Waiting years for a privacy screen or a tropical corner to fill in is the single biggest pain in landscaping. You want height this season, not next decade. The right genetics change the timeline from a slow crawl to a visible weekly gain, turning bare soil into a living wall or a canopy in one growing cycle.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. My approach relies on cross-referencing growth rate data from horticultural databases with thousands of verified owner experiences to separate true fast-growers from overhyped nursery stock.
This guide breaks down five proven selections that deliver vertical momentum fast, from tropical indoor showstoppers to outdoor privacy powerhouses. Whether you are screening a property line or filling a tall corner inside your home, the best fast growing tall plants share one trait: they pack on measurable inches every week if given the right conditions.
How To Choose The Best Fast Growing Tall Plants
Not every tall plant grows fast, and not every fast grower gets tall. The overlap is where the real value lives. You need to match the growth habit to your specific light, space, and climate constraints or the plant stalls.
Indoor versus Outdoor Growth Potential
Indoor tall plants like the White Bird of Paradise or Majesty Palm top out around ceiling height in a container, but their vertical pace slows once root-bound. Outdoor species like the Thuja Green Giant or Hybrid Willow keep accelerating for years because the root system is unrestricted. Decide where the final home is before picking.
Annual Growth Rate vs Mature Height
A plant that grows 10 feet per year but only tops at 15 feet stops being useful quickly. The Hybrid Willow can hit 10 feet annually and keeps climbing to 50-plus feet, making it a true long-term privacy investment. Check both the “inches per season” claim and the “mature height” number before committing.
Maintenance and Space Demands
Fast growth demands resources. These plants require consistent watering, regular feeding, and often aggressive pruning if the spread exceeds your space. The Ficus Weeping Fig looks grand indoors but drops leaves if you move it. The Hybrid Willow needs a wet area or consistent irrigation. Factor in your weekly care capacity.

In‑Depth Reviews
1. 50 Hybrid Willow Trees
The Hybrid Willow from CZ Grain is the standout for raw vertical speed. These bare-root saplings are marketed as the fastest-growing trees on the planet, with verified reports of 10 feet of new growth per year in good soil and consistent moisture. At this price for 50 live plants, the per-unit cost is remarkably low, making it the most aggressive privacy-screen option on this list by a wide margin.
These trees are specifically suited for erosion control, bog drying, and quick screening. They are deciduous, so they drop leaves in winter, but the bare branch structure still provides visual blocking. The package includes detailed planting instructions and a YouTube tutorial, which is important because bare-root trees need proper soaking and staking in the first season.
Be prepared for serious space requirements. Mature height can exceed 50 feet with a spread of 15 to 20 feet, so planting them too close to structures or underground pipes is a common mistake. They also demand wet feet — the Willow family thrives in consistently damp soil, not dry clay or sand.
What works
- Unmatched annual growth rate of 10 feet per year
- Excellent for privacy, windbreak, and erosion control
- Deer resistant and produces no seeds or cotton
What doesn’t
- Needs consistently wet soil — not drought tolerant
- Deciduous — loses leaves in winter
- Massive mature spread limits planting distance
2. Thuja Green Giant Arborvitae
The Thuja Green Giant is the top choice for anyone who wants a dense evergreen screen that stays green through every season. These 7-10 inch starter plugs hit 3 to 5 feet of growth per year once established, and they mature at 50 to 60 feet tall with a compact 12-15 foot spread, making them far more space-efficient than the Willow.
Unlike the Willow, the Green Giant does not demand wet soil. It thrives in average, well-drained soil and handles heat, humidity, and even mild drought once the root system is deep. This adaptability makes it the more predictable option for homeowners who do not want to babysit their privacy screen with constant irrigation.
The trade-off is patience. While 3 to 5 feet per year is fast, it is not the immediate wall that the Hybrid Willow provides. You need to plant these at least 5 feet apart (4 feet for a tighter hedge) and wait for the second and third growing seasons to see the real density fill in.
