Extended Business Description
The primary purpose of the garden is to serve as a testing ground for new rose varieties. The garden traces its origins to World War I. While the war was raging, hybridists sent roses from around the world to Portland’s garden for testing.
The majority of roses in the garden are commercially available. About 10 to 20 varieties are replaced each year with some of the best new roses released onto the market. Roses bloom from late May to October, depending on the weather. Learn more at https://www.portland.gov/Parks/Washington-Park-International-Rose-Test-Garden
