The International Rose Test Garden is a 4.5-acre garden between downtown Portland, East Portland, and the Willamette River. On clear days, the garden enjoys views of the Cascade Range and Mount Hood. There are more than 10,000 rose bushes of about 650 varieties. The roses are at full bloom from April to October, but the peak is in June. New rose cultivars are sent to the garden from all over the world, and rose breeders and distributors from all parts of the world usually donate about 2,500 roses every year to the garden. They are evaluated for disease resistance, color, bloom formation and fragrance. The garden is responsible for Portland's nickname, "City of Roses."
