and drought tolerant once established
- 18 plants cover 100+ linear feet
- Fast growth genetics minimize wait time
What doesn’t
- Cannot ship to CA or AZ
- Small liner size requires patience for height
7. Mavis’s Diary Artificial Cedar Topiary 2-Pack
This entry is a different category entirely — artificial evergreens for buyers who want the look without the maintenance. The 5-foot height and compact pyramidal shape mimic a real cedar topiary, but with zero watering, pruning, or seasonal care. Made from UV-resistant PE material, these hold their color through sun and rain without fading or cracking, making them suitable for covered porches, patios, and entryways.
The set comes ready to display with square black pots and fillable water bags for wind stability — no separate planters needed. Assembly takes minutes: remove from box and fluff branches to desired fullness. The realistic detail is convincing enough that multiple owners report visitors asking if they’re real. The drainage hole in the pot adds practicality for outdoor use.
The trade-off is obvious: they don’t grow, they don’t provide the environmental benefits of real trees, and the 5-foot height is fixed. The plastic base pots are lightweight and may need extra weighting (rocks or the included water bags) to stay upright in strong wind. For renters, apartment dwellers with balconies, or anyone who wants instant greenery without commitment, this is a viable alternative.
What works
- True zero-maintenance — no watering or pruning
- UV-resistant material holds color outdoors
- Includes pot and water bags for wind stability
What doesn’t
- Fixed 5-foot height will not grow
- Base pots may need extra weighting in wind
Hardware & Specs Guide
Spacing for Privacy Screens
Thuja Green Giant trees need 6-7 feet of spacing between specimens to develop properly while creating a dense screen. Closer spacing (4-5 feet) forces competition and thins out the lower foliage. Wider spacing (8-10 feet) leaves gaps that take years to fill. Measure your total linear footage and divide by 6.5 to get the minimum number of trees needed. For a 100-foot property line, that means 15-16 trees in the ground.
Soil and Watering Requirements
All Thuja varieties prefer well-draining sandy soil with moderate moisture. Consistent irrigation during the first month after transplanting is critical — the root system must establish before the tree can tolerate dry spells. After year one, established Thuja Green Giants show good drought tolerance but still benefit from deep watering during extended dry periods. Avoid clay-heavy soils that retain water and cause root rot.
