The museum holds a Japanese white pine that has been in training since 1625, surviving the atomic bombing of Hiroshima in 1945.
The collection includes trees donated by Masaru Yamaki, who secretly maintained the Hiroshima-surviving pine before gifting it to the U.S.
Bonsai refers to the Japanese art of tray gardening, while Penjing is the older Chinese precursor focused on more naturalistic landscapes.
The museum collection is supported by the National Bonsai Foundation, a private nonprofit partner.
Some specimens are considered 'living sculptures' and have been passed down through generations of families before entering the museum.
The trees are displayed in specialized galleries that mimic climate-controlled environments and traditional aesthetic settings.
The museum maintains an extensive library of literature on the history and horticulture of miniature trees.
The collection includes native North American species styled with techniques originally developed in East Asia.
The museum staff must perform delicate root pruning and wire-shaping on a seasonal cycle to maintain the trees' miniature stature.
The museum landscape design includes stone paths and water features intended to evoke specific Japanese and Chinese garden aesthetics.
The National Bonsai & Penjing Museum is located within the U.S. National Arboretum and houses a living collection of trees from Japan, China, and North America. It features three permanent exhibition galleries—the Japanese, Chinese, and North American collections—plus a rotating special exhibit pavilion. The museum originated in 1976 as a Bicentennial gift from the Nippon Bonsai Association to the United States. Many specimens in the collection are centuries old, including trees that have been trained for over 350 years. The display is curated to show both the aesthetic art of miniature tree styling and the horticultural science required for long-term survival. The layout incorporates traditional landscape design elements to maintain a specific cultural atmosphere for each collection. It functions as a research and educational facility alongside its public exhibition role. The site includes a dedicated study center for the history and techniques of bonsai and penjing.
The central courtyard of the Japanese Collection, which provides a balanced view of the pagoda-style structures and the trees.

Bring a magnifying glass to appreciate the fine detail of the trunk textures and moss work on the older specimens.
Wear comfortable walking shoes as the museum is one of several collections within a very large arboretum site.
Trying to see the entire 446-acre National Arboretum on foot; it is best to focus on the museum area specifically.
Closed on December 25th; museum galleries may close briefly for plant maintenance or rotation.
