An outstanding oddity and conversation piece. This species of cactus formerly known as C. peruvianus has forest green tall, non-branching stems that proliferate with many offsets from the base. The effect is like a castle with many ‘spires’. The tan spines are small but do not readily come off. Keeps its proliferating habit throughout its life, getting fuller with each step up in container size. A great starter plant, low maintenance but very rewarding.
