Senecio barbertonicus, the Barberton groundsel
or succulent bush senecio, is an evergreen succulent shrub of the family Asteraceae and genus Senecio, native to Southern Africa, named after one of its native localities Barberton and is now also being cultivated elsewhere for its drought resistance, clusters of sweetly scented, golden-yellow, tufted flower heads in winter and attractiveness to butterflies, the painted lady butterfly (Vanessa cardui) in particular.
