Set on a hillside in Washington Park, the International Rose Test Garden has more than 10,000 rose bushes and views across Portland toward Mount Hood on clear days. It opened in 1917 to help protect European roses during the First World War, and still tests new varieties. Walk the terraced beds to compare colors and scents, then pause by the fountain or on the lawn. The garden is free to enter. Roses usually flower from April through October, with June often the strongest month for blooms.
A garden created to protect roses
The International Rose Test Garden opened in 1917, when concern about the effects of the First World War on European rose varieties prompted efforts to preserve them. Roses were sent to Portland, where they could be grown and assessed. The garden is now both a public place to walk among the flowers and a testing ground for new rose varieties.
Its work involves assessing qualities such as color, fragrance and resistance to disease. Some varieties are tried here before they reach the commercial market. The collection has more than 10,000 bushes and hundreds of varieties, though counts differ across descriptions of the garden.
Following the terraces
The garden covers about 4.5 acres in Washington Park, west of downtown Portland. Its hillside setting shapes the walk: paths run between terraced beds, with some sloping sections that take more effort than others. You can make a brief loop or spend longer comparing the flowers and stopping to take photographs.
Look for the fountain and statue among the grounds. The Shakespeare Garden is nearby, with plants connected to Shakespeare’s works and roses named for characters in his plays. The open lawn and picnic areas give you a place to rest between the beds. The garden is next to the Portland Japanese Garden, so the two can be visited on the same outing.
When the roses bloom
Roses flower from spring through fall, but the display is usually at its fullest in June. Timing varies across the season: an early visit may find flowers still developing, while some blooms can be fading later on. Outside the main flowering period, the paths and views still make a walk possible, though the roses will be less prominent.
The garden’s elevated position looks out toward downtown Portland and, when the sky is clear, Mount Hood. Early morning or later in the day can be a quieter time to walk and may help with parking. The garden is free to enter, and free tours are available; ask at the gift shop about joining one. Wear comfortable shoes for the hillside paths.
