Banksia aemula, commonly known as Wallum Banksia, is a slow-growing evergreen shrub or small tree native to the coastal heathlands and wallum woodlands of eastern Australia. It typically reaches up to 20 feet in height and can spread equally wide. Wallum Banksia is characterized by its stiff, serrated leaves and large, cylindrical, yellowish flower spikes that appear primarily in the spring. These inflorescences are highly attractive to a variety of birds and insects, especially nectar feeders, and are considered quite showy. The bark is rough and deeply fissured, adding to its textured appearance.

In cultivation, Wallum Banksia is valued for its distinctive flowers and ability to thrive in poor, sandy soils, making it suitable for coastal gardens and naturalistic plantings. It is often used as a feature plant or in mixed shrub borders. This species prefers full sun to part shade and requires well-drained soils, tolerating drought once established. While it is generally low-maintenance, it can be susceptible to root rot in poorly drained conditions and may attract Banksia borers. Wallum Banksia is not typically invasive outside its native range but should be monitored to ensure it does not become a problem.CC BY-SA 4.0
