Banksia integrifolia – Coast Banksia is a tough, fast-growing Australian native tree ideal for coastal and inland landscapes alike.

These striking yellow blooms attract birds and pollinators, adding both beauty and ecological value to the garden.

Well-suited to windy, salt-exposed areas, Banksia integrifolia – Coast Banksia handles a wide range of soils, from sandy to loamy, and performs well with minimal maintenance once established. Its upright, irregular form works as a feature tree, windbreak, or habitat planting, offering year-round foliage and seasonal interest in low-water designs.
