Administration Building

Built in the early 1960s, the Administration Building is a melding of post war modernism with Asian influences, notably the koi pool that surrounds it. The 150,000-gallon water garden features aquatic plants and brightly-colored Japanese koi, a beloved fixture at the Arboretum. The fish have recently returned to public view after multiple years off display during pool renovations.

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

The Introduction Garden is near the Arbor House, the National Herb Garden, and the National Bonsai & Penjing Museum. All of these areas are handicapped-accessible. The North Court and the East Terrace often both have tables where visitors may stop for a rest or take a bite to eat. There are no regular food services, so please bring your own food. Parking is available in the R Street lot.
