While "cactus" in the name suggests a succulent plant with spines, the Russian cactus is not a true cactus (family Cactaceae). It is a herbaceous perennial in the aster family (Asteraceae). The name likely originates from its prickly, bushy appearance which superficially resembles some cacti. Its primary meaning is as the specific invasive plant described.
