Grevillea crithmifolia, commonly known as Spider Flower, is an evergreen shrub native to coastal heathlands and open eucalyptus woodlands in Western Australia. It typically grows to a height of 0.6–2.5 m (2 ft 0 in – 8 ft 2 in) and is characterized by its dense growth habit with linear leaves. The branchlets are covered with shaggy hairs, adding to its unique texture. Spider Flower produces clusters of pale pink to creamy-white flowers that are quite showy, attracting nectar-feeding birds and insects. Flowering occurs from June to September, and the fruit is an elliptic to oval follicle 12–15 mm (0.47–0.59 in) long.

Grevillea crithmifolia is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for water-wise gardens and xeriscaping. Its striking flowers and dense foliage make it an excellent choice for use as a screen or hedge in cultivation. It is also used in coastal plantings due to its tolerance of salt spray. This shrub prefers full sun exposure and requires soils with good drainage. While it generally requires low amounts of water once established, it may benefit from occasional watering during prolonged dry periods. It is relatively low-maintenance, but gardeners should be aware of potential issues with root rot if planted in poorly drained soils.CC BY-SA 4.0
