General Description:
Banksia is a large genus of about 170 species in the Protea family, having been increased in size through the transfer of species in the former genus Dryandra to Banksia (see footnote box). The genus is almost exclusively Australian, being found in all States and Territories. A single species (B.dentata) is found in islands to Australia's north as well as in tropical Australia.
Banksia laricina is a shrub to 2 metres tall. The linear leaves are green and measure 5 to 15 mm long by 0.8 mm wide. The obovoid inflorescences are seen in autumn and winter and are about 5 cm wide at flowering, occurring on short lateral branchlets. They are yellow-fawn in colour and are often held within the foliage.
The species is non-lignotuberous and fire-sensitive; plants rely solely on seed for regeneration after bushfires. The seeds are enclosed in prominent follicles, which are bright green when new, attached to a woody cone and are generally retained within the cone until burnt. The shape of the cone gives rise to the common name ‘rose-fruited banksia’ because it is reminiscent of rose petals – unlike those of any other banksia.
Although much of the species distribution is in a conservation reserve, its range is only around 35 km. Also, wild plants are harvested for their fruiting cones, further putting the plant at risk. Thus its long term survival requires long term monitoring in the wild to prevent exploitation.
B.laricina is rarely cultivated but should require a Mediterranean climate (i.e. wet winter, dry summer) and sandy soil to do well. In common with other western banksias, the species is likely to be difficult to establish in areas with humid summers.
Propagation from seed is relatively easy.

The new classification has come in for some criticism but, as the Australian Plant Census has been adopted as the authority on plant names by ANPSA, the revised classification has been accepted on the ANPSA website. The previous Dryandra names will also be mentioned where appropriate. For further information refer to our Banksia page.
