The Acorn Banksia is a large shrub or tree with smooth grey bark growing to ten metres in height. The leaves are long and narrow growing to about 25 cm long and 2 cm wide with triangular lobes on the margins making a distinctive saw-toothed edge. It produces acorn-shaped spikes of orange flowers in autumn and winter. The flower buds are woolly white before they open, and open from the bottom of the spike giving the acorn-like appearance. The attractive flowers are popular as cut flowers. The fruit is a woody cone with up to sixty follicles which contain the seed.
