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. Debilis from the Latin 'debilis' meaning weak, frail, small, alluding to its habit.

Seed cleaning:
Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads by hand 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 one collection, the seed viability was average, at 60%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
