'''''Banksia grandis''''', commonly known as '''Bull Banksia''', '''Giant Banksia''' or '''Mangite''', is a common and distinctive tree in [[South West (Western Australia)|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 35 cm high, are yellow, with a cream [[carpel|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.
==Cultivation==
Bull Banksia is very sensitive to [[Phytophthora cinnamomi|dieback]] and is difficult to grow in regions of summer humidity. It requires a well drained sandy soil. Seeds do not require any treatment, and take 22 to 42 days to [[germinate]].<ref name="Sweedman 2006">{{cite book | author = Sweedman, Luke; ''et al.'' | year = 2006 | title = Australian seeds: a guide to their collection, identification and biology | publisher = CSIRO Publishing | isbn = 0643092986 | page = 203}}</ref>
