T. macrogonus
This is one of my Trichocereus Macrogona. It’s fast growing, and pretty healthy. If you look at pictures of Trichocereus, the Macrogona can look very similar to Trichocereus pachanoi, and I believe it has now in fact been re-classified as Echinopsis macrogona. It contains various psychoactive alkaloids, but of course it’s such a beautiful cactus that I would never cultivate it for anything except it’s looks.

As soon as you give up the drink, something else pops up. I’ll take ten! Hotboy
I can see why they call it Macrogonads.
