Echinocereus rigidissimus subs. rubispinus (Cactus)

Also called "Rainbow cactus", because with the prolonged exposure to the direct sun, it takes on shades, ranging from pink to red and purple. E. rigidissimus subs. rubrispinus is of a columnar shape and has combed red-white spines. In spring, at the apex of the plant, large and beautiful bright magenta flowers bloom. It is a delicate cactus, because it is sensitive to rotting and for this reason it is not very easy to grow.
