A living privacy screen that reaches 30 to 60 feet tall doesn’t happen by luck — it starts with choosing the right cultivar, root system, and planting strategy from day one. Giant arborvitae trees are the backbone of many landscape designs, offering dense evergreen foliage, rapid vertical growth, and year-round screening that no fence can match. But the difference between a thriving hedge and a sparse row of struggling plants comes down to selecting the correct species for your zone, soil type, and sun exposure.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years studying nursery stock quality, comparing root development across pot sizes, and analyzing aggregated owner feedback to identify which giant arborvitae cultivars consistently outperform others in real-world conditions.
After reviewing dozens of offerings across multiple seasons, I’ve compiled a data-driven list of the top-performing options to help you select the giant arborvitae tree that will anchor your landscape for decades.
How To Choose The Best Giant Arborvitae Tree
Giant arborvitae cultivars vary significantly in mature height, width, growth rate, and cold tolerance. The wrong pick for your zone or space leads to stunted growth, winter burn, or a hedge that outgrows its allotted room within a few seasons. Focus on these four factors before you buy.
Cultivar Selection: Green Giant, American Pillar, or Emerald Green
The Thuja Green Giant (a hybrid of T. plicata and T. standishii) is the most aggressive grower, adding 3 to 5 feet per year once established and reaching 50-60 feet tall with a 12-20 foot spread. American Pillar (Thuja occidentalis ‘American Pillar’) grows narrowly at 3-4 feet wide and reaches 20-30 feet, making it ideal for tight side-yard screens. Emerald Green (Thuja occidentalis ‘Smaragd’) stays compact at 12-15 feet with a 3-4 foot spread — better for accent planting than full privacy walls. Match the growth habit to your available width and desired final height.
Zone Hardiness and Winter Survivability
Most giant arborvitae thrive in USDA zones 3 through 8, but winter burn and desiccation are common when a cultivar is pushed to the edge of its cold tolerance. Green Giant is reliably hardy to zone 5. American Pillar and Emerald Green handle zone 3 cold well but can suffer in zone 8 heat without afternoon shade. Always cross-reference the hardiness zone on the product listing with your local climate data — a zone mismatch is the leading cause of tree loss in the first winter.
Root System Condition and Container Size
A tree in a #3 container (3-gallon) has a more developed root mass than a quart pot, translating to faster establishment and less transplant shock. Bare-root trees require immediate planting and careful watering, while potted trees offer more flexibility. Check customer photos for root-bound indicators or sparse root systems — both signal future growth struggles regardless of top height.
Spacing and Long-Term Maintenance Expectations
For a dense privacy hedge, space Green Giant at 5-6 feet apart, American Pillar at 2.5-3 feet apart, and Emerald Green at 3-4 feet apart. Wider spacing saves money on plants but delays full coverage by 1-2 seasons. All giant arborvitae benefit from a balanced 10-10-10 or 13-13-13 fertilizer application in spring and fall, plus consistent deep watering during the first two growing seasons.

In‑Depth Reviews
1. Perfect Plants Thuja Green Giant 2ft. Tall 8-Pack
The Thuja Green Giant hybrid is the gold standard for rapid privacy screening, and this 8-pack from Perfect Plants arrives as 2-foot-tall starts ready to establish in zones 5-9. The dense, dark green foliage releases a classic Christmas-tree scent when brushed, and the pyramidal growth habit reaches 50 feet at maturity with a 20-foot spread. Owners report that the packaging — plastic wrap, paper base, and thick corrugated boxes — protects the trees even during cross-country shipping, with most arrivals showing intact root systems and no broken leaders.
Multiple verified buyers noted that not every tree in the pack hits exactly 2 feet, but the root development is uniformly strong, and the trees establish quickly with regular watering. The wide-bottomed shape provides excellent coverage for privacy screens, and the trees tolerate pruning if you need to control ultimate size. A handful of owners have successfully grown these in partial shade, though full sun produces the densest foliage.
