Name derivation:
Brachyscome from the Greek 'brachys' meaning short and 'kome' meaning hair, referring to the tuft of short bristles or hairs of the pappus. Eriogona from the Greek 'erion' meaning wool and 'gonia' meaning angle; referring to the appearance of the seed having a woolly border.

Seed collecting:
Pick heads that are maturing, drying off, with brown seeds.
Seed cleaning:
Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads with a rubber bung to dislodge the seeds. 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 viability:
From two collections, the seed viability was high, ranging from 95% to 100%.
