Did you know that the cactus family is one of the top five most threatened groups of organisms on Earth? The Desert Botanical Garden is committed to help save the cactus and we need your help. Since 1939, the Garden has been working to preserve the desert. In addition, we house and display the world's finest collection of cacti and desert plants. The Garden invites the community to join Cactomania – the public phase of The Saguaro Initiative (TSI) fundraising campaign. 

We're looking for people passionate about our desert landscape to help the Garden conserve and protect it for generations to come. We honor those who make a donation by automatically registering donors as Cactomaniacs. Becoming a Cactomaniac will open the door to be first to receive Garden news and special offers as well as exclusive invitations and fantastic giveaways only available to Cactomanicas.

By joining Cactomania and contributing, you can help protect cacti and help conserve the wonders of the desert for future generations to enjoy. Construction of our new Horticulture Center is just one example of how the TSI campaign advances desert plant conservation. The Center provides space for propagating plants to support conservation and research goals; the facility also includes a learning lab for classes, workshops and citizen science trainings in support of the Garden’s work with other community partners to study, restore and promote the Valley’s desert mountain parks.

Cactomaniac benefits:

  • Exclusive event invitations
  • Cactomania giveaways and special offers
  • Monthly newsletter
  • The opportunity to help preserve the cactus in the Sonoran Desert and throughout the world

The History of Cactomaniacs 

Charles Mieg, a local developer and Garden member,  was so interested in cacti and other desert plants that his wife Lillian dubbed him a “Cactomaniac”. In 1950, Mieg founded a social group called the Cactomaniacs to encourage the use of desert plants in landscaping and to boost the hobby of cactus collecting. The Cactomaniacs met monthly and went on field trips to study plants as well as volunteered at the Garden. Mieg continued to lead this group for more than 20 years.