The main drawback is the initial investment — buying an 8-pack at this tier costs more upfront than smaller alternatives. Additionally, the Green Giant’s mature width of 12-20 feet means it requires generous spacing (5-6 feet apart for a hedge) and is not suitable for narrow side-yard plantings. For large properties where rapid coverage is the goal, this cultivar remains the most reliable choice on the market.
What works
- Fastest growth rate among arborvitae (3-5 ft/year after establishment)
- Excellent packaging prevents shipping damage
- Dense foliage provides year-round privacy screening
- Tolerates a wide range of soil conditions once established
What doesn’t
- Requires ample space (12-20 ft mature width)
- Not hardy below zone 5 — winter burn risk in colder zones
- Premium price per tree compared to smaller starts
2. Brighter Blooms Emerald Green Arborvitae, 5-6 ft.
For buyers who want immediate visual impact rather than waiting years for small starts to mature, the Brighter Blooms Emerald Green Arborvitae arrives at 5-6 feet tall — already a substantial landscape presence. The narrow, pyramidal form reaches 12 feet at maturity with a tidy 3-4 foot spread, making it ideal for tight foundation plantings, entrance accents, or smaller privacy screens where Green Giant would be too wide. The deep emerald color holds well through winter without the bronze tinge common in other cultivars.
Customer feedback emphasizes the seller’s responsive replacement policy — multiple buyers reported that damaged or failed trees were replaced promptly after contact. The trees adapt to varying soil types and weather extremes, though they perform best with moderate watering and afternoon shade in warmer zones. Shipping restrictions apply to AK, AZ, HI, and OR due to federal regulations, so confirm eligibility before ordering.
The primary concern is value — at this height and price point, some buyers found larger, fuller specimens at local garden centers for less. The 30-day warranty window also drew criticism since root establishment typically takes longer than a month. For those who prioritize instant height and a proven replacement guarantee over raw dollar-per-inch metrics, this option delivers dependable results.
What works
- 5-6 ft starting height provides immediate landscape presence
- Narrow 3-4 ft spread fits tight spaces
- Responsive customer service with replacement support
- Year-round color without winter bronzing
What doesn’t
- 30-day warranty may not cover extended establishment period
- Higher cost per inch compared to big-box alternatives
- Not shippable to several western states
3. Greenwood Nursery American Pillar Arborvitae, 2x Quart Pots
Thuja occidentalis ‘American Pillar’ fills the gap between the towering Green Giant and the compact Emerald Green, reaching 20-30 feet tall with a narrow 3-4 foot spread. Greenwood Nursery ships two quart-pot starts that owners consistently describe as among the healthiest they have received from any online nursery. The growth rate is genuinely fast — multiple buyers reported 3 feet of vertical gain per year after the first season, with spacing of 2.5-3 feet producing a solid hedge within 2-3 years.
The company’s packaging protocol includes craft paper sleeves for potted plants, corrugated boxes with crunched paper stabilization, and a 14-day guarantee against transit damage. Verified reviews highlight the careful root inspection and hydration gel used on bare-root items. One bulk buyer ordered over 50 trees and reported that every single one arrived in excellent condition and grew inches within weeks.
The only significant negative came from a buyer who received a bare-root tree with no foliage and encountered a difficult return process requiring UPS drop-off. This appears to be an outlier given the overwhelming positive feedback, but the 14-day guarantee window is shorter than some competitors offer. For budget-conscious buyers who want fast, narrow growth without paying premium prices, this two-pack delivers exceptional genetic quality per dollar spent.
What works
- Outstanding genetic quality and root health reported consistently
- Narrow 3-4 ft spread ideal for tight hedge rows
- Fast growth rate (3 ft/year) after first season
- Excellent packaging with craft paper and corrugated stabilization
What doesn’t
- 14-day guarantee is shorter than industry average
- Quart pots are small — requires patience for first year
- Occasional bare-root quality inconsistency reported
4. Green Promise Farms Emerald Green Arborvitae #3 Container
Green Promise Farms offers the classic Thuja occidentalis ‘Smaragd’ in a #3 container (3-gallon), providing a more developed root system than quart or pint pots. The mature size of 18-20 feet tall with a 5-6 foot spread makes this Emerald Green cultivar suitable for moderate-height privacy hedges and specimen plantings in zones 3-8. The upright, narrow growth habit with rich emerald foliage is the same reliable form that has made Smaragd a landscaping staple for decades.
