Acacia lunata, commonly known as lunate-leaved acacia, is a shrub native to the sclerophyll forests and coastal scrublands of eastern Australia. It exhibits a spreading habit and typically grows between 3 to 10 feet in height. The branchlets of this acacia are smooth (glabrous) and bear phyllodes, which are modified leaf stems that are oblanceolate to narrowly elliptic in shape. During its flowering season, Acacia lunata produces spherical flower-heads with bright golden-yellow flowers that are quite showy, followed by seed pods that can reach up to 2.4 inches in length.

The lunate-leaved acacia is valued for its vibrant floral display and ability to thrive in poor soils, making it a suitable choice for gardeners looking to add a touch of color to their landscapes. It is often used in native plant gardens, as a feature shrub in mixed borders, or for erosion control on slopes due to its root system. This acacia prefers full sun to part shade, well-drained sandy soils, and is tolerant of drought once established. While it is generally low-maintenance, it can be susceptible to root rot in poorly drained conditions.CC BY-SA 4.0
