The Northwest Flower & Garden Festival returns to the Convention Center in mid-February, and for the first time since the start of the pandemic, the Arboretum Foundation will again kick off the event with its annual Opening Night Party.

Please join us on February 14 for LOVE IN BLOOM! Enjoy a delicious dinner, fabulous performances, and an exclusive sneak peek at the Festival displays the day before they open to the public. What better way to celebrate Valentine’s Day than with friends, food, flowers, and fun—all to benefit the Washington Park Arboretum!

We are pivoting from a live auction format to fun “sign-up experiences,” such as bird tours, hikes with horticultural experts, visits to fabulous local gardens, and more. Embrace the Arboretum and get your ticket today!

Ticket Price Includes: FREE PARKING at the Convention Center, plus two FREE PASSES to the Garden Festival for use later in the week (Feb 15 to 19).

All proceeds from Opening Night help fund environmental education, maintenance, and volunteerism at Washington Park Arboretum.
