The inflorescence produces one or more large sunflower-like flower heads at the top of the hairy stem. The head has narrow, hairy phyllaries at the base. It contains up to 21 yellow ray florets each up to 4.5 centimeters long and many yellow disc florets. The fruit is an achene which may be nearly 2 centimeters long including its pappus.
