Petrophile biloba, Granite Petrophile, is a perennial species of shrub in the plant genus Petrophile. It is endemic to south-west Western Australia and produces pink to white flowers, typically between June and October.
It grows as a, mainly erect, shrub to over two metres in height. It has characteristic two-lobed (hence biloba) leaves with pungent tips. Many inflorescences of pink, grey, white and yellow flowers appear along the stems from early winter to mid spring (June to October).
This species was first published by Robert Brown in his 1830 Supplementum primum Prodromi florae Novae Hollandiae.
