-'''''Banksia integrifolia''''', commonly known as '''Coast Banksia''', is a [[species]] of [[tree]] that grows along the east coast of [[Australia]]. One of the most widely distributed ''[[Banksia]]'' species, it occurs between [[Victoria (Australia)|Victoria]] and [[Central Queensland]] in a broad range of [[habitat (ecology)|habitats]], from coastal [[dune]]s to [[mountain]]s. It is highly variable in form, but is most often encountered as a tree up to 25 metres (82&nbsp;ft) in height. Its [[leaf|leaves]] have dark green upper surfaces and white undersides, a contrast that can be striking on windy days.

Its hardiness has prompted research into its suitability for use as a [[rootstock]] in the [[floriculture|cut flower trade]], but has also caused concerns about its potential to become a [[weed]] outside its natural habitat.
