Unique Elements of Olmsted's Design

The Summerhouse on the U.S. Capitol Grounds

Tucked away on Capitol Hill is a small brick structure designed by Frederick Law Olmsted called the Summerhouse. Since 1881, the Summerhouse has offered a cool, relaxing space for visitors who have come to explore the Capitol, especially on hot and humid days.

Join one of our Education Specialists to learn more about the preservation of the Summerhouse from Director of Capitol Grounds and Arboretum Jim Kaufmann and Mason Assistant Supervisor Michael Jarboe.

Cherry Blossoms on the U.S. Capitol Grounds

Did you know that the U.S. Capitol is an arboretum? With over 5,000 species of plants, including many flowering cherry blossom trees, the Capitol Grounds burst with vibrant colors year-round.

We spoke to Emily Mueller, Plant Specialist and Entomologist, to get the buzz on how the Capitol’s Grounds staff and the local pollinators work together to keep each flower, root, and branch thriving.

Preserving Historic Cherry Blossoms on the U.S. Capitol Grounds

Learn about the cherry blossom trees that were gifted by Japan with Fran de la Mota, Deputy Director of the United States Capitol Grounds and Arboretum. He highlights where you can find some of the original trees, and discusses a traditional Japanese method being used to preserve the aging cherry trees on the Capitol campus.

Hardscapes on the U.S. Capitol Grounds

In 1873, Frederick Law Olmsted looked at the 58 acres that make up the U.S. Capitol Grounds and saw not only the need for trees and flowers, but also hardscapes. Olmsted included walking paths, light fixtures, fountains, and stone walls that make navigating the natural features more inviting for visitors.

Preservation Architect Marty Shore and Mason Assistant Supervisor Michael Jarboe explain how we continue to preserve Olmsted’s hardscapes and the timeless beauty of the grounds.

Trees on the U.S. Capitol Grounds

Some of the oldest trees that continue to stand on the U.S. Capitol Grounds date to the 1870s! Frederick Law Olmsted planted trees with the intent that each one would complement the view of the Capitol’s iconic dome.

Arborist Matt Rawson and Urban Forester Melissa Westbrook joined us to share how we honor Olmsted’s original designs, expand on his vision, and maintain the health of these living artifacts of the past.
