Grevillea sphacelata, commonly known as the Grey Spider Flower, is an evergreen shrub native to heathlands and dry sclerophyll forests of eastern New South Wales, Australia, particularly within the Sydney Basin and on the Woronora Plateau. It exhibits a variable habit, typically growing to a height of 1.3 to 8.2 feet with a similar spread. The shrub features silky-hairy branchlets and foliage that ranges from narrowly linear to oblong leaves. From July to January, it produces distinctive inflorescences composed of hairy, pale brown and pink flowers that are especially attractive to nectar-feeding birds and insects.

The Grey Spider Flower is valued for its ornamental appeal, including its unique flowers and adaptability to a range of soil types, from sandy to clay-loam soils. It is drought-tolerant once established, making it suitable for water-wise gardens. In cultivation, it is used for border planting, as a feature shrub, and for attracting wildlife. It prefers a position in full sun to part shade and requires well-drained soil. While generally low-maintenance, it can be susceptible to root rot in poorly drained conditions and may be affected by foliar fungal diseases in humid climates. Pruning after flowering can promote denser growth and enhance its appearance.CC BY-SA 4.0
