On a job I did in the AZ desert, we were told that locally these were also called Compass Cactus. As the grow, the slowly, bow pointing their center, their "cowlick" as my barber would call it, to the south. Great plants, nice treatment, well done sir!
They are indeed a beautiful stunning plant that I would not want to have to deal with. Thanks for the comment. These were rather large at more than twelve inches across.
