The Exhibit

In April of every year, in collaboration with the U.S. National Arboretum, I.I. Chapter No.1 puts on an exhibit for the public, and the Chapter’s members prepare magnificent arrangements and free workshops. This year’s Exhibit is special because 2026 marks the 70th Anniversary of I.I. Chapter No. 1, which we will be celebrating at the April Exhibition.

This year’s Exhibit will be open to the public from April 3rd through April 12th. You will find detailed information on this page and also on the USNA website under Calendar of Events.

The arrangements are changed, and new arrangements are installed on April 3, April 6, and April 9. Each of our Chapter’s Ikebana Schools will be represented.

2026 is also the U.S. National Arboretum Bonsai Museum’s 50th Anniversary, and we join our friends at the USNA in their celebration of this milestone.
