A bare fence line or exposed property edge isn’t just a view issue — it’s a constant loss of privacy and a sound tunnel from your neighbor’s yard. The right upright shrub can transform that open boundary into a living wall, blocking sight lines and dampening noise while adding structure and seasonal color to your landscape.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years studying nursery stock data, measuring mature growth rates, comparing root system hardiness, and cross-referencing regional climate success rates for hundreds of upright shrub varieties in the market.
This analysis breaks down the top candidates for vertical screening, dense hedging, and rapid filling of empty space, making it easy to choose the best bushes that grow tall for your specific zone and sun exposure.
How To Choose The Best Bushes That Grow Tall
Selecting a tall-growing shrub requires more than picking the tallest option at the nursery. You need to consider your local climate, the plant’s mature spread, its growth rate per year, and whether it stays evergreen or drops leaves in winter. A fast vertical grower in one zone can stall in another.
Mature Height vs. Growth Rate
Two different metrics often get confused. A shrub listed with a 15-foot mature height might take 20 years to get there. A bush that grows 3 feet per year can reach 12 feet in four years. Always check the annual growth rate in inches or feet, not just the final height estimate.
Evergreen vs. Deciduous for Year-Round Screening
If you need privacy in winter, choose an evergreen like Thuja Green Giant. Deciduous tall shrubs like Spirea provide beautiful flowers in spring and summer but leave bare branches from late fall through early spring, exposing your view during the coldest months.
Spacing and Spread at Ground Level
A plant that grows 30 feet tall but spreads 15 feet wide will demand a lot of horizontal space. For narrow side yards or tight boundary lines, look for columnar or upright varieties with a spread under 6 feet. Check the recommended spacing — 2 to 3 feet between plants creates a dense hedge, while wider spacing leaves gaps.

In‑Depth Reviews
1. 18 Hybrid Willow Trees
Hybrid willows are the sprinters of the tall-shrub world, pushing 3 to 5 feet of vertical growth per year once their roots establish. This 18-count bundle gives you enough material to line a long fence or create a dense visual barrier in a single season. The trade-off is their deciduous nature — leaves drop in winter, reducing privacy temporarily.
These trees thrive in moist soil and full sun, making them ideal for low-lying areas or spots near a water source. They also tolerate heavy pruning, allowing you to shape them into a hedge form or let them grow into a more natural multi-stem screen. The included growing tutorial video helps beginners avoid common planting-depth mistakes.
Because they grow so fast, expect to trim at least once a year to keep them from overwhelming a narrow space. Their root systems are vigorous too, so avoid planting near underground pipes or septic fields. For sheer speed of coverage, very few options match this willow bundle.
What works
- Annual growth of 3-5 feet provides near-instant screening
- 18 trees per pack covers long stretches affordably
What doesn’t
- Fully deciduous — no winter privacy cover
- Aggressive roots can damage underground utilities over time
2. Brighter Blooms Thuja Green Giant Arborvitae 2-3 ft
Thuja Green Giant is the gold standard for tall evergreen screening, and this 2-3 foot starter from Brighter Blooms is ready to rocket upward. Once settled, these trees gain 3 to 5 feet in height per year, eventually reaching 50 to 60 feet at full maturity. The dense, fan-like foliage stays green year-round, offering total privacy even in deep winter.
This variety is notably deer resistant, which is a major advantage in rural or suburban areas where browsing animals can destroy younger plantings. It also tolerates a wide range of soil types, including sandy and clay, and requires no pruning to maintain its symmetrical pyramid shape. Just plant it in full sun and water moderately during dry spells.
One important note: this item ships as a live plant with a root system already developing, so you lose the risk of starting from a bare root. The warranty covers delivery damage, giving you peace of mind for an investment that will define your landscape for decades. Shipping restrictions apply to AK, AZ, HI, and OR.
