- Broadleaf evergreen, but a drought-deciduous shrub, about 1-4 ft (0.3-1.2 m) tall, aromatic, highly branched and branches spine tipped, ashy gray, turn black with age. Leaves simple, in opposite clusters, linear-oblanceolate, 1-2 cm long, margins smooth. Flowers single, lack petals but have 4 yellow sepals, each about 8 mm, often reddish outside, 30-40 stamens. Fruit is a small, 3-4 mm, crescent shaped, brown achene.
- Sun, dry and well-drained soils.
- Hardy to USDA Zone 5? It grows in the transition zone between warm and cold deserts of southern California, southern Nevada, southern Utah, northern Arizona, and southwestern Colorado; found at elevations of 2,500-6,500 ft (760-1,980 m). Sometimes forms nearly pure stands over large areas.
- Blackbrush: "The dark gray bark makes this intricately branched shrub appear black from a distance, creating a rather somber landscape" (Bowers, 1993).
- ramosissima: much branched.
