when flowering, the tips of stem branches are occupied by sessile inflorescences of 5 or 6 flowers. the knobby, waxy yellow flower buds open into golden yellow flower heads, each of which has one or two disc florets between in diameter, and one or two ray florets between in diameter. the mature plants produce many achene, although most seeds fall within a few metres of the parent plant. this is because the plant grows a very small pappus, which makes wind-borne seed distribution very inefficient.
