What Kind of Trees are Planted at Ground Zero

The 9/11 Memorial in Lower Manhattan is a place of solemn remembrance and reflection for the thousands of lives lost in the terrorist attacks of September 11, 2001. In addition to the reflective pools and granite inscriptions, the site features a lush grove of trees that symbolize hope, renewal, and resilience in the face of tragedy. So, what kind of trees are planted at Ground Zero?

Swamp White Oak

The main species of tree at the 9/11 Memorial is the Swamp White Oak (Quercus bicolor). These trees are native to the United States and are known for their hardiness and adaptability to different soil types. They can grow up to 60 feet tall, with a trunk diameter of up to 3 feet. The Swamp White Oak is a deciduous tree that blooms in the spring, producing a profusion of pale green flowers.

The trees at the 9/11 Memorial were carefully selected for their ability to thrive in urban environments, such as the highly-trafficked location of the Memorial. According to the designers of the Memorial, the Swamp White Oak was chosen for its “resilience, longevity, and grace”.

Other Species of Trees at the 9/11 Memorial

In addition to the Swamp White Oak, the Memorial also features several other species of trees that provide variety and diversity to the landscape. These include:

Little Leaf Linden (Tilia cordata) – a deciduous tree known for its heart-shaped leaves and fragrant yellow flowers

American Elm (Ulmus americana) – a tall, graceful tree with a vase-like shape and serrated leaves

Sassafras (Sassafras albidum) – a small tree with distinctive three-lobed leaves and aromatic bark and roots

Sweetgum (Liquidambar styraciflua) – a hardwood tree that produces spiky fruit balls and vibrant fall foliage

Caring for the Trees at the 9/11 Memorial

The trees at the 9/11 Memorial are more than just decoration – they serve an important ecological function in the urban environment. Along with providing shade and a beautiful landscape, the trees help absorb carbon dioxide and other pollutants from the air, reduce soil erosion, and support biodiversity by providing habitats for birds and insects.

To make sure these trees stay healthy and continue to thrive, the Memorial staff works closely with horticultural experts to provide proper care and maintenance. This includes regular pruning and soil testing, as well as monitoring for pests and diseases.

The Symbolic Importance of the Trees

The trees at the 9/11 Memorial are not just a beautiful addition to the landscape – they have important symbolic meaning as well. According to the designers of the Memorial, the trees represent “life, rebirth, and renewal” – a powerful message in the aftermath of such a tragic event.

The design of the Memorial includes a “Survivor Tree”, a Callery Pear tree that was recovered from the rubble of the original World Trade Center site and nursed back to health. The tree now stands as a symbol of resilience and hope, and serves as a reminder of the strength of the human spirit.

Conclusion

The trees at the 9/11 Memorial are a beautiful and meaningful addition to the site, providing a place for reflection and a symbol of hope and renewal. From the hardy Swamp White Oak to the delicate Little Leaf Linden, each tree adds its own character and ecological benefits to the landscape. The care and attention given to these trees ensures that they will continue to thrive and serve as a lasting legacy for generations to come.
