What is Oregon Garden?
This 130-acre site holds more than twenty distinct gardens, including rose, children’s, conifer, and sensory areas. A centuries-old Oregon white oak stands among native groves, and winding paths cross water features. The grounds also include the Gordon House, a Frank Lloyd Wright design, and an outdoor amphitheater.
The history of Oregon Garden
The idea began with Oregon nursery growers in the 1940s. In the 1990s, Silverton sought to use its reclaimed wastewater, and the city bought land south of downtown in 1995 for the project. Construction started in 1997, and the garden opened to the public in April 1999.
What there is to see
The garden spans 130 acres of a planned 240-acre site. It relies entirely on filtered municipal wastewater for irrigation, using a system of terraced wetlands and 25 treatment ponds. This setup also supports nearby farmland and fulfills environmental mitigation requirements for a local industrial park.
When to go
Open every day of the year, it welcomes over 100,000 visitors annually. It hosts public events, concerts at the Teufel Amphitheater, and an autumn festival. Each Earth Day since 1999, it offers free admission with environmental exhibits and workshops.
Why Oregon Garden matters
The garden includes the Gordon House, the only Frank Lloyd Wright home in Oregon and the sole one in the Pacific Northwest open to the public. Its water garden received a national award in 2002 for environmental design. A 400-year-old white oak on-site is listed as an Oregon Heritage Tree.
