False sunflower is a tall, upright and clump-forming wildflower that naturally grows in open areas of the central prairie states.
It has dark green, hairy leaves with toothed edges. Large, semi-double, golden, daisy-like flowers are borne in clusters of three on erect branches. Insects are attracted to the bright flowers during the summer, and birds are attracted to the seeds in the fall.
It makes a nice, tall flower in Colorado Springs landscapes.
At the Xeriscape Demonstration Garden, false sunflower has nice yellow flowers above tidy green leaves. It is a good bloomer.
Remove old stems and leaves in fall or early spring before new growth starts. Divide every three years to maintain bloom vigor.
