In the vast and rugged landscapes of Wyoming, a majestic tree species stands tall, symbolizing the resilience and beauty of this western U.S. state. Meet the Wyoming State Tree: Platycladus orientalis, commonly known as the Eastern Arborvitae or the Oriental Arborvitae. This evergreen conifer holds a special place in the natural heritage of Wyoming, serving as a symbol of strength, longevity, and the enduring spirit of the state.
The Selection of Wyoming’s State Tree
The journey to selecting a state tree for Wyoming began with a desire to honor and represent the unique natural environment of the state. The process involved careful consideration of various tree species that thrive in Wyoming’s diverse ecosystems, from the high plains to the Rocky Mountains.
The Eastern Arborvitae was chosen for its distinctive characteristics and its ability to withstand the harsh winters and arid conditions that define much of Wyoming's climate. With its dense, upright growth habit and its ability to adapt to a range of soil types, the Arborvitae exemplifies the resilience and adaptability that Wyomingites are known for.
The tree's scientific name, Platycladus orientalis, is derived from Greek and Latin roots, meaning "flat branches growing eastward." This description perfectly encapsulates the tree's distinctive flat branchlets and its historical distribution in Asia, particularly in China and Korea.
A Symbol of Wyoming’s Natural Beauty
The Eastern Arborvitae holds deep symbolic value for the people of Wyoming. Its evergreen nature, remaining verdant throughout the year, represents the enduring spirit and vitality of the state. Despite the challenges of winter and the dry summers, the Arborvitae stands tall and green, much like the unwavering determination of Wyoming’s residents.
The tree's fragrant, scale-like foliage adds to its appeal. The aroma of the Arborvitae has been likened to a fresh, piney scent, evoking a sense of peace and tranquility. This aroma is not just pleasant; it also serves a practical purpose, as the essential oils produced by the tree's leaves have insect-repelling properties, a useful adaptation in Wyoming's wilderness.
Furthermore, the Arborvitae's longevity contributes to its significance. Some Arborvitae trees can live for hundreds of years, with their sturdy, enduring presence becoming a living testament to the passage of time. This longevity mirrors Wyoming's rich history and its enduring connection to the land.
Cultural and Historical Significance
The Eastern Arborvitae has played a role in the cultural and historical tapestry of Wyoming and beyond. Native American tribes, such as the Lakota and Cheyenne, have utilized various parts of the tree for medicinal purposes and in their traditional crafts. The tree’s wood, known for its durability and resistance to decay, has been used for making utensils, tools, and even canoes.
In modern times, the Arborvitae continues to be a beloved and functional part of Wyoming's landscape. Its dense growth habit makes it an excellent choice for windbreaks and privacy screens, while its aesthetic appeal and low maintenance requirements make it a popular choice for landscaping in residential and commercial areas.
Eastern Arborvitae: A Botanical Profile
The Platycladus orientalis, or Eastern Arborvitae, is a species of coniferous tree belonging to the Cupressaceae family. It is native to eastern Asia but has been successfully introduced and cultivated in various parts of the world, including North America.
Here are some key botanical characteristics of the Eastern Arborvitae:
- Growth Habit: The Arborvitae typically grows in a pyramidal or columnar shape, with dense, flat branches that extend horizontally. It can reach heights of up to 50 feet (15 meters) with a spread of 10-20 feet (3-6 meters) at maturity.
- Foliage: Its foliage is composed of small, scale-like leaves that are dark green in color. These leaves are arranged in opposite pairs, creating a flattened appearance on the branchlets.
- Cones: Arborvitae trees produce small, rounded cones that are about 0.5 inches (1.3 cm) in diameter. These cones are initially green but turn brown as they mature. They contain small, winged seeds that are dispersed by the wind.
- Bark: The bark of the Arborvitae is thin, smooth, and grayish-brown in color. It may develop shallow furrows and scaly ridges as the tree ages.
- Adaptability: One of the Arborvitae's standout features is its adaptability to a range of growing conditions. It can tolerate a variety of soil types, including clay, loam, and sandy soils, and is able to withstand drought once established.

Growing and Caring for Arborvitae
If you’re considering adding an Eastern Arborvitae to your landscape, here are some tips for successful cultivation:
- Planting Location: Choose a sunny to partially shaded spot with well-drained soil. Avoid low-lying areas where water may collect, as Arborvitae prefers drier conditions.
- Soil Preparation: Ensure the soil is rich in organic matter and slightly acidic to neutral in pH. You can improve soil quality by adding compost or other organic amendments.
- Watering: Newly planted Arborvitae requires regular watering to establish a strong root system. Once established, it becomes more drought-tolerant but will benefit from occasional deep watering during dry periods.
- Pruning: While Arborvitae does not require extensive pruning, you may want to trim it to maintain its shape or remove any dead or diseased branches. The best time to prune is in late winter or early spring before new growth begins.
Eastern Arborvitae’s Role in Ecosystem
The Eastern Arborvitae plays a vital role in Wyoming’s ecosystem. Its dense foliage provides habitat and shelter for a variety of wildlife, including birds, small mammals, and insects. The cones and seeds serve as a food source for birds, particularly during the winter months when other food sources may be scarce.
Additionally, the Arborvitae's ability to tolerate harsh conditions makes it an important species for stabilizing soils and preventing erosion. Its deep root system helps to hold the soil in place, especially in areas prone to wind and water erosion.
Environmental Benefits
The environmental benefits of the Eastern Arborvitae extend beyond its local ecosystem. As an evergreen tree, it plays a role in sequestering carbon dioxide and releasing oxygen, contributing to improved air quality. Its dense growth habit also provides natural windbreaks, helping to reduce wind speed and protect nearby plants and structures.
Furthermore, Arborvitae trees have been found to have a positive impact on water conservation. Their deep roots can access groundwater, reducing the need for frequent irrigation. This makes them an excellent choice for xeriscaping and sustainable landscaping practices.
The Future of Wyoming’s State Tree
As Wyoming continues to face environmental challenges, such as climate change and land development, the role of the Eastern Arborvitae as a symbol of resilience and sustainability becomes increasingly important. Its ability to adapt and thrive in challenging conditions makes it an ideal representation of Wyoming’s spirit and natural heritage.
Efforts are being made to preserve and promote the growth of Arborvitae populations in Wyoming. Conservation initiatives focus on protecting native habitats, educating the public about the tree's significance, and encouraging its use in landscaping and restoration projects.
In conclusion, the Platycladus orientalis, or Eastern Arborvitae, stands tall as a symbol of Wyoming's natural beauty, resilience, and enduring spirit. Its selection as the state tree is a testament to its adaptability, ecological importance, and cultural significance. As Wyoming looks to the future, the Arborvitae will continue to inspire and remind us of the strength and vitality that resides in the heart of the state's natural landscape.
