The International Rose Test Garden is a rose garden in Washington Park in Portland, Oregon, United States. There are over 10,000 rose bushes of approximately 650 varieties. The roses bloom from April through October with the peak coming in June, depending on the weather.[1] New rose cultivars are continually sent to the garden from many parts of the world and are evaluated on several characteristics, including disease resistance, bloom formation, color, and fragrance.[1] It is the oldest continuously operating public rose test garden in the United States and exemplifies Portland's nickname, "City of Roses". The garden draws an estimated 700,000 visitors annually.[2]
