About Coronidium rupicola (DC.) Paul G.Wilson
Coronidium rupicola is a small, erect, shrubby perennial plant that grows from a single stem. It produces terminal yellow button-shaped flower heads, which are around 2 cm (0.79 in) in diameter. Unlike other species in the genus Coronidium, this plant does not have large, conspicuous bracts; instead, it has a ring of smaller, narrow, light-coloured bracts. Its florets are densely packed, and the flower centre is greenish. Flower buds are thickly covered in long, whitish hairs, and new stem growth is silvery and woolly. The leaves are narrow and lanceolate, reaching 5 cm (2.0 in) in length. They are pale green, with a dense woolly texture on the underside and a smooth texture on the upper surface. Leaf margins are rolled under and wavy. This species flowers year-round, and its fruit is a cypsela. Coronidium rupicola, commonly called yellow button, is endemic to Queensland. It grows in rocky coastlines, road verges, woodland, and exposed ridges.
