Chrysocephalum apiculatum, commonly known as common everlasting and yellow buttons, is a perennial herb that belongs to the daisy family Asteraceae. The species is native to southern Australia. It grows in sunny locations on light, well-drained soil in grassy areas. It is an important food plant for the Australian painted lady (Vanessa kershawi), a butterfly. PS: This was the only cluster of flowers I spotted on this track.
