Name derivation:
Hibbertia named after George Hibbert (1757-1837), a London merchant who maintained a private botanic garden at Chelsea. Empetrifolia means having leaves like the genus Empetrum (Crowberry). Radians from Latin meaning radiating; referring to the characteristic broad-tubercled radiating stellate hairs on leaves of the subspecies.
Endemic to South Australia and found on Kangaroo Island and the Fleurieu Peninsula, growing on shallow lateritic soil often with ironstone in woodland or mallee but also often in scrub or disturbed vegetation.
Native. Uncommon i  South Australia.

Seed collecting:
Collect mature capsules, those that are turning a pale straw colour and contain brown seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently 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:
This genus tend to have low seed viability.
Seed germination:
This species has morphophysiological dormancy and can be difficult to germinate.
