Types of Arborvitae: Hedges, Trees, and Shrubs (With Pictures and Identification)
Arborvitaes are generally slow-growing evergreen conifers with soft, lush feathery foliage. Different types of arborvitae grow as upright columnar trees, small conical trees, or globe-shaped shrubs. Arborvitae trees and shrubs are ideal for natural privacy screens, wide hedges, living fences, or specimen trees.
Types of Arborvitae Trees
The five species of arborvitae trees (Thuja) are:
- American arborvitae or Eastern arborvitae (Thuja occidentalis)
- Giant arborvitae (Thuja plicata)
- Korean arborvitae (Thuja koraiensis)
- Japanese arborvitae (Thuja standishii)
- Sichuan Arborvitae (Thuja sutchuenensis)
Two species – American arborvitae and Giant arborvitae are native to North America, where they are popular garden landscaping plants. Their dense green foliage and fast growth make arborvitaes versatile plants that grow under various conditions.
The two main types of arborvitae that are common in North America are:
- American arborvitae (Thuja occidentalis). The American or eastern arborvitae is a popular garden landscape plant. In residential gardens, eastern arborvitaes thrive in well-draining soil and full sun. American arborvitae are cold-hardy plants that have green, greenish-yellow, or bronze foliage. American arborvitae can grow to a height of 49 ft. (15 m) tall, however small cultivars have developed to suit smaller spaces.
- Giant arborvitae (Thuja plicata). The giant arborvitae, or western red cedar, is a colossal conifer tree. Some dwarf western arborvitae species are perfect for front or backyards. The giant arborvitae has a conical shape with lush, evergreen foliage.
Sometimes trees from the genera Platycladus orientalis or Thuja orientalis are called Oriental arborvitae. The Oriental arborvitae is a slow-growing tree that can reach a height of 49–66 ft. (15–20 m) and has light green foliage. This evergreen conifer is ideal for formal or informal hedges and doesn’t lose its color throughout the year. Several small cultivars have been developed such as ‘Aura Nana’.
This article is a complete guide to the most popular types of arborvitaes. Descriptions of Thuja trees and pictures will help you choose the best arborvitaes for your garden landscape.
Types of Arborvitae (With Pictures) – Identification Guide
Most varieties of arborvitae are cultivars of the species Thuja occidentalis (American arborvitae). Most American arborvitaes grow in full sun and moist, well-draining soil.
Depending on the arborvitae species, the dense evergreen foliage grows as cone shapes, upright columns, or rounded shrubs. Small arborvitaes are ideal for foundation plantings, borders, hedges, and privacy screens.
Some arborvitae trees (Thuja) are also named cedar trees, however they are not true cedars as they are in the category of false cedar trees.
Here are descriptions and pictures of the most common arborvitae shrubs and trees.
