Best International Rose Test Garden Tours from Seattle

The longest-running community test rose garden in the United States is this Portland jewel that tries out new rose varieties. The Portland International Test Rose Garden was established in 1917 at the suggestion of Jesse A. Currey, who feared for the survival of Europe's hybrid roses during World War I. The garden has more than 10,000 rose plants making up about 550 varieties. The site also features the Gold Medal Garden, Miniature Rose Test Garden and the Shakespeare Rose Test Garden.
