As with Banksia ericifolia subsp. ericifolia, this is a compact shrub up to 5 m high, but the leaves are more crowded, the individual flowers are larger and the flower colour is often darker.
It is an adaptable species and makes a good windbreak or screen plant and can withstand a considerable amount of salt spray. The dense foliage and nectar-rich flowers make it an excellent choice for attracting both insectivorous and honey-eating birds. It prefers well-drained soil and would make a useful and decorative addition to a large garden.
