Senecio includes over 1000 species from all over the world. A large number of these species are common perennial or annual weeds, but some are succulent and caudiciforms from tropical and subtropical areas. A number of succulent relatives have now been moved to the genus Kleinia. The genus Curio contains over 20 species, all of them formerly belonging to the genus Senecio.
