Ericameria pinifolia, commonly known as Pinebush, is an evergreen shrub native to the chaparral and coastal sage scrub of southern California and northern Baja California, particularly within the Peninsular and western Transverse Ranges, extending to the Colorado Desert. It can reach up to 118 inches (3 meters) in height and is characterized by its dense, hairless, green foliage with needle-like leaves that resemble those of pine trees. Pinebush produces small, showy clusters of whitish flower heads twice annually, typically in the spring and fall. Each flower head consists of 3–10 ray florets and 11–25 disc florets, which are attractive to a variety of pollinators.

Pinebush is valued for its drought tolerance and ability to thrive in dry, well-drained soils, making it a suitable choice for xeriscaping and native plant gardens in arid regions. Its adaptability to full sun and low water requirements contribute to its ease of maintenance. In cultivation, it is often used for habitat restoration, erosion control, and as an ornamental in water-wise landscaping. While it is not commonly afflicted by diseases, it can be susceptible to root rot in poorly drained soils. Pinebush is not known to be invasive outside its native range, but gardeners should always monitor regional guidelines as ecological impacts can vary by location.CC BY-SA 4.0
