It has long tubercles (up to 13-14 centimeters) of a greyish-green color and with a triangular section, similar to Agave leaves, the tips of which are cut to make space for areoles with a gray down and flexible spines, which are even more than 20 centimeters long.
During the warm period, large and very fragrant funnel-shaped yellow flowers bloom, which can reach dimensions of 10 centimeters!

- It is preferable to keep it at mild temperatures and never below 10 °C, for this reason it is recommended to shelter it during the winter period.
