Ive had this cactus for some years, it's actually the first cactus I've owned. The anthocyanins in this species are amazing. It never grows bigger or produces pups but produces flowers from early spring to late fall. It always looks like it's about to die in the summer with its firey pink hue, but often rehydrates and fully recovers over the winter months and reverts back to a dark green. I love this cactus and can't wait to collect more in this family.
