Holly-leaf banksia is a primitive banksia with close links to dryandra. It grows to around 10 m and is found on the coastal plain. Unlike other banksias which have cylindrical flower spikes, flowers are arranged in a dome, and occur throughout the year. Initially white, they turn pink and then red after pollination.
