Banksia grandis

Banksia grandis, commonly known as Bull Banksia, Giant Banksia or Mangite, is a common and distinctive tree in South West Western Australia.

Bull Banksia usually grows as a tree between 5 and 10 metres high, but may attain heights of up to 15 metres. It is also found in the form of a stunted, spreading shrub, near the south coast and whenever it occurs among granite rocks. Its trunks are short, stout and often crooked, with the rough grey bark characteristic of Banksia. The leaves are very distinctive; they are very large, being up to 45 cm long and 11 centimetres wide, and consist of a series of triangular lobes that go right back to the prominent midrib. Shiny dark green on top, they have a soft white tomentum underneath. New growth is a paler lime green and very attractive. Flowering is in Summer. The large cylindrical flower spikes, which can reach up to 35cm high, are yellow, with a cream style. The "cones" shed their old flower parts early, so do not have the hairy appearance of the "cones" of many other Banksia species. Old cones are often varnished or cut and the typical banksia species used in decorative woodwork.

Bull Banksia is common throughout south west Western Australia, occurring from Jurien (30°17′S) in the north, south to Cape Leeuwin (34°22′S) and east to Bremer Bay (34°23′S 119°22′S E). It has been found inland as far as Badgedup and Dongolocking Nature Reserve. It is very common on the lateritic soils of the Darling Range, where it forms an understory in Jarrah and Marri forests. It will grow on nearly all soils of the coastal sandplain, but is somewhat less common there.

Banksia grandis is a member of Banksia ser. Grandes, a series containing only B. grandis and the closely related species B. solandri. No subspecific taxa are recognised, as it shows little variation except that it grows as a spreading shrub near the south coast. A seed from the south coast raised in Kings Park has retained its spreading habit.


Bull Banksia is very sensitive to dieback and is difficult to grow in regions of summer humidity. It requires a well drained sandy soil.

Cultural context The cone shaped flowers were called mangyt by some and pulgarla by other Indigenous groups of the region that it occurs. The flowers were steeped in water or sucked to obtain nectar