Buyers consistently praise the healthy condition upon arrival — even boxes that arrived slightly crushed contained bright green, undamaged trees. Multiple customers purchased 10 or more units across separate orders and reported uniform quality, good stem structure, and successful establishment. The 3-gallon container gives these a head start over smaller pots, reducing the time needed to reach privacy-screen height.
The most common critique is that the trees appear smaller than expected for the container size, with some buyers noting that the top growth is modest relative to the root ball. This is typical for Smaragd — they are slower growers than Green Giant, adding roughly 1-2 feet per year. The moderate growth rate means less pruning but also slower coverage for impatient landscapers. For zone 3 hardiness and a classic columnar form, this is a dependable mid-range option.
What works
- 3-gallon container provides established root system
- Hardy down to zone 3 — excellent cold tolerance
- Classic emerald color holds through winter
- Consistent quality across multiple orders
What doesn’t
- Slower growth rate (1-2 ft/year) compared to Green Giant
- Top growth may appear small relative to container size
- Limited to 18-20 ft height — not suitable for taller screens
5. SimplyGro Fertilizer Spikes for Evergreen Trees, 24-Pack
Proper nutrition is often the missing link between a giant arborvitae that struggles and one that thrives, and the SimplyGro 12-3-3 fertilizer spikes provide a set-it-and-forget-it solution. Each 5-inch spike delivers continuous feeding for up to 3 months, targeting the high nitrogen demand that evergreens require for lush foliage and vigorous growth. The pre-measured format eliminates the risk of over-fertilization and nutrient runoff that can occur with granular applications.
Customer reviews are overwhelmingly positive, with several owners reporting dramatic recovery of trees that were on the verge of death from nitrogen deficiency. One buyer noted that their sandy soil leached nitrogen rapidly, and these spikes kept their trees lush and green for 4-5 months even with frequent watering. The patented TruSpike design is significantly more durable than old-style crumbly spikes — they hammer in without breaking, requiring no plastic cap or special tools.
The spikes are most effective when applied twice per year (spring and fall), meaning a 24-pack covers 12 trees for one annual cycle. They work well for all evergreens including pines, firs, and hollies, not just arborvitae. The only limitation is that spikes concentrate nutrition at the insertion points rather than distributing evenly through the root zone — for very large mature trees, a broadcast granular fertilizer may provide more uniform coverage.
What works
- 12-3-3 NPK ratio optimized for evergreen nitrogen needs
- Pre-measured spikes prevent over-fertilization
- Durable TruSpike design won’t break during installation
- Effective for 3 months per application with no runoff
What doesn’t
- Concentrates nutrition at insertion points
- 24 spikes covers 12 trees for one year — buy multiple packs for larger hedges
6. Sandys Nursery Thuja Green Giant Arborvitae, Lot of 50, 3 Inch Pot
For large-scale projects like property border screens, windbreaks, or commercial landscaping, Sandys Nursery’s lot of 50 Thuja Green Giant starts offers the most cost-effective path to mass coverage. Each tree ships in a 3-inch deep pot with soil and stands 10+ inches tall at delivery. The Green Giant genetics promise 3-5 feet of annual growth once established, with mature dimensions of 30-50 feet tall and 12-16 feet wide — ideal for spacing 5 feet apart in a hedge row.
Long-term customer reviews are remarkable — one buyer updated their experience over 8 years, reporting that after losing roughly 4 of 30 trees from the initial planting, the survivors reached over 7 feet tall by year seven and continue to thrive. Packaging is thorough, with each tree individually bagged to retain moisture, and multiple buyers confirmed that all 50 plants arrived green, healthy, and ready for immediate planting. The hybrid vigor of T. plicata x T. standishii provides excellent drought tolerance once the root system matures.
