Name derivation:
Brachyloma from the Greek 'brachys' meaning short and 'loma' meaning a fringe or edge; alluding to the hairs or scales in the throat of the corolla tube. Ericoides from Greek meaning heath-like; possibly referring to the resemblance to plants in the genus Erica.. Bicolor from the Latin 'bis' meaning twice and 'color' meaning colour; referring to the distinctive contrasting pale green corolla tube and orange lobes of the flower.
Distribution:
Endemic to South Australia and found only on Kangaroo Island, growing in mallee woodland on sandy soil or on limestone.
Status:
Native. Common in South Australia.

Flowers, solitary, axillary, bell-shaped with pale green sepals and corolla tube and bright orange corolla lobes. This subspecies is easily distinguishable from the mainland subspecies by the uniformly pink flowers in B. ericoides ssp. ericoides. Flowering between August and October.

Seed cleaning:
Place the fruits in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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 high, at 100%.
Seed germination:
This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
