About Your New Banksia marginata - Sale

Banksia marginata – Silver Banksia is a hardy and adaptable Australian native that thrives in diverse environments, from coastal dunes to inland slopes. Typically growing up to 10 metres tall, it may stay smaller and shrub-like in harsher conditions. Its narrow green leaves reveal silvery undersides, creating soft contrast and visual texture year-round.

Striking yellow flower cones appear primarily in winter and spring, attracting birds and pollinators. Banksia marginata – Silver Banksia tolerates wind, coastal exposure, and poor soils, making it a reliable choice for feature planting, screening, or habitat restoration. It requires little maintenance beyond occasional pruning and performs best in full sun with well-drained soil.
