The Portland Rose Garden, a beloved icon of the city, has undergone a name change and transformation in recent years. Now known as the Portland International Rose Test Garden, this historic public garden continues to captivate visitors with its stunning displays of roses and panoramic views of the city.
Established in 1917, the Portland Rose Garden was initially created to preserve and promote the city’s rose industry. Today, it stands as a testament to Portland’s commitment to its nickname, the “City of Roses,” and serves as a major tourist attraction.

The Renaming and Expansion
The renaming of the Portland Rose Garden to the Portland International Rose Test Garden occurred in 2019. This change reflected the garden’s growing international significance and its role as a testing ground for new rose varieties.
Concurrently, the garden underwent a significant expansion, adding new rose beds, walkways, and seating areas. These improvements not only enhanced the visitor experience but also allowed for the testing of a greater variety of roses.
International Rose Trials
As the name suggests, the Portland International Rose Test Garden is home to the All-American Rose Selection (AARS) trials. This rigorous testing process evaluates new rose varieties for their hardiness, disease resistance, and overall performance in various climates.
Roses from around the world are submitted to these trials, making Portland a global hub for rose breeding and innovation. The garden’s mild, marine climate provides an ideal environment for testing roses that could potentially be grown in diverse regions worldwide.

Rose Varieties and Gardens
The Portland International Rose Test Garden is home to over 10,000 rose bushes representing more than 650 varieties. These roses are organized into distinct gardens, including the Royal Rosarian Garden, the Miniature Rose Garden, and the Shakespeare Garden, which features roses mentioned in the Bard’s plays.
Visitors can also enjoy the Gold Medal Garden, which showcases roses that have received the AARS gold medal, and the Centennial Garden, which celebrates Portland’s rose heritage with historic and century-old rose varieties.
Visiting the Portland International Rose Test Garden
The Portland International Rose Test Garden is open year-round, with peak bloom typically occurring in late May to early June. Admission is free, making it an accessible and popular destination for both locals and tourists.

To fully appreciate the garden’s beauty, visitors can take a self-guided tour using the garden’s map or join a guided tour led by a Rose City Rose Society volunteer. The garden also hosts special events throughout the year, such as the annual Rose Festival in June.
In its new incarnation as the Portland International Rose Test Garden, this iconic Portland attraction continues to flourish, serving as a global hub for rose breeding and a beloved destination for rose enthusiasts and casual visitors alike.
