Our Board meets monthly to discuss CACSS business; all members are welcome to attend Board meetings.

Presenter: Steve McMahon

I have a BS and MS in Plant Protection from the U of A. I have worked in the agrichemical industry and spent many years off and on working with my father in the commercial landscape and maintenance business. I have been with the DBG for 17 years first as a certified arborist, and then as Manager of the Cactaceae here. Our collection of cacti is one of the largest in the world. I have participated in three workshops in Mexico covering desert landscaping with water-efficient plants, and have traveled in Peru and Baja California, Mexico.I have been a member of the CACSS for over 20 years and served twice as president and as show chairman. In addition to collecting Ferocactus, I like Ariocarpus, Turbinicarpus, and Chilean genera. I also have many Euphorbia and Mesemb species, as well as Asclepiads and other caudiciform species.

I have converted my yard to all arid-adapted trees and shrubs, accompanied by cacti and succulents. As a result, I have diverse numbers of wildlife that live in or visit my yard, including even native bees that pollinate the various plants. I also have 5 box turtles indigenous to southeastern Arizona, which I took off someone else’s hands, and they have a good life among all the plants in the back yard.


This is an introduction to the genus Ferocactus, covering identifying characteristics, distribution of the species, and basic classification. Many of the species are shown, some with habitat photos. There are some landscaping and design tips, and information on culture. Short lists of nurseries and references are provided at the end.
