4 Wollongong flowers that are at risk of extinction

Wollongong is home to a plethora of remarkable indigenous Australian plants, some of which are found nowhere else on the planet but here in our coastal town. Unfortunately, there are a number of Wollongong flowers that have become endangered due to various reasons. The Wollongong Botanic Garden has been working tirelessly in the conservation of Australia’s most threatened plant life. To bring awareness to this valuable local cause, we’d like to introduce you to four gorgeous plants we’d like to see stick around for a while:

Pomaderris walshii

The Carrington Falls Pomaderris, or pomaderris walshii, is a critically endangered flower endemic to New South Whales. So, you won’t find her anywhere else in the world. Numbers have dwindled due to an extremely low rate of fresh seedlings growing in the understory. There are only 80 of these Wollongong flowers growing naturally in and around the Budderoo National Park, but our botanic gardens have since 2015 been replanting ex-situ propagated plants to beef up the numbers.


Pomaderris adnata

Only classified as “endangered” but at no less risk is the Sublime Point Pomaderris, or pomaderris adnata. This NWS-endemic flower can grow up to two meters tall, and is mostly found on the Illawarra Escarpment. Adult plants are threatened by bush fires, but seeds can survive the flames in the soil and re-germinate. Because of this Wollongong flower’s small number, ex-situ collections and seed banking is on the top of Wollongong Botanic Garden’s conservation agenda.


Zieria baeuerlenii

Other endangered Wollongong flowers include the Bomaderry Zieria, or zieria baeuerlenii, another special flower that only grows here in our little slice of heaven. In 2017, the Botanic Garden replanted over 300 Bomaderry Zierias in the wilderness. The following year, a bushfire ripped through the thriving new population and wiped it out. Understandably, this was a crippling setback after years of careful plant rearing. Like earth-bound phoenixes, these plants showed resilience and began re-shooting from their underground root plates.


Banksia vincentia

Love rare and unique Wollongong flowers? The banksia vincentia was only discovered in 2008, and only published as a new species in 2014. It might be relatively young, but this beautiful plant is by no means thriving. As the rarest Banksia in Australia, it is listed as Critically Endangered since only four plants are still growing naturally. However, the population of Banksia Vincentia was only 14 strong originally. Research into pollination and propagation is ongoing, with ex-situ collection and seed banking safeguarding the future of this species.
