This species is variable in size and form as well as leaf shape. It is confined to the coastal heathland along our coast where it is generally a relatively open, low-growing shrub.
Leaves are dark green above and pale silvery beneath. The margins can be either entire or irregularly toothed. The apex is often truncate and lightly pointed at the apex.
Large flowers in the form of a circular brush can be seen most of the year. Flowers vary from greenish to yellow with floral parts turning brown as the cone starts to mature, eventually becoming woody.
Seeds are held within woody follicles and are released annually as they mature in early autumn.
The heathland form of this species has the ability to sucker as well as re-shoot from the base following fire.
A number of Honeyeaters including the Eastern Spinebill feed on the nectar of Silver Banksia.

Indigenous uses as provided by the Wathaurung Aboriginal Corporation: Another important plant. The flowers are harvested for their nectar, making a bush cordial. The wood is used in making fire and an edible grub can be found in rotten trees.
