It grows as an erect shrub 0.3–1.2 metres (1–4 ft) high with crowded elliptical leaves[2] and bright yellow flower-like inflorescences.

It is endemic to a few small areas in the Stirling Range National Park, Western Australia and as a result is classified as an endangered species.

These are clusters of drooping, nectar-rich flowers with white petals surrounded by larger yellow to lime-green, petal-like bracts.

[6]Darwinia collina was first formally described in 1923 by C.A.Gardner from a specimen collected on Bluff Knoll by "Mrs Pelloe" and the description was published in Journal and Proceedings of the Royal Society of Western Australia.

[4] This darwinia grows in dense heath and thicket in shallow, siliceous soils over sandstone and shale on mountain summits.
