Encelia farinosa (commonly known as brittlebush, brittlebrush, or incienso), is a common desert shrub of the southwestern United States and northern Mexico. It has a variety of historical uses.

 

Brittlebush flower, in Sabino Canyon, Tucson, Arizona

Brittlebush grows up to 30 to 150 centimetres (12 to 59 inches) tall, with fragrant leaves 3–10 cm (1+1⁄4–4 in) long, ovate to deltoid, and silvery tomentose.[2] Arranged in loose panicles above the leafy stems, the capitula are 3–3.5 cm (1+1⁄4–1+1⁄2 in) in diameter. Each has 8–18 orange-yellow ray florets, 6–15 millimetres (1⁄4–9⁄16 in) in length, and yellow or purple-brown disc florets. The fruit measures 3–6 mm (1⁄8–1⁄4 in) and no pappus is visible. During dry seasons the plant goes drought deciduous, shedding all of its foliage, relying on the water stored in its thick stems.

Encelia californica is similar, but has only one flower head per stalk.

The leaves contain 3-Acetyl-6-methoxybenzaldehyde.
