Arboretum@90 Celebrations

Various Dates Throughout 2024

Ninety years ago this year, Washington Park Arboretum was founded by a group of forward-thinking civic leaders who envisioned a glorious natural space in the heart of Seattle.

This year we are celebrating the Arboretum’s 90th year with a series of festive events, including free music concerts and a pup parade.
