This long-lived herbaceous shrub is native across the western U.S., and into Canada and Mexico. It reseeds prolifically, and establishes quickly on disturbed soils. It has lime green, threadlike leaves and resinous green stems. The plant is covered with yellow, flattop flower clusters in the early fall. Although it will establish and thrive under almost any conditions, full sun exposures and minimal irrigation are recommended. Dry plants are very flammable.
