Senecio elegans is a species of flowering plant in the aster family. It is an erect or ascending, annual herb, 10-60 cm tall . The leaves have blades up to about 8 centimeters long which are deeply cut or divided into several toothed lobes. The herbage is somewhat hairy and glandular, sticky to the touch. The inflorescence bears flower heads lined with black-tipped phyllaries (leaf like plant part located just below a flower). They contain many yellowish disc florets at the center. Each has usually 13 ray florets 1 to 1.5 centimeters long which are usually purple, purplish pink or a pale white.
It is native to southern Africa and it can now be found growing wild in parts of New Zealand, Australia, Lord Howe Island, the Azores, and on the Central Coast of California.
Senecio elegans is regarded as an environmental weed as this garden escape is primarily a weed of coastal environs, particularly sand dunes, where it is spreads rapidly, displacing the indigenous vegetation.
