City of Portland
The Portland Rose Society, established in 1889, is a nonprofit organization dedicated to promoting rose culture and education while encouraging the use of roses in landscaping. The society plays a vital role in the International Rose Test Garden, which serves as a testing ground for new rose varieties, showcasing over 610 different types of roses from late May through October.
The International Rose Test Garden, located in Washington Park, features more than 10,000 individual rose bushes and is recognized for its rigorous testing process, evaluating attributes such as disease resistance and bloom quality. This historic garden not only highlights Portland's long-standing affection for roses but also contributes to the development of new and commercially available rose varieties.
