Curio is a genus of flowering plant in the family Asteraceae. Plants in the genus are evergreen succulents with long, striated leaves and discoid flower heads lacking ray florets. The genus contains over 20 species, all of them formerly belonging to the genus Senecio. Curio herreanus is similar to the more common Senecio rowleyanus which has the same common names. The leaves are larger, less globular, more elongate (shaped like a spindle), and more glaucous. The stems are thicker, stiffer, and somewhat more erect. Young, short plants are erect but they will be pendant or scandent with time.
