Name derivation:
Ptilotus from the Greek 'ptilotos' meaning feathered or winged; referring to the hairy flowers. Gaudichaudii named after Charles Gaudichaud-Beaupre (1789-1854), a French botanist who sailed on Freycinet expedition (1817-20) to Australia and named a few Australian genus.

Yellow-brown globular or cylindrical head containing numerous long papery and hairy fruits, each containing one seed.
Seed type:
Orange-brown reniform seed.
Embryo type:
Peripheral.
Seed collecting:
Be very careful when collecting this species as the fruits contain fine hairs that may cause an allergic reaction for some people. Collect the fruit heads when dried to a pale straw colour. Each fruit should come off the head easily when fingers are rubbed up the stem. Collect more fruits than required as not all fruits will have a viable seed.
Seed cleaning:
Be very careful when cleaning this species as the fruits contain fine hairs that may cause an allergic reaction for some people. To clean, rub the fruit heads gently to dislodge the seed at the base of each fruit. Use a sieve to separate the 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.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
