International Rose Test Garden
International Rose Test Garden is the oldest official continuously operated public rose test garden in the United States and features more than 10,000 roses. It started as a safe haven for hybrid roses grown in Europe during World War I. Flowers began arriving in Portland in 1918 and the garden and amphitheater were dedicated in 1924. The grounds are split into several smaller areas: the Royal Rosarian Garden, the Shakespeare Garden and the Miniature Rose Garden. The garden is open daily and admission is free. While great city views are offered year-round, the best rose-viewing months are May through September. (When you’re finished admiring the flowers, head just uphill to the majestic Portland Japanese Garden for more fabulous flora.) (Portland, Oregon, USA)
