The name Escobaria honors two brothers Romolo and Numa Pompilio Escobar - the two naturalists, who, at the beginning of the twentieth century, discovered and classified many species, belonging to this genus. These are small globular cacti, which do not grow excessively in size, but often tend to form bushes, equipped with tubercles, from which light-colored spines of various shapes emerge. In warm periods their elegance is accentuated by funnel-shaped inflorescences, which are strongly decorative. They are very appreciated and highly sought after by green collectors, because of their size, which makes them miniature jewels of elegance, as well as for their extreme resistance to dry cold: some species, especially those unusually compared to other cacti, which come from northern areas such as Canada, survive without problems even at temperatures of -20°C!
