Senecio erubescens is an erect, perennial herb with densely leafy, hairy, flowering stems mostly hanging sideways becoming erect. The leaves are sticky and are usually all pointing to the same side of the stem. They are lance shaped, stalkless and coarsely toothed margins. The flowers borne between Spring and Summer are bell-shaped flower heads consisting of mauve to deep purple or white to yellow florets.
Senecio erubescens is usually found in the grassland often in moist places.
