Pincushion coneflower was first formally described in 1830 by Robert Brown who gave it the name "Petrophile dubia" in the "Supplementum" to his "Prodromus Florae Novae Hollandiae et Insulae Van Diemen" from specimens collected in 1827 near the Swan River , by Charles Fraser. In 1917 George Claridge Druce changed the name to "Isopogon dubius" in " The Botanical Exchange Club and Society of the British Isles Report for 1916". Distribution and habitat. "Isopogon dubius" grows in woodland and heath, mainly on the Darling Range from near Wongan Hills to Narrogin in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain in the south-west of Western Australia. Conservation status. This isopogon is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. Use in horticulture. "Isopogon dubius" was first cultivated in Europe in the  1800s. It prefers dry summers and excellent drainage and will tolerate moderate frosts. Full sun is required for the best flower display, although the plant can be grown in partial shade.
