A deciduous, perennial, shrub growing 12 to 90. The trunk has small gray brown cracks and bark that is fibrous and somewhat shreddy. The yellow green, umbrella shaped, flower blooms June to September and the fruit is an achene. Grows best on medium to coarse-textured and somewhat basic, but may range from moderately acidic to strongly alkaline, and somewhat salt tolerant. Commonly grows on dry, sandy, gravelly or heavy clay. The native prefers full sun and open plains, valley, and mountains. Reproduces from seeds and root sprouts and quickly reestablishes. Common throughout the western United States.
