Marking the end of summer with its sprays of bright yellow flowers, Fireworks Rough-Stemmed Goldenrod is a clump-forming perennial that provides a bold splash of color in the late season garden. This eye-catching beauty features arching flower panicles that resemble fireworks cascading off the plant, and are a great source of nectar and pollen.  The fine-textured leaves emerge burgundy in spring and change to dark green in summer. The caterpillars of many moths feed on the foliage.