What works
- Evergreen foliage delivers year-round screening
- Deer resistant and adaptable to sandy or clay soils
What doesn’t
- Cannot ship to AK, AZ, HI, or OR
- Mature spread of 12-15 feet requires generous spacing
3. 10 Thuja Green Giant Arborvitae 7-10 inches Tall Trees
This 10-pack of small Thuja Green Giant starts at 7-10 inches tall, giving you a budget-friendly foundation for a long hedge row. Because these are young trees, you avoid the transplant shock that sometimes hits larger potted nursery stock. The root systems adapt quickly to your soil, and within two growing seasons, these tiny starts will double or triple in height.
The Green Giant genetics are identical to the larger 2-3 foot version — same 3-5 foot annual growth rate, same deer resistance, same evergreen foliage. The main difference is time to maturity. You will need to be patient during the first year, but the cost savings per tree make it feasible to plant a dense staggered row that naturalizes into a solid wall within four or five years.
Space these trees 5 to 6 feet apart for a dense hedge, or 8 to 10 feet for isolated specimen planting. Water them regularly during the first summer and mulch the base to retain moisture. For anyone planning a long privacy border on a tighter upfront budget, this bulk option maximizes coverage per dollar spent.
What works
- 10 young trees per pack for a long hedge row on a budget
- Same fast-growing genetics as larger Green Giants
What doesn’t
- Requires 2-3 years of patience before significant height appears
- Small starter size is vulnerable to weeds and foot traffic
4. Proven Winners Double Play Doozie Spirea
Double Play Doozie Spirea offers a more modest upright stature, topping out at 24-36 inches tall and wide, but it delivers continuous color from spring through fall. The red-to-purple flowers appear on new wood, so deadheading is unnecessary to keep the show going. This is a great option for the front of a mixed border or as a low hedge accent rather than a full privacy screen.
Customer feedback consistently praises the size and health of these 2-gallon pots on arrival. Multiple buyers note the plants were full, with russet tips and active blooms already showing. The Spirea thrives in USDA zones 3-8 and accepts full sun to partial shade, making it one of the most adaptable compact shrubs in this lineup.
Keep in mind this is a deciduous plant that loses foliage in winter. If you are looking for a low-maintenance flowering bush to fill the mid-layer of a tall border, this Spirea excels. But it will not serve as a standalone privacy barrier due to its limited mature height.
What works
- Non-stop blooms from spring to fall with zero deadheading
- Plants arrive in excellent condition with healthy root systems
What doesn’t
- Mature height of only 24-36 inches limits screening use
- Loses all foliage in winter; bare stems remain
5. Pugster Buddleia True-Blue Flowers
Pugster Buddleia, known commonly as a dwarf butterfly bush, tops out at 24-30 inches wide and 24 inches tall. While it is not a tall screening plant, its dense branching and large true-blue flower panicles make it a standout specimen for pollinator gardens. The fragrance and nectar draw bees, butterflies, and hummingbirds throughout its long bloom season from spring to fall.
This Proven Winners selection thrives in USDA zones 5-9 and prefers full sun to part shade. It ships dormant through early spring, meaning you may receive bare stems that leaf out after planting. The 2-gallon size gives you a head start compared to smaller plugs, and the organic material feature means no synthetic chemicals were used during propagation.
If your goal is to add vertical interest to a mixed border while supporting local pollinator populations, this Buddleia delivers. Just remember that it will not provide privacy or shade. It works best as a colorful mid-layer or accent in front of taller evergreens.
What works
- Large true-blue flowers attract butterflies and hummingbirds
- Compact form fits small garden beds without crowding
What doesn’t
- Mature height is only 24 inches — not a tall bush
- Ships dormant with no foliage; requires patience for first flush
Hardware & Specs Guide
Growth Rate
The most critical number for vertical screening is annual vertical growth. Fast-growing options like Hybrid Willow and Thuja Green Giant add 3-5 feet per year. Slower varieties like Spirea and Buddleia grow only a few inches yearly after establishment. Always verify growth rate per season, not just mature height, to set realistic expectations for your timeline.
Mature Spread
A bush that grows tall but spreads wide can crowd a narrow corridor. Hybrid Willows and Thuja Green Giants have a mature spread of 12-15 feet, requiring 5-8 feet of clearance from structures. Compact options like Spirea and Buddleia spread only 2-3 feet, making them suitable for tight foundation plantings or small urban yards.
