National Bonsai & Penjing Museum Renovations
Soon, the National Bonsai & Penjing Museum will be an even more beautiful home for the nation’s premiere public bonsai and penjing collections!
Starting in mid-August and continuing into early October, the museum will be undergoing minor renovations. Although areas of the museum will be closed to the public, all of the trees will remain on display throughout the renovation period. Please follow all posted signage when visiting the museum.
This work is made possible by the National Arboretum’s primary nonprofit partner, the Friends of the National Arboretum.
