I don’t know what type of cactus this is but if you know please let me know. This cactus was one of many in the private garden of an RV park in Congress, Arizona. It shared space with Methuselah the oldest known cactus in Arizona. More about that old boy in this post.
(Decided to post some things I had in queue that I had forgotten about in the pile of other photos and posts. It’s going to be this and that for a few days until I get another theme going)
