Ericameria pinifolia is a species of flowering shrubs in the family Asteraceae known by the common name pinebush. This plant is native to southern California and northern Baja California.[5][6]

Ericameria pinifolia is found in scrub and chaparral from the inland Peninsular and western Transverse Ranges foothills to the Colorado Desert. It is a green, hairless shrub sometimes as much as 300 cm (10 feet) tall. It is covered in clustered needle-like leaves each 1-4 centimeters (0.4-1.6 inches) long which at first glance look like very young pine needles. The leaves are fleshier than true needles and the plant is not closely related to the pines.[7]

Atop each of the many erect branches is an inflorescence of small whitish flower heads. The plant blooms twice per year, producing single-head inflorescences in the spring and inflorescences with many smaller heads in the fall. Each head contains 3–10 ray florets and 11–25 disc florets. The fruit is an achene with a bright white, red, or tan pappus.[7]
