Sprengelia monticola is an open or low-lying, glabrous shrub that typically grows to a height of 20–50 cm (7.9–19.7 in).

[2] This species was first formally described in 1839 by Augustin Pyramus de Candolle in Prodromus Systematis Naturalis Regni Vegetabilis and was given the name Ponceletia monticola from an unpublished description by Allan Cunningham.

[3][4] In 1917, George Claridge Druce changed the name to Sprengelia monticola in the supplement to The Botanical Exchange Club and Society of the British Isles Report for 1916.

[6] Rock sprengelia grows on wet sandstone rocks and cliff ledges in the Blue Mountains of eastern New South Wales, often with cliff ledge vegetation such as king fern (Todea barbara) and Dracophyllum secundum.
