Banksia spinulosa var. collina, commonly known as Hairpin Banksia, is an evergreen shrub native to Eastern Australia, specifically to sandy and rocky soils in open forests, heathlands, and coastal scrublands. It typically grows to a height of 3-7 feet (0.9-2.1 meters) and a width of 3-6 feet (0.9-1.8 meters). This variety of Banksia has narrow leaves and is noted for its striking cylindrical flower spikes, which display a combination of yellow, orange, and brown hues. The flowers are particularly showy from late summer to winter, attracting a variety of pollinators, including birds and bees.

Hairpin Banksia is valued for its unique and colorful inflorescences, which make it a standout feature in gardens. It is often used in native plant gardens, as a feature shrub in mixed borders, or for natural landscaping. The plant is drought-tolerant once established, making it suitable for xeriscaping. It requires well-drained soils, preferably acidic to neutral, and thrives in full sun to part shade. While it is slow-growing and may take several years to flower, it is long-lived and can be pruned heavily to maintain shape and encourage denser growth. It is frost-tolerant, surviving temperatures down to at least −8 °C (18 °F). However, it can be susceptible to root rot in poorly drained soils and may attract Banksia borers, which tunnel into the stems.CC BY-SA 4.0
