This plant is a shrub producing a branching stem usually about one to two meters tall, but known to exceed 4 meters at times. The leaves are roughly lance-shaped and are alternately arranged, sometimes more densely toward the ends of branches. They are up to 10 or 15 centimeters long. The inflorescence is often a wide array of several flower heads, but they may also be clustered in the leaf axils or branch tips. The head contains a few yellow ray florets, which are pistillate, and up to 25 or more yellow disc florets, which are bisexual. The fruit is a rough-textured, pyramidal or prism-shaped cypsela up to a centimeter long including its pappus of many barbed white bristles.[4]
This plant is abundant in parts of its range, particularly in Mexico, sometimes becoming weedy.[4] It flowers year-round, especially in spring,[4] and it may be in full flower at the end of the dry season.[3] It is admired for its yellow flower heads and is cultivated as an ornamental plant.[3][4]
