Flowering-head  terminal on a long stalk with 8-20 yellow tubular flowers in the umbel. Flowering between April and September.

Seeds are recalcitrant, that is they do not survive drying and freezing and can not be stored long term  for ex-situ conservation.
Seed germination:
Seeds are recalcitrant and will germinate readily.
