Emerald Green Arborvitae height by variety: mature sizes compared
When planning your landscape, choosing the right Emerald Green Arborvitae variety makes all the difference. The classic Emerald Green Arborvitae typically reaches 12–15 feet tall at maturity, but some faster-growing varieties can top 40 feet. Understanding these differences helps you select the perfect fit for your space—whether you need a privacy screen or a hedge border.
The growth rate also varies widely. Some varieties grow just 12 inches per year, while others can shoot up 24 inches annually. This means your 5-year-old Arborvitae could range from 6 feet to 12 feet tall, depending on the variety. Proper spacing is key to avoiding overcrowding and ensuring each plant thrives.
Here’s how the top 5 fastest-growing Emerald Green Arborvitae varieties compare in terms of mature height, growth rate, and ideal spacing for full coverage:
| Variety | Mature Height | Growth Rate (per year) | Ideal Spacing | Best For |
|---|---|---|---|---|
| Emerald Green (Standard) | 12–15 ft | 12–18 in | 3–5 ft apart | Hedges, privacy screens |
| Emerald Sentinel | 15–20 ft | 18–24 in | 5–7 ft apart | Tall privacy screens |
| Emerald Spire | 25–30 ft | 24 in | 8–10 ft apart | Large property borders |
| Emerald Green Compact | 6–8 ft | 6–12 in | 2–3 ft apart | Small gardens, containers |
| Emerald Green Giant | 40+ ft | 24–36 in | 12–15 ft apart | Massive privacy barriers |
If you’re planting for a privacy screen, the Emerald Green Giant or Emerald Spire will give you the fastest coverage. For a smaller landscape, the Compact variety stays manageable while still offering year-round greenery. Always check your local climate zone—some varieties thrive better in USDA Zone 5 than others.
Proper spacing is critical. Planting Emerald Green Arborvitae too closely can lead to overcrowding, stunted growth, or even disease. For example, the Standard variety needs 3–5 feet between plants, while the Giant variety requires 12–15 feet to avoid competition for nutrients and water.
Another key factor is sunlight exposure. These evergreens thrive in full sun (6+ hours daily), but they can tolerate partial shade in hotter climates. If you’re in a shady area, opt for the Compact variety, as it handles lower light better than taller types.
For fastest growth, focus on well-draining soil and consistent moisture during the first year. Mulching around the base helps retain moisture and regulates soil temperature. Avoid overwatering, as soggy roots can lead to root rot—a common issue with Arborvitae.
Pruning is another way to control height. If you notice your Emerald Green Arborvitae growing too tall, trim the top 1/3 of new growth in early spring. This encourages bushier growth and keeps the plant within your desired height limits. Just avoid heavy pruning in late summer or fall, as this can stress the plant before winter.

Emerald Green Arborvitae height by variety: mature sizes compared
The classic Emerald Green Arborvitae typically reaches 12–15 feet tall at maturity, but several faster-growing varieties can exceed 30 feet if left unpruned. Understanding these differences helps you choose the perfect fit for your privacy screen or landscape focal point. Below, I’ve compared the most popular varieties by their mature heights and growth rates to help you plan spacing and long-term care.
For small spaces, varieties like Emerald Sentinel stay compact at 12–15 feet, while Emerald Giant towers at 30–40 feet, making it ideal for large properties or windbreaks. The key difference? Growth rate—some varieties gain 24 inches per year, while others grow just 12 inches annually. This affects how quickly you’ll achieve full coverage.
| Variety | Mature Height | Growth Rate (Annual) | Spacing for Full Coverage |
|---|---|---|---|
| Emerald Green (Standard) | 12–15 ft | 12–18 in | 3–5 ft apart |
| Emerald Sentinel | 12–15 ft | 12–15 in | 3–4 ft apart |
| Emerald Giant | 30–40 ft | 24–30 in | 8–10 ft apart |
| Emerald Spire | 15–20 ft | 18–24 in | 5–6 ft apart |
| Emerald Globe | 3–5 ft (dwarf) | 6–12 in | 2–3 ft apart |
When planning your privacy screen, the Emerald Giant is my top pick for large properties due to its rapid growth. However, if you’re working with limited space, the Emerald Sentinel or Emerald Globe (for ground cover) are far more manageable. Always check your local USDA hardiness zone—most varieties thrive in Zones 3–8, but Emerald Giant may need extra winter protection in colder climates.
Pro tip: Prune in late winter to control height and encourage bushier growth. Use sharp, clean shears and avoid cutting into old wood, which can harm the plant. For hedges, aim for 3–5 feet apart to allow airflow and reduce disease risk. If you’re planting multiple rows, stagger them to create a denser barrier faster.
For windbreaks, space Emerald Giant varieties 8–10 feet apart to maximize their natural wind-blocking abilities. Their dense foliage reduces wind speed by up to 50%, making them ideal for exposed areas. Just remember: Taller doesn’t always mean better—choose based on your property’s scale and sunlight exposure.
If you’re unsure which variety to pick, start with the Emerald Green (Standard)—it’s the most versatile for hedges and privacy screens while staying within a manageable 12–15 foot height. For a low-maintenance option, Emerald Globe is perfect for borders or container gardening.
