Museum tours and family activities mark the anniversary in Washington, with a separately listed evening Science Café devoted to bonsai.

All times are local to the venue · America/New York
The National Bonsai & Penjing Museum’s 50th anniversary offers a reason to explore a collection whose trees can be much older than the institution itself. The celebration at the U.S. National Arboretum on Saturday, November 7, 2026, includes museum tours and family activities.
The Arboretum describes the museum as home to hundreds of bonsai trees, including specimens that are centuries old. The anniversary brings attention to that living collection through tours, although the announcement does not give tour times or routes.
Family activities are also on the daytime program. Their formats and suggested ages are not specified, so families hoping to plan around a particular activity should check with the organizer before setting out.
The museum normally keeps the same 10 a.m. to 4 p.m. hours as the celebration. The Arboretum also reports minor museum renovations from mid-August into the fall: some areas will be closed during the work, but all trees are to remain on display. No completion date is given, so it is worth checking conditions for November 7 and following any posted signs.

The museum sits within a 451-acre public garden and research facility in Northeast Washington, along the Anacostia River. Established in 1927 and administered by the U.S. Department of Agriculture’s Agricultural Research Service, the Arboretum combines public collections with horticultural research. Its work has produced plant introductions resistant to pests and disease for the nursery industry.
For a wider visit, the National Herb Garden offers a different way to look at a plant collection: it has a knot garden, a rose garden and 10 beds arranged by theme. The Washington Youth Garden grows food crops and teaches garden-based science to children and families.
Another choice is the Capitol Columns, once part of the U.S. Capitol’s East Portico and now set above a meadow at the Arboretum. The Arboretum’s official app includes a grounds map, collection information and self-guided tours, which can help visitors choose where to go beyond the museum.

The anniversary announcement mentions a science café, and a separate Science Café listing describes an evening session about the science of bonsai. The pages do not establish whether those references describe the same program or whether the evening session requires registration.
The distinction matters because the separately listed café falls after the Arboretum’s normal 5 p.m. grounds closing. Ask the organizer about evening entry and any booking arrangements rather than assuming the regular entrance schedule applies.
