I got this clumping cactus from walmart and it's being labeled as an "Indoor" cactus. It looks like it starts out very small and clumpy but will get tall (this one is about 12" tall). Does anyone know what's the name of this one?
I saw those at my Walmart too. I am curious to see what it is. Hope someone knows.
I believe that is Cereus hildmannianus f. monstruosus cv. Fairy Castle.
Thank you so much valkyrie46225 and Xenomorf. You guys are great help!!! :)
