Originally established by Park Board in 1922,  the Woodland Park Rose Garden is adjacent to the Woodland Park Zoo. The Rose Garden is one of only two dozen certified American Rose Test Gardens in the United States. At its picturesque best from May through August, the garden displays new rose hybrids before they become available to amateur rose enthusiasts. The garden is maintained by the Woodland Park Zoo society. Learn more about the rose garden on the Woodland Park Zoo's Rose Garden web site.