The main consideration is that these are small starter plants — 10 inches tall — requiring patience, proper soil preparation, and consistent watering for the first two seasons. The lot of 50 also represents a significant commitment of labor and planting space. A small percentage of buyers reported minor losses during shipping, though the overwhelming consensus is that the value per tree at this volume is unmatched by any local nursery.
What works
- Exceptional value per tree at bulk quantity
- Proven long-term performance over 8+ years
- Hybrid genetics provide fast growth and drought tolerance
- Individual packaging keeps roots moist during transit
What doesn’t
- Small starter size (10 inches) requires 2-3 seasons to reach privacy height
- Significant labor investment for planting 50 trees
- Not shippable to Arizona
7. Artificial Home Decor 6 ft Pre-Potted Cedar Tree, 2-Pack
Not every situation calls for a live tree — rental properties, covered patios, indoor atriums, and commercial spaces with low light or strict HOA rules may benefit from the Artificial Home Decor 6-foot pre-potted cedar. The UV-resistant coating prevents fading in direct sun, keeping the foliage vibrant through all seasons without any watering, pruning, or fertilizing. Assembly requires no tools: unpack, set the pot, and arrange the branches to your desired fullness.
Buyers consistently report that the realism is convincing enough to draw questions from visitors — one owner noted that guests asked whether the tree was real. The 2-pack configuration works well for symmetrical entryway framing, and the 20-inch pot diameter provides stable support even in outdoor wind conditions. Multiple customers confirmed the trees weathered snow storms without damage, demonstrating reasonable construction quality for the price point.
The most common complaint is that the included pot feels lightweight and less sturdy than expected, with one delivery arriving with a cracked base. Several owners solved this by dropping the pot into a heavier decorative container and adding stones for stability. The branch material is plastic, and aggressive shaping can cause breakage. For buyers who need instant, maintenance-free greenery in locations where live arborvitae would struggle, this artificial alternative delivers reliable aesthetics without the horticultural learning curve.
What works
- UV-resistant coating prevents fading in direct sunlight
- Realistic appearance — passes the “is it real?” test
- Zero maintenance: no watering, pruning, or fertilizing
- Easy tool-free assembly
What doesn’t
- Pot base feels lightweight and may need reinforcement
- Plastic branches can break if bent aggressively
- Not a substitute for living air-purification or ecological benefits
Hardware & Specs Guide
USDA Hardiness Zone
The zone rating indicates the coldest temperatures a cultivar can survive. Green Giant is reliable in zones 5-8 but struggles below -20°F. American Pillar and Emerald Green handle zone 3 cold (-40°F) but may suffer heat stress in zone 8 summers. Always match the zone number on the plant tag to your local USDA zone — pushing a zone 5 tree into zone 4 winter conditions often results in dieback or total loss.
Growth Rate and Mature Dimensions
Green Giant leads at 3-5 feet per year after establishment, reaching 50-60 feet tall with a 12-20 foot spread. American Pillar adds 2-3 feet per year and tops out at 20-30 feet tall with a 3-4 foot spread. Emerald Green grows 1-2 feet per year and matures at 12-15 feet. These numbers determine both how quickly your privacy screen fills in and how much pruning you will eventually need to manage.
Container Size and Root Volume
A #3 container holds 3 gallons of soil and supports a root ball roughly 10-12 inches in diameter. Quart pots hold 1 quart — a quarter of the volume — and produce smaller root systems that require more careful watering during the first season. Larger containers reduce transplant shock and accelerate establishment by providing more stored moisture and nutrients. Bare-root trees offer the smallest initial root mass but the lowest shipping weight.
Sun Exposure and Soil Preferences
All giant arborvitae perform best in full sun (6+ hours of direct light daily), which produces the densest foliage. Partial shade is tolerated but results in looser growth and slower coverage. Well-drained soil with a pH between 6.0 and 8.0 is ideal. Heavy clay soils require amendment with compost or sand to prevent root rot. Sandy soils need more frequent watering and benefit from supplemental fertilization as nutrients leach quickly.
