One of the few Banksia that tolerate wet or poorly drained soils
Banksia robur, commonly known as Swamp Banksia, is a bold, architectural native shrub prized for its large glossy leaves and unique green flower spikes that age to bronze. Unlike most banksias, it thrives in moist to wet soils, making it a standout choice for rain gardens, low-lying areas, and landscapes where drainage is a challenge. With its lush, tropical-like appearance and strong adaptability, it delivers both structure and resilience in Australian gardens.
