Pacific Bonsai Museum opens tickets for Branch Out 2025 fundraiser

Pacific Bonsai Museum opened tickets for Branch Out 2025, its annual fundraiser and biggest event of the year, set for Sunday, September 28, from 1 to 4 p.m. at the former Weyerhaeuser headquarters building in Federal Way. Tickets started at $150, and the museum later posted that Branch Out had sold out, a clear sign that seats for this kind of access did not stay available for long.

The strongest draw was the venue itself. Pacific Bonsai Museum used its public news page and social posts to highlight that Branch Out would take place inside the former Weyerhaeuser headquarters, a building the museum described as an architectural icon that is rarely open to the public. In one reel, the museum pointed to the building directly and told followers that September 28 was the chance to step inside for the fundraiser.

That setting gives Branch Out a different weight from a routine evening program or ticketed exhibition opening. The former Weyerhaeuser headquarters sits on the Weyerhaeuser corporate campus in Federal Way, and its scale and history help frame the museum’s major fundraiser as an event with more than one layer of appeal. For bonsai collectors, club members, and local supporters, the value was not only in backing the museum but in getting inside a landmark space tied to the region’s corporate and architectural history.

The building itself adds another reason the event mattered. Seattle Refined noted that the Weyerhaeuser corporate headquarters was built in 1971, and that the property was sold to a Los Angeles developer in 2016. That timeline makes Branch Out feel like a rare opening of a private landmark as much as a museum fundraiser, which helps explain why the museum emphasized the venue so heavily across its posts.

By the time Pacific Bonsai Museum confirmed that Branch Out 2025 was sold out, the message was already clear: early reservations mattered. The combination of limited public access, a one-day-only fundraising window, and a $150 starting price turned this into the museum’s marquee date, with the former Weyerhaeuser headquarters providing the kind of setting bonsai fans would not want to leave to chance.
