    History and curiosities: 

    The scientific name, Cleistocactus strausii, consists of the genus name Cleistocactus, from the Greek words κλειστός, “closed”, and κάκτος, “cactus”, in reference to the closed flowers of this cactus genus, and the Latin term strausii, “of Straus”, in allusion to the German cactus lover L. Straus (1862-1934), cofounder of the German Cactus Society.

    In Barcelona, it is unusual.
