Thank You For Celebrating Our 90th Birthday!

Read our full 2024 party report—with lots of great pics!

A total of 325 guests joined us on February 13, 2023 to celebrate 90 years of the Arboretum at our BIRTHDAY BOTANICAL BASH! This year’s Opening Night Party at the Northwest Flower & Garden Festival raised more than $425,000 for our core horticulture, education, and volunteer programs.

A huge THANKS to these dedicated supporters for showering us with birthday love! Thanks also to our generous sponsors, auction donors, event volunteers, and performers! Because of you all, we and our UW and City of Seattle partners can continue to care for the beautiful grounds and plant collections of the Arboretum (with the help of a brand new spider lift!), as well as connect children to the magic of nature, and provide meaningful opportunities for volunteering, recreation, and community building in a safe, uniquely beautiful setting.

Thanks to your generosity, we will continue to enrich our STRONG ROOTS and BRIGHT FUTURE as we countdown to the Arboretum’s centennial in 2034!
