History of The Botanical Gardens 

The Tucson Botanical Gardens was founded in 1964 by Harrison G. Yocum. Harrison was known to be a Horticulturist which is defined as an expert in cultivation and management. The Tucson Botanical Gardens grew out of Yocum's personal garden, which had a diverse variety of cactus and palms. Yocum was a horticulturist and collector who opened his home garden to the public and eventually created a membership club for his large garden collection. Due to his extensive collection of cacti and palms, the organization only increased by members. The membership program became available in 1968 and the following year, the program became a non for profit cooperation. It was not until the membership reached 100 charter members that the decision to temporarily place the garden in a green house at Rudolph Park was put into play until they found a permanent place to put the garden. A fundraiser was formulated by friends and local garden clubs to fulfill the dream of a larger and perminant home for the garden. Eventually, in 1974 the Tucson Botanical Gardens found a perminant home at the historic porter family property. The mission of the Tucson Botanical gardens is to connect people with plants and nature. This is done through the extensive amount of art, science, history, and culture shared. 

Rutger Bleeker Porter and Bernice Porter

The Porter family also took much interest in gardening. The couple started Desert Gardens Nursery at their home in 1931. Rutger Porter had been an avid landscaper known for his work at the Desert Sanatorium (Tucson Medical Center) and for creating the Desert Garden Nursery also known as Porterville. The Porter estate began with numerous landscaped patios and gardens including a mixture of natives and mediterranean plants. The original garden included winding walks, low adobe walls, foundations, along with beautiful greenery around the home. Unfortunantly, In 1958 The Desert Gardens Nursery closed and Rutger Porter passed away six years later. As a result of this, Bernice Porter donated the garden to the City of Tucson making it a city garden. When the Tucson Botanical Gardens heard of the Porter family’s goals for their garden they petitioned the city for the land. During this time the Porter family and the Tucson Botanical Gardens non-profit grew close because of their common goals.

A quote from tucsonbotanical.org by Bernice Porter: "Today a botanical garden must be much more than pleasurable, interesting, exotic. Now the necessity is a fuller understanding and application of the relationship of plants with all other life on the planet. We must realize, as never before, that plants, which are support by the earth, support the earth.”

Tucson Botanical Gardens Expansion

The union between the Tucson Botanical Gardens and the Porter property became a reality by the early 1970s. In 1974, the Tucson City Council officially passed Resolution 9384 which stated that “the property would be used for the development of a botanical garden to serve as a horticultural center, a sanctuary for wild birds, and as a center for education.” The president of the Tucson Botanical Garden’s non-profit at the time, Boyd Allen, was then responsible for converting the Porter Desert Garden Nursery into the ideal location for the Tucson Botanical Gardens. After the resolution passed Mrs. Porter said, “We just didn’t want to see this place go down under a bulldozer… Now it will continue to offer as much pleasure to others as we have enjoyed in the past." . Preserving the historical aspects of the property, many of the buildings located on the site date back to the 1920s and were constructed of adobe brick. Bernice was also allowed to live on the property until her death in 1983 and was often cited as helping the Tucson Botanical Garden become accustomed to their new home on Grant and Maple.
