Washington Park International Rose Test Garden Centennial

The International Rose Test Garden (IRTG) in Washington Park is celebrating its centennial this year. It was 1917 when Portland was selected as the location for the national test garden, in part to help preserve European roses threatened by World War I. Today, the Washington Park IRTG is the oldest continuously operating public rose test garden in the United States and welcomes nearly 700,000 visitors each year.
