A customer sent this to me, with not much information and not the greatest picture. ;(
"In northern Arizona (Holbrook). Hoping to use it in a cemetary restoration project as low water and low maintenance plant."
Any help would be appreciated!
The customer says that it is some type of a cactus. I am not familiar with desert type plants, living in Vermont! And it's not any of the items you listed. If you look at the second picture, the "stems" do look tubular in shape, ruling out the other items.
