Habitat
Usually grows in rocky areas in open forest but also found in monsoon forest and rain forest (Zich et al. 2020). Mainly in exposed rocky crevices and ledges (Conn 1992: 626). "Usually in dry, often rocky forest and woodlands in Gippsland between the New South Wales border and near Licola, with outlying and very localised occurrences on basalt cliffs of the Leigh and Moorabool Rivers near Geelong" (Walsh 2018).

Mature width

Native range
Eastern Australia from Cape York Peninsula, Queensland, through eastern New South Wales to north-eastern Victoria (and with outlying and very localised occurrences further west near Geelong). Collected on Lord Howe Island by Maiden (1898), as Plectranthus parviflorus, but not collected since, presumably therefore extinct on the island.
