The Banksia Vincentia is Australia’s rarest banksia. There are only 5 plants in the wild, found in a secret location on the south coast. But the Wollongong Botanic Gardens is playing a crucial role in bringing the Banksia Vincentia back from the brink. Office of the Environment and Heritage Threatened Species Officer Dr David Bain is carefully tending the 5 plants in the wild, as well as overseeing a three-step insurance plan which includes establishing seed banks and propagating populations in Wollongong and as far afield as the Royal Botanic Gardens in Kew in England. Dr. Bain hopes that eventually new populations can be established in the wild. ABC Open producer Sean O’Brien caught up with Dr. David Bain and Living Collections Curator James Beattie in the hothouse at the Wollongong Botanic Gardens.
