Inflorescence  numerous in dense subglobular heads, brown, to 12 mm long and 4 mm wide, compressed, with 8-12-flowers, usually deciduous as a whole when ripe. Flowering between November and January.

Seed collecting:
Collect fruits by picking off the mature heads, those turning a brown colour and come-off easily.
Seed cleaning:
Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
