What it is

The Bonsai Society of Portland (BSOP) is a member-run bonsai club for the Portland, Oregon area. Its site describes it as “an educational non-profit dedicated to the fine art of bonsai,” and its About page says it has shared bonsai with the Portland community since 1965. It holds monthly general meetings, drop-in Open Studio sessions, workshops, exhibits and an annual holiday party with a live auction. It is a club, not a nursery.

Notes

Finn flags: the About page says “since 1965”; some outside directories give a 1966 founding year, so the listing uses the club’s own wording. The home page lists the November 7 Open Studio in the Camas Room, while the Events page says the Grape Room; both are at the Milwaukie Community Center. The November 16 meeting is posted as 6:00–9:00 PM, which matches the 6:00 PM marketplace and 7:00 PM program.
Related listings: Pacific Bonsai Museum (Federal Way, WA) is already on Bonsai Plaza and is linked from the club’s home page. Bonsai Akira and Mirai (Oregon nurseries) are also already listed; they are separate businesses.
