Exact mature heights of arborvitae by fastest-growing varieties
Arborvitae heights vary dramatically by variety, from dwarf shrubs under 3 feet to towering trees that dwarf two-story homes. The right choice depends on your space and goals—whether you need a quick privacy screen or a low-maintenance landscape accent. Here’s the breakdown of the most popular types and their mature heights.
For fast-growing arborvitae, the Leyland Cypress hybrid is the undisputed champion, while Emerald Green remains a classic for medium-sized yards. Even slow growers like 'Compacta' can be shaped into stunning hedges with proper care. Let’s dive into the specifics so you can pick the perfect fit.
🌲
| Variety | Mature Height | Width | Growth Rate | Best For |
|---|---|---|---|---|
| Green Giant (Thuja standishii x plicata) | 40–60 ft | 12–20 ft | 3–5 ft/year | Privacy screens, windbreaks |
| Emerald Green (Thuja occidentalis) | 12–15 ft | 4–6 ft | 6–12 in/year | Hedges, small yards |
| Leyland Cypress (x Cupressocyparis leylandii) | 60–70 ft | 15–25 ft | 3–5 ft/year | Fast privacy screens |
| American Arborvitae (Thuja occidentalis) | 30–40 ft | 10–15 ft | 12–24 in/year | Native landscapes |
| Compacta (Thuja occidentalis 'Compacta') | 3–8 ft | 3–5 ft | 3–6 in/year | Containers, small spaces |
| Golden Globe (Thuja occidentalis 'Aurea') | 3–5 ft | 3–5 ft | 4–8 in/year | Accent plants, borders |
The Green Giant and Leyland Cypress are the fastest-growing arborvitae, perfect if you need a quick privacy solution. Their rapid growth means they’ll fill out your landscape in just a few years, but they’ll also need plenty of space to sprawl. For smaller yards, 'Emerald Green' or 'Compacta' are ideal—they stay manageable while still offering year-round greenery.
If you’re planting for windbreaks, the American Arborvitae is a hardy native choice that grows steadily without aggressive pruning. Just remember: taller varieties need 6–10 feet of clearance from power lines and structures. Always check local regulations before planting near buildings or roads.

Pro tip: Dwarf varieties like 'Golden Globe' are perfect for containers or foundation plantings. They rarely need pruning and thrive in partial shade, making them low-maintenance stars. Meanwhile, the Leyland Cypress hybrid can grow up to 5 feet per year—so if you’re in a hurry, it’s the ultimate fast-track option.
Now that you know the heights, let’s talk growth rates—because some arborvitae shoot up like weeds, while others take their time. Which one will fit your timeline?
How fast arborvitae grow: annual growth rates by type
If you’re wondering how fast arborvitae grow, the answer depends entirely on the variety—some shoot up like weeds while others take their time. For example, the Leyland Cypress can add 3–5 feet per year, while 'Emerald Green' grows a modest 6–12 inches annually. Understanding these growth rates helps you plan for quick privacy screens or patiently nurture a slow-growing accent plant.
Growth speed also depends on soil quality, sunlight exposure, and watering consistency. A well-drained, nutrient-rich soil with 6+ hours of sun daily can double or triple growth rates in fast varieties. Meanwhile, dwarf arborvitae like 'Compacta' thrive in partial shade and grow just 3–6 inches per year, making them perfect for containers or tight spaces.

The Leyland Cypress is the undisputed fastest-growing arborvitae, ideal if you need a quick privacy hedge. In just 5 years, it can reach 25–30 feet tall, providing instant screening. For slower but steady growth, 'Green Giant' is a balanced choice, offering 3–4 feet per year without the aggressive spread of Leyland Cypress.
If you’re working with limited space, dwarf varieties like 'Compacta' or 'Golden Globe' grow at a leisurely pace, making them easier to manage. Their slow growth also means they’re low-maintenance—perfect for busy gardeners or small urban yards. Just remember: even slow growers need proper spacing to avoid overcrowding.

To maximize growth, focus on well-draining soil, consistent moisture, and annual pruning to encourage bushier growth. Avoid overwatering, as soggy soil can stunt growth or invite root rot. With the right care, even the slowest arborvitae will thrive—and the fastest growers will become your landscape’s star attraction in no time.
Now that you know the growth rates, let’s talk about how to choose the right variety for your space—because not every arborvitae fits every yard!
