M. pilcayensis is, I guess you could say, a columnar cactus that tends to grow on the horizontal plane as opposed to the vertical. They seem to be an easy cactus to grow— I have experienced little difficulty with them. This is a plant where I have seen people become very creative with potting styles. I have seen pictures on the internet of this cactus growing inverted from the bottom of a hanging pot— in fact, I have one like this.
