Origin of Name

The genus name "Echinofossulocactus" is derived from three words: 'echino', meaning 'spiny' or 'hedgehog-like', 'fossula', meaning 'small ditch', and 'cactus', referring to the plant family. This name highlights the plant's spiny appearance and the grooved structure of its stem. 'Multicostatus' means 'many-ribbed', describing the numerous ribs of this cactus. The cultivar name 'inermis' implies 'spineless' or 'without spines', distinguishing this variety from its spiny counterparts.

Technical Description of Plant

Echinofossulocactus multicostatus cv inermis is characterized by its numerous ribs, which can range from 20 to over 30, giving the plant a strikingly geometrical appearance. Unlike the typical Echinofossulocactus, this cultivar is notable for its lack or minimal presence of spines, which makes it quite unique in the cactus world. The cactus has a globular to cylindrical shape, with a green to blue-green color. It produces flowers that are typically small and range in color from white to pale pink, blooming near the crown of the plant.

Origin of Plant

Echinofossulocactus multicostatus is native to Central Mexico. This particular cultivar, 'inermis', is likely the result of selective breeding to emphasize its spineless or less spiny characteristic. It is more commonly found in cultivation than in the wild, bred specifically for its unique appearance.

Conservation Status

As a cultivated variety, Echinofossulocactus multicostatus cv inermis does not have a specific conservation status. The wild species from which it derives is not listed as endangered, but like many cacti, it could be subject to habitat loss and over-collection in its natural habitat. The cultivation of this variety helps reduce pressure on wild populations.

Care Instructions

Echinofossulocactus multicostatus cv inermis should be grown in well-draining soil, preferably a cactus mix. It requires full sun to partial shade; however, in extremely hot climates, it may benefit from light shade during the hottest part of the day. Water moderately during the growing season and reduce watering in the winter to prevent root rot. This cactus is not frost-tolerant and should be protected from freezing temperatures. Fertilize with a cactus-specific fertilizer during the growing season for optimal growth.
