Sulfur Flower
Sulphur flower is a native perennial plant that naturally grows in forest openings, dry meadows, and rocky slopes in Colorado.
The dark green leaves grow as a mat-like rosette. In June, thin stalks form umbrella-like clusters of tiny sulphur yellow flowers. This plant is important to native butterflies and wildlife.