What works
- Evergreen — provides year-round dense privacy
- Resistant to deer, disease, and most pests
- Grows well in average soil without constant watering
What doesn’t
- Slower initial growth compared to Hybrid Willow
- Starter plugs arrive small and need careful first-year care
- Spacing requires planning to avoid overcrowding
3. White Bird of Paradise
The White Bird of Paradise shipped by United Nursery arrives at 32 to 36 inches tall in a 10-inch pot, giving you an immediate tall presence for indoor spaces. The Strelitzia Nicolai species produces paddle-shaped leaves that can reach 18 inches wide, creating a bold tropical silhouette that fills a corner or living room division point within the first year.
This plant grows quickly indoors if it receives bright, indirect light and consistent watering. The growth is vertical and architectural — each new leaf emerges from the center and towers above the older ones. Indoor height can reach 6 to 8 feet in a container, which is a strong vertical gain for an indoor species that does not require grow lights.
The catch is that this plant is a heavy drinker and feeder. It needs watering when the top inch of soil dries, plus monthly fertilizer during the growing season. Expect leaf browning if humidity drops below 40 percent, especially in heated winter homes.
What works
- Arrives already tall at 32-36 inches
- Dramatic tropical foliage with large paddle leaves
- Fast vertical growth under bright indoor light
What doesn’t
- Needs high humidity and consistent moisture
- Susceptible to leaf tip burn in dry air
- Outgrows a 10-inch pot quickly — plan to repot
4. Wintergreen Weeping Fig Tree
The Wintergreen Weeping Fig, a Ficus cultivar, is an excellent pick for indoor spaces that do not get direct sunlight. It arrives rooted in an 8-inch pot and establishes quickly, producing glossy, deep-green leaves that drape elegantly. It is one of the few tall indoor trees that tolerates low light without stalling.
This Ficus grows at a moderate pace — slower than the Bird of Paradise but faster than most traditional houseplants. It can reach 6 to 8 feet indoors if potted up every couple of years. The appeal is reliability: it adapts to low light, dry air, and inconsistent watering better than the Majesty Palm.
The downside is that Ficus benjamina is notorious for dropping leaves when moved. Even rotating the pot or changing its position in the room can trigger a leaf drop event. This plant needs a permanent spot and minimal disturbance to keep its full canopy.
What works
- Tolerates low light better than most indoor trees
- Glossy foliage with elegant weeping habit
- Adapts to dry indoor air without browning
What doesn’t
- Drops leaves dramatically if moved or relocated
- Moderate growth — not as fast as Bird of Paradise
- Needs consistent pot-up to continue vertical growth
5. Majesty Palm
The Majesty Palm from United Nursery offers an instant tropical presence at 32 to 36 inches tall in a decorative pot. Its arching, feather-like fronds create a soft, fountain shape that adds height without the rigid structure of the Bird of Paradise. It works well as a floor plant beside sofas or in entryways.
This palm pushes new fronds from the center regularly in warm, bright conditions, adding measurable height over the growing season. Indoor specimens can reach 6 feet or more, with the fronds cascading outward for a full, lush look. It prefers bright, indirect light and consistently moist soil.
The Majesty Palm is more sensitive than the other indoor options on this list. It struggles in low light, and its fronds brown quickly if the humidity drops or the soil dries out even once. It is not a set-and-forget plant — it demands weekly attention to maintain its fresh green look.
What works
- Arrives tall with full decorative foliage
- Fountain-shaped fronds add soft height
- Classic tropical look for floor spaces
What doesn’t
- Requires high humidity and bright light
- Fronds brown quickly if watering is missed
- Not suitable for low-light rooms
Hardware & Specs Guide
Growth Rate per Year
Annual vertical gain is the single most critical spec for fast-growing tall plants. The Hybrid Willow leads at 10 feet per year, followed by the Thuja Green Giant at 3 to 5 feet. Indoor plants like White Bird of Paradise and Majesty Palm add roughly 12 to 24 inches per year in a container. Ficus Weeping Fig is the slowest at 6 to 12 inches indoors. Always multiply the claimed rate by your growing zone and light availability.
Mature Height and Spread
Outdoor plants can reach massive sizes: Hybrid Willow hits 50+ feet tall and 20 feet wide, while Thuja Green Giant reaches 50-60 feet with a tighter 12-15 foot spread. Indoor options top out at 6 to 8 feet in containers. Spread is often ignored but equally important — planting a Willow too close to the house means root intrusion and branch overhang, while a confined pot limits the indoor height of any tall plant.
