Horticulturist and collector Harrison G. Yocum started the Tucson Botanical Gardens in his home in 1964. After moving to Randolph Park, the gardens moved to their current location, at the historic Porter Family property, in 1974. The five-and-a-half-acre Tucson Botanical Gardens is home to a range of plants native to the local region, including cacti and arid plants. Its Butterfly & Orchid Pavilion, open from October to May, features a display of live tropical butterflies from five continents. The garden also showcases orchids, bromeliads and jungle vegetation.
