About Coast Banksia
Banksia integrifolia is a fast-growing tree in the Proteaceae family, native to New South Wales, Queensland and Victoria. It reaches around 12 m tall and 6 m wide at maturity, with evergreen foliage. Yellow and cream green flowers appear in autumn and winter.
Where to grow Coast Banksia
Coast Banksia suits subtropical, warm-temperate and cool-temperate climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds and is a genuinely water-wise choice.
Soil & planting
Coast Banksia does best in sandy, free-draining and poor soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Coast Banksia performs well with relatively little water once established. As an Australian native, feed it only with a low-phosphorus native fertiliser — the Proteaceae are especially phosphorus-sensitive. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Coast Banksia after flowering to keep it compact and encourage the next flush of blooms. Its ongoing care level is low maintenance.
Using Coast Banksia in the garden
Coast Banksia earns its place for a windbreak, a shade tree, drawing nectar-feeding birds into the garden and a feature or specimen planting.
Companion planting & design
Build the planting around neighbours suited to the same happy on low water and subtropical climate as Coast Banksia. Repeating the foliage or flower colour nearby will make the composition feel deliberate. It combines naturally with other Australian natives in a habitat or water-wise garden.
Good to know
It is regarded as non-toxic and pet-safe.
