These plants have been grown from seed collected off a naturally occurring hybrid and it will be interesting to see how each seedling will develop. There is the possibility that the seedlings will continue to display hybrid characteristics, or that some seedlings will favour one parent over the other.
The Waite Agricultural Research Institute of the University of Adelaide in Adelaide, South Australia released a cultivar called Banksia ‘Waite Orange’ with the same parentage some years ago which might be still available at nurseries.
