Banksia integrifolia, commonly known as Coastal Banksia, is an evergreen tree or large shrub native to coastal areas and coastal forests of eastern Australia, from Victoria to Central Queensland. It can grow up to 50 feet (15 meters) tall with a spread of 10-20 feet (3-6 meters), featuring a dense canopy and smooth, pale gray bark. The leaves are dark green above with white undersides, contributing to its distinctive appearance. Coastal Banksia produces cylindrical pale yellow flower spikes, known as inflorescences, which are highly attractive to nectar-feeding birds and insects, especially during its flowering season from late summer to winter. The flowers are followed by woody seed cones that can persist on the plant for years.

Coastal Banksia is valued for its adaptability to poor sandy soils, tolerance to salt spray, and low water requirements once established, making it an excellent choice for coastal plantings and gardens with similar harsh conditions. It is also used as a windbreak, for erosion control, and in habitat restoration projects. In cultivation, it prefers full sun to part shade and well-drained soils. While generally low-maintenance, it can be affected by root rot in poorly drained conditions and may require protection from frost in cooler climates. Coastal Banksia is also popular for use in cut flower arrangements due to its long-lasting and showy flower spikes.CC BY-SA 4.0
