About Coastal Cushion Banksia
Botanically, Banksia integrifolia 'Coastal Cushion' is a spreading groundcover in the Proteaceae family, native to Australia. It reaches around 40 cm tall and 3 m wide at maturity, with evergreen foliage. Yellow flowers appear in autumn and winter.
Where to grow Coastal Cushion Banksia
Coastal Cushion Banksia suits warm-temperate, subtropical 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
Coastal Cushion Banksia does best in sandy and free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Coastal Cushion Banksia handles dry conditions well once established. As an Australian native, feed it only with a low-phosphorus native fertiliser — the Proteaceae are especially phosphorus-sensitive. For the first year, favour occasional deep watering over frequent shallow drinks so roots move into the surrounding soil.
Pruning & care
Prune Coastal Cushion Banksia after flowering to keep it compact and encourage the next flush of blooms. Overall it is low maintenance.
Using Coastal Cushion Banksia in the garden
Coastal Cushion Banksia earns its place for holding soil on banks and slopes and drawing nectar-feeding birds into the garden.
Companion planting & design
Combine Coastal Cushion Banksia with plants that share its preference for very drought tolerant and warm-temperate climate. Use an odd-numbered group where space allows, or repeat it at intervals through a longer bed. It combines naturally with other Australian natives in a habitat or water-wise garden.
