Meadow goldenrod is an attractive perennial wildflower.

There are approximately 125 varieties of goldenrod found in North America. However, I am fairly certain that the pictures show the species called Meadow goldenrod (Solidago canadensis)

Goldenrod is a member of the daisy family.

Goldenrod is often blamed for hay fever in humans. However, most of the time, they are if fact being affected by the pollen produced by ragweed that blooms at the same time as goldenrod. Goldenrod pollen is heavy and sticky and thus it is not blown far from the flowers.

The goldenrod plant contains rubber. Thomas Edison was able to grow the plants in a way that maximized the rubber content in each plant. The tires on the Model T given to Thomas Edison by his friend Henry Ford were made from goldenrod.
