Portland's International Rose Test Garden is considered the oldest official, continuously-operated, public rose test garden in the United States. Each year hundreds of thousands of visitors from around the world enjoy the sights and scents of the gardens. One of the most popular of Portland’s Parks & Recreation locations, the garden’s spectacular views and more than 8,000 roses make it one of Portland’s most notable signature landmarks. Although twenty-four gardens across the nation now test roses, Portland is the only international rose test garden still receiving roses from around the world to be tested in this mild climate between the Pacific Ocean and the Cascade Mountain range - and is the only North American city that can issue its awards to roses of merit throughout the world.
