Are There Different Types of Arborvitae?

When you picture a classic evergreen hedge, the chances are good that you are looking at some form of arborvitae, a name that often sparks the question, are there different types of arborvitae. These evergreen trees and shrubs are beloved for their dense, conical growth, year round color, and versatility in the landscape, yet the world of ar Arborvitae is far more diverse than the familiar green hedge you see on the side of the road. Understanding the variety available allows you to choose the perfect plant for privacy, structure, or pure ornamental effect.

Many gardeners assume there is just one species, but the truth is that nurseries and botanical gardens cultivate numerous species and hundreds of cultivars, each offering subtle differences in color, texture, and habit. From the fast growing American types to the slow sculpting Gold varieties, the answer to are there different types of arborvitae is a resounding yes. Exploring these options reveals a spectrum of plants that can fit into almost any garden design, whether you need a towering screen or a low maintenance groundcover.

American And Western Arborvitae Varieties

The large, stately trees often used for grand landscapes belong primarily to the American and Western species groups. These are the giants of the arborvitae world, chosen for their impressive vertical presence and ability to create an instant visual barrier. Selecting between them requires understanding their specific climate preferences and growth habits.

American arborvitae, also known as Eastern white cedar, thrives in cooler northern climates and is famous for its bright green foliage and conical shape. Western red cedar, its counterpart on the west coast, offers a more rugged bark and a slightly more flexible growth pattern. Both species provide excellent screening but can become quite large, so planning space is essential.

Thuja Occidentalis Forms

The classic American types fall under the botanical name Thuja occidentalis, and within this species, you will find a wide array of forms. Some varieties are narrow and columnar, perfect for tight corridors, while others spread wide like a layered pyramid. Their scale like foliage releases a pleasant aroma when crushed, adding a sensory element to the visual appeal.

These forms are generally hardy and reliable, making them a staple for traditional landscapes. However, their mature size can be daunting; a young sapling can transform into a massive tree over a decade, shading out nearby plants. This reality underscores the importance of checking the specific mature dimensions listed on the nursery tag before making a purchase.

Thuja Plicata Forms

On the other side of the continent, Thuja plicata, or Western red cedar, dominates the Pacific Northwest. These trees are significantly larger and more vigorous, often reaching heights that surpass residential structures. They feature a rich, reddish brown bark and softer, more feathery foliage compared to their Eastern relatives.

Because of their size, these varieties are better suited for rural properties or large estates where they can serve as a majestic backdrop. They are less commonly mounded into tight hedges and more often left to grow into towering specimens that define the skyline of a property.

Dwarf And Compact Arborvitae Types

Not every garden has the room for towering trees, and this is where the true diversity of are there different types of arborvitae becomes most apparent. The dwarf and compact categories have exploded in popularity among modern landscapers who want the look of evergreen structure without the maintenance of constant pruning.

These slow growing cultivars are bred to stay small, often maxing out at knee height or waist height. They introduce year round interest to the front of a border, to a rock garden, or to a container on a patio. Their reduced size makes them accessible to homeowners in smaller lots or urban environments.

Golden And Yellow Varieties

One of the most dramatic variations is the shift from deep green to vibrant gold. Thuja occidentalis 'Golden Globe' and similar cultivars bring a warm, sunny feel to the winter landscape. These types maintain their color intensity, especially when grown in full sun, where the golds can shimmer like miniature bursts of light.

Another popular option is Thuja occidentalis 'Smaragd', which offers a richer, lime green hue that is more intense than standard green varieties. These golden types are excellent for adding contrast to a foundation planting, pairing beautifully with dark evergreens or flowering shrubs.

Vermiculite And Unique Foliage Textures

Beyond color, there are variations in texture and even the growing medium. Some dwarf varieties, such as those involving vermiculite in their potting mixes, exhibit a slightly different foliage density or resilience. These subtle differences affect how the plant feels and how it handles environmental stress.

Textural variety is also present in species like Thuja koraiensis and Thuja sutchuenensis, which are less common but highly regarded for their fine, lacy foliage. These Asian varieties introduce an elegant, almost fern like quality to the garden, providing a distinct alternative to the bolder American shapes.

Growth Habits And Landscape Applications

Answering are there different types of arborvitae is also about understanding how these plants behave over time. Some varieties are strictly upright, others spread horizontally, and a fortunate few actually weep or cascade. Matching the habit to the function is the key to a successful design.

For instance, a fastigiate, or columnar, variety is the undisputed champion of small space privacy. Planted in a row, they create a solid green wall that does not widen the footprint. Conversely, a sprawling variety works beautifully on a slope, where its natural tendency to root into the ground helps prevent erosion.

Screening And Windbreak Options

If your goal is to block neighbors or reduce wind, you will likely look at the faster growing varieties. These plants establish quickly and provide a dense barrier that muffles sound and creates a private sanctuary. The density of the foliage is usually high, meaning you cannot see through the hedge, which is the ultimate goal for screening.

However, even within the screening category, there are choices. Some hybrids offer enhanced disease resistance, which is vital in humid climates where bagworms or blight can be problematic. Choosing a resilient type ensures your screen remains intact and attractive year round.

Ornamental And Container Use

Not every arborvitae needs to be planted in the ground. Many of the dwarf and compact types thrive in pots, offering flexibility for renters or anyone who wants to rearrange the garden seasonally. The contrast between a tight ball of green foliage and a rustic ceramic pot is a classic combination that never goes out of style.

Select varieties with naturally slow growth for containers, as they will require less frequent repotting. Pairing them with spring blooming bulbs or summer annuals creates a dynamic display, while the evergreen core ensures the pot looks full even in the dead of winter.

Ultimately, the world of arborvitae offers a solution for almost every landscape challenge, and the journey of exploring these different types is one of the most rewarding aspects of gardening.

Taking the time to match the specific variety to your space, sunlight, and aesthetic goals ensures you will enjoy these versatile plants for decades to come.
