It is a small shrub with yellow or red pendulous flowers and papery leaves.

Diplolaena graniticola is a shrub to 1.5 m (4 ft 11 in) high with smooth branchlets that are covered in scales or star-shaped hairs.

The corolla is yellow or red with five overlapping petals, 5.5–6 mm (0.22–0.24 in) long and hairy on the edges.

[2][3] Diplolaena graniticola was first formally described in 1998 by Paul G. Wilson and the description was published in the journal Nuytsia.

[5] This diplolaena mostly grows in granite outcrops east of Perth in the Darling Range from Mount Observation and south to Wagin and Collie.
