Darwinia terricola, commonly known as the Blackwood bell,[2] is a species of flowering plant in the myrtle family Myrtaceae and is endemic to a small area in the south-west of Western Australia.

The flowers are surrounded by several rows of leaf-like bracts which are green at first, but which turn reddish-green and increase in size to 13–20 millimetres (0.5–0.8 in) long and 2 millimetres (0.08 in) wide as the flowers develop.

[2] Darwinia terricola was first formally described in 2012 by Greg Keighery from a specimen collected in the Blackwood State Forest between Margaret River and Nannup.

[3] The specific epithet (terricola) is derived from the Latin word terra meaning "earth", "ground" or "soil"[4]: 291  and the suffix -cola meaning "inhabitant",[4]: 217  referring to the prostrate habit of this species and the manner in which the flowers lie on the ground.

[2][5] Darwinia terricola is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife.
