Neoporteria paucicostata

It is a solitary cactus, which tends to become columnar with growth, of a color, that varies strongly between green, greyish and purple, depending on the variety, but also on the different sun exposure. It has very pronounced and rather acute ribs, with small transverse grooves, and its charm is accentuated by long and dark spines, which tend to take on grayish colors with age. It is a very popular species especially for its abundant brightly colored inflorescences, which pleasantly contrast with the dark shades of the stem and quills.
