Found amongst granite outcrops, in winter wet areas and on dunes from the Mid West, Peel, Wheatbelt, South West, Great Southern and Goldfields-Esperance regions of Western Australia where it grows in gravelly, sandy or loamy soils over granite, limestone or ironstone.[2]

Cultivated in gardens the species is frost tolerant and able to cope in a dry position.[4]

It was first described by the botanist Robert Brown in 1810 in his work Prodromus Florae Novae Hollandiae. Synonyms for the species include Genosiris occidentalis described by Ferdinand von Mueller in 1869 in Fragmenta Phytographiae Australiae and Patersonia bicolor by George Bentham in 1873 in Flora Australiensis.[5]
