Administration Building

Built in the early 1960s, the Administration Building is a melding of post war modernism with Asian influences, notably the 150,000-gallon water garden surrounding it. Beside the Administration Building is the Introduction Garden, which showcases some of the many plant introductions developed by Arboretum scientists and plant breeders. The Arboretum’s four rain gardens are also close by, scattered throughout the nearby parking lot. These rain gardens filter runoff from paved surfaces, cleaning rainwater before it enters the watershed and helping to reduce flooding. Start your exploration of these gardens just outside the Administration Building’s main entrance.

TIPS FOR VISITORS

Stop by the Administration Building lobby to pick up an Arboretum visitor guide and learn about current and upcoming events. Accessible men’s, women’s, and family restrooms are available in the Administration Building, as are vending machines and a water fountain. Parking is available in the adjacent R Street lot, including accessible spots (two of them van-accessible) in front of the building entrance.

Please be aware that the Administration Building closes at 4:30pm daily, half an hour before the Arboretum grounds. After 4:30pm, use the accessible facilities at Arbor House, which is located nearby, next to the R Street entrance gate.
