A 2007 photo of the Wish Tree by Jazmine Johnson (The Hirshhorn)

You might wish for world peace, a reunion with a departed loved one, a personal windfall or maybe a ticket to Hamilton. Next week, you’ll be able to make that desire known on Yoko Ono’s Wish Tree for Washington at the Hirshhorn.

The tree has stood in the Hirshhorn’s sculpture garden since 2007, and visitors are invited to whisper their wishes to the tree all year round. But for a brief period every summer, supplies are provided for people to leave written wishes and hang them from the tree’s branches.

Over a career that has spanned more than fifty years, the musician/conceptual artist has developed many interactive works, not all of them so peaceful. For her 1965 performance “Cut Piece,” she invited members of the audience to approach her and cut a piece of the clothing she wore. Now 83, Ono seeks a more gentle form of audience participation.

Ono will not read the wishes, which will be “harvested” by Hirshhorn staff and sent to Reykjavik, Iceland, where they will become part of Ono’s Imagine Peace tower.

Wish Tree for Washington runs from July 1 to Labor Day at the Hirshhorn Museum and Sculpture Garden. On Friday, July 1 at 12:30 p.m., Hirshhorn chief curator Stéphane Aquin will give a gallery talk this and Ono’s related projects.
