Choosing the perfect evergreen for your landscape can be a daunting task, especially when faced with similar-looking options like the Emerald Green and Green Giant arborvitae. Both offer stunning vertical accents, but their subtle differences can significantly impact their suitability for your specific needs and space. This comprehensive guide will help you understand the key distinctions between these two popular choices, enabling you to make an informed decision.
What are the key differences between Emerald Green and Green Giant Arborvitae?
The most significant differences between Emerald Green and Green Giant arborvitae lie in their growth rate, mature size, and overall shape. While both are columnar evergreens prized for their vibrant green foliage, their characteristics diverge enough to warrant careful consideration.
Growth Rate: A Tale of Two Speeds
The Green Giant arborvitae is renowned for its impressively fast growth rate. Expect to see significant height increases year after year, making it a popular choice for those seeking rapid screening or a quick visual impact. Conversely, the Emerald Green arborvitae is a much slower grower, offering a more gradual and controlled expansion.
Mature Size: Planning for the Future
The difference in growth rate directly translates to mature size. A mature Green Giant can reach towering heights of 50-60 feet (15-18 meters) with a width of 10-15 feet (3-4.5 meters). This makes it unsuitable for smaller gardens or areas with limited space. The Emerald Green, on the other hand, matures at a much more manageable 15-20 feet (4.5-6 meters) tall and 3-5 feet (0.9-1.5 meters) wide.
Shape and Density: Aesthetic Considerations
While both boast a columnar shape, there are subtle differences. The Green Giant tends to have a slightly broader base and a more tapered top, giving it a slightly less formal look. The Emerald Green maintains a tighter, more uniformly columnar shape throughout its height, making it ideal for formal landscapes or hedges. Both have dense foliage, providing excellent screening and privacy.
What are the pros and cons of Emerald Green Arborvitae?
Pros:
- Slower growth: Requires less frequent pruning and maintenance.
- Smaller mature size: Suitable for smaller gardens and tighter spaces.
- Denser, more formal shape: Creates a more structured, polished look.
- Excellent screening: Provides effective privacy.
- Relatively low maintenance: Once established, it requires minimal care.
Cons:
- Slower growth: Takes longer to achieve desired height and screening effect.
- More expensive per unit: Because of their slower growth rate, established plants can cost more.
What are the pros and cons of Green Giant Arborvitae?
Pros:
- Fast growth: Quickly establishes a screen or windbreak.
- Dramatic visual impact: Makes a statement in the landscape quickly.
- Strong and hardy: Tolerates a range of conditions.
- Excellent screening: Provides effective privacy.
- Relatively disease resistant: Generally healthy and low maintenance.
Cons:
- Fast growth: Requires more frequent pruning to maintain shape.
- Large mature size: Not suitable for small gardens.
- Can become top-heavy: Might require staking, especially in windy areas.
- More expensive per unit: The faster growth doesn't mean they're inexpensive.
Which Arborvitae is better for privacy screening?
Both Emerald Green and Green Giant arborvitae excel as privacy screens. The choice depends on your timeframe and space constraints. If you need rapid screening, the Green Giant's faster growth is advantageous. However, if you have limited space or prefer a more controlled, slower-growing option, the Emerald Green is a better fit.
Which Arborvitae is easier to care for?
The Emerald Green arborvitae is generally considered easier to care for due to its slower growth rate, requiring less frequent pruning. The Green Giant, while still relatively low-maintenance, needs more regular pruning to maintain its shape and prevent it from becoming overly large.
Which Arborvitae grows taller?
The Green Giant Arborvitae grows significantly taller than the Emerald Green, reaching heights of 50-60 feet compared to the Emerald Green's 15-20 feet.
Which Arborvitae is best for small spaces?
The Emerald Green Arborvitae, with its much smaller mature size, is the better choice for smaller spaces. The Green Giant's large mature size makes it unsuitable for smaller gardens or yards.
By carefully weighing the pros and cons of each variety and considering your specific landscape needs, you can confidently select the perfect arborvitae—whether Emerald Green or Green Giant—to enhance the beauty and functionality of your outdoor space. Remember to consult with local nurseries or arborists for advice tailored to your region's climate and soil conditions.
