International Rose Test Garden is Portland’s free public rose garden at 400 SW Kingston Avenue, in Washington Park in the Arlington Heights neighborhood. Founded in 1917, it grew from rose enthusiast Jesse A. Currey’s proposal to safeguard European roses threatened by World War I. Today, more than 10,000 rose bushes fill terraced beds above downtown, drawing visitors for fragrance, horticultural variety, and views toward Mount Hood on clear days.
What to Expect at International Rose Test Garden
The approximately 4.5-acre garden combines formal rose beds, lawn, mature trees, and paved promenades across several hillside terraces. More than 600 varieties illustrate the differences between hybrid teas, floribundas, climbers, and miniature roses. Labels make this an unusually useful stop for gardeners: compare flower forms, colors, and plant habits rather than treating every bed as another photograph. Roses generally flower from late May into October, with June usually delivering the strongest first flush; weather shifts the exact timing.
Start with the main beds, then explore the named specialty gardens. The Gold Medal Garden showcases award-winning roses, while the Royal Rosarian Garden connects the collection with Portland’s ceremonial rose ambassadors. The Shakespeare Garden broadens the planting beyond roses with plants associated with the playwright’s works. Stonework, clipped borders, and the outdoor amphitheater give the grounds structure even outside flowering season. This remains a working test garden, where new roses are evaluated for qualities such as flowering performance, disease resistance, and fragrance.
- Main rose terraces: Thousands of labeled plants offer close comparisons of color, scent, and growth habit.
- Gold Medal Garden: Award-winning selections provide a concentrated introduction to celebrated rose cultivars.
- Royal Rosarian Garden: Dedicated plantings honor members of Portland’s longstanding civic rose organization.
- Shakespeare Garden: Literary associations and mixed planting create a quieter contrast to the principal rose beds.
- City and mountain outlook: Open viewpoints frame downtown Portland and, when visibility allows, Mount Hood.

Visiting Tips, Getting There & Nearby Pairings
Arrive on a weekday morning for easier parking and space around the busiest beds. Early light suits flower photography; allow extra time after rain to avoid wet benches and slippery surfaces. No admission reservation is needed. Paid parking near the garden also serves neighboring attractions and fills quickly on summer weekends. For a car-free visit, take the MAX Blue or Red line to Washington Park station and connect with the free park shuttle when operating; check TriMet schedules before departure. The station is not beside the roses, and walking from it involves a substantial hilly park route.
Accessibility improvements completed in 2017 created an accessible connection between the parking area and the main garden promenade. Paved routes, ramps, benches, and accessible restrooms support wheelchair and stroller visits, although this is a terraced hillside with sloping approaches and stairs on some shortcuts. Use the main accessible route rather than following every stepped connection. Pair the roses with the Portland Japanese Garden entrance, roughly five minutes uphill, or Washington Park’s playground and the Lewis and Clark Memorial, approximately five to fifteen minutes away. Keep dogs leashed, leave flowers unpicked, and favor daylight: the late closing time does not mean every garden path is brightly lit.
