Extremely particular cactus, whose name “invicta” means invincible, referring to the extremely robust, long and wide spines with which it is equipped. It has beautiful intense green stems that are divided into many segments, which do not reach great heights, but rather tend to form mats with a very large diameter. From each areola come out the large thorns, of variable length, which take on grayish-white colors and give the plant a truly wild look, unique in its genre!
