Olbrich Botanical Gardens is a 16-acre outdoor botanical garden and 10,000-square-foot conservatory in Madison, Wisconsin.[1] Founded in 1952 and named for its founder, Michael Olbrich, the gardens are owned and operated jointly by the City of Madison Parks and the non-profit Olbrich Botanical Society.
Noteworthy additions to the gardens were the Bolz Conservatory in 1991, and a Thai sala, a gift to the University of Wisconsin–Madison from the Thai Chapter of the Wisconsin Alumni Association and the government of Thailand through its king, Bhumibol Adulyadej.[2] Opened in 2002, it is one of only six sala outside of Thailand and one of two in the United States (the other is located in Hawaii).[3]
