Grevillea acanthifolia, commonly known as Acanthus-Leaved Grevillea, is an evergreen shrub native to the dry sclerophyll forests and coastal scrublands of New South Wales, Australia. This species is characterized by its stiff, prickly, deeply divided leaves that resemble those of the Acanthus plant. It typically grows to a height of 0.5 m (2 ft) but can reach up to 3 m (10 ft) tall with a spread of 4 m (10 ft). The Grevillea acanthifolia produces distinctive pink to purple "toothbrush" flowers, which are most prolific from October to February, although it can flower sporadically throughout the year. The flowers are followed by hairy follicles with reddish markings that contain the seeds.

The Acanthus-Leaved Grevillea is appreciated for its unique foliage and vibrant flowers, which attract nectar-feeding birds and insects, enhancing biodiversity in gardens. It is suitable for use as a feature shrub in rockeries, native plant gardens, and as a part of mixed borders. This shrub is known for its frost tolerance and ability to thrive in nutrient-poor soils, making it a low-maintenance choice for gardeners. It requires well-drained soils and can tolerate drought once established, making it suitable for xeriscaping. However, it may be unreliable at lower altitudes and in more humid climates.CC BY-SA 4.0
