This is labeled as a haageocereus pseudomelanostele. I’ve had it for a few years. It used to have another on each side of this one, but they recently became diseased and died, but I was able to save this one. Within the past year or so, I was re-potting it and the top broke off. As time went on, the 2 “sprouts?” on top started growing. Are these technically pups? If so, does anyone know how to properly propagate them?
