thuja occidentalis smaragd height

How Tall Does Thuja occidentalis ‘Smaragd’ Grow?

The Thuja occidentalis ‘Smaragd’ height at maturity is one of its most appealing features. In New Zealand gardens, this slow-growing evergreen typically reaches between 3 to 4 metres tall and 75 centimetres to 1 metre wide over 10 to 15 years. Its naturally conical shape means it rarely needs pruning to maintain its tidy, formal silhouette.

If you’re seeking a living screen or attractive boundary that won’t overtake smaller spaces, the manageable Thuja occidentalis ‘Smaragd’ height makes it a top choice. It’s also a fantastic low-maintenance alternative to faster-growing, larger conifers for gardens where space is at a premium.

Planting and Spacing for Best Results

When planning a hedge, plant your ‘Smaragd’ thujas about 60 to 90 centimetres apart. This ensures each tree has enough space to reach its optimum height and spread, forming a dense, lush barrier. They thrive in well-drained soils and both full sun or partial shade, although you’ll see the best colour and compact growth in sunnier spots.

Comparisons to Other Thuja Varieties

If you’re weighing your options for hedging conifers, it’s helpful to compare the Thuja occidentalis ‘Smaragd’ height with other popular arborvitae and conifers:

• The Thuja occidentalis 'Pyramidalis' offers a similar upright habit but can reach slightly taller heights, up to 5 metres.
• For those seeking a larger, faster-growing variety, the Thuja 'Green Giant' excels, shooting up over 10 metres—ideal for big properties.
• Thuja plicata and its golden cousin, Thuja plicata Old Gold (Thuja Old Gold), are both larger west coast conifers, known for vigorous growth and robust hedging ability.
• Those after a more compact, decorative option might enjoy the golden-tipped Thuja occidentalis 'Rheingold', which stays low and rounded.

Alternatives for Structure and Colour

In addition to Thujas, there are many excellent conifers for contrasting form and colour in your garden design. Consider the rich gold foliage of Cupressocyparis Castlewellan Gold, the striking blue tones of Cupressus Blue Ice (Blue Arizona Cypress), the classic conical shape of Picea abies Pyramidalis, or the graceful weeping habit of Cedrus deodara.

Summary

In summary, the Thuja occidentalis ‘Smaragd’ height makes it ideal for urban hedging, driveway borders, or neat specimen planting in New Zealand landscapes. Its combination of vibrant colour, compact growth, and minimal maintenance ensures year-round beauty in any garden.
