It was discovered by Maria Hitchcock of Armidale NSW near Nambucca in 1986 during the Banksia Atlas project.
Its leaves and inflorescences are mostly twice the size of typical plants of its parent species, Banksia serrata.
It has not yet been introduced into commercial cultivation but seed has been distributed among members of the Australian Plants Society.
Specimens have been growing successfully in the Armidale district for more than 15 years and in Canberra.
The fruiting cone is covered with dead brown styles and has prominent follicles which contain one or two large seeds with black papery wings separated by a woody spacer.
