Portland Botanical Gardens, an Oregon nonprofit public benefit corporation, formed in 2020 with a vision to establish research and education focused botanical gardens in the City of Portland.

After considering more than a dozen potential sites, Portland Botanical Gardens finalized a Purchase and Sale Agreement (PSA) in 2024 to acquire the fifty-nine acre McCormick & Baxter Superfund Site along the Willamette River in North Portland, and intends to close in 2027.
