What is the common name of the flower, scientifically called Solidago, pictured below?

Solidago, commonly called goldenrod, is a genus of about 100 to 120 species of flowering plants in the aster family, Asteraceae. Most are herbaceous perennial species found in open areas such as meadows, prairies, and savannas. They are mostly native to North America, including Mexico; a few species are native to South America and Eurasia. Some American species have also been introduced into Europe and other parts of the world.

Goldenrod often is inaccurately said to cause hay fever in humans. The pollen causing this allergic reaction is produced mainly by ragweed (Ambrosia sp.), blooming at the same time as the goldenrod and pollinated by wind. Goldenrod pollen is too heavy and sticky to be blown far from the flowers, and is pollinated mainly by insects. Goldenrods are attractive sources of nectar for bees, flies, wasps, and butterflies.

Goldenrod is the state flower of Kentucky and Nebraska and has been designated the state wildflower of South Carolina.
