Extensive Definition

The goldenrod is a yellow flowering plant in the Family Asteraceae.

Description

About 100 perennial species make up the genus Solidago, most being found in the meadows and pastures, along roads, ditches and waste areas in North America. There are a handful of species from each of Mexico, South America, and Eurasia.
Goldenrods can be used for decoration and making tea. Goldenrods are, in some places, held as a sign of good luck or good fortune; but they are considered weeds by some.
Goldenrods are mostly short-day plants and bloom in late summer and early fall and some species produce abundant nectar when moisture is plentiful before bloom, and the bloom period is relatively warm and sunny. Honey from goldenrods often is dark and strong due to admixtures of other nectars. However when there is a strong honey flow, a light (often water white), spicy-tasting honey is produced. While the bees are ripening the honey there is a rank odor and taste, but finished honey is much milder.

Garden use

British gardeners adopted goldenrod long before Americans. Goldenrod only began to gain some acceptance in American gardening (other than wildflower gardening) during the 1980s. A hybrid with aster, known as x Solidaster is less unruly, with pale yellow flowers, equally suitable for dried arrangements.
Solidago canadensis was introduced as a garden plant in Central Europe, and is now common in the wild. In Germany, it is considered an invasive species that displaces native vegetation from its natural habitat.
Goldenrod is a companion plant, playing host to some beneficial insects, repelling some pests

Industrial use

Inventor Thomas Edison experimented with goldenrod to produce rubber, which it contains naturally. Edison created a fertilization and cultivation process to maximize the rubber content in each plant. His experiments produced a 12 foot tall plant that yielded as much as 12 percent rubber. The rubber produced through Edison's process was resilient and long lasting. The tires on the Model T given to him by his friend Henry Ford were made from goldenrod. Examples of the rubber can still be found in his laboratory, elastic and rot free after more than 50 years. However, even though Edison turned his research over to the U.S. government a year before his death, goldenrod rubber never went beyond the experimental stage.

Medicinal use

The variety Solidago virgaurea is a traditional kidney tonic. It has aquaretic, anti-inflammatory, antispasmodic and antiseptic action and seems to increase kidney output. This makes it useful as an agent to counter inflammation and irritation of the kidneys when bacterial infection or stones are present. Such use is in combination with other herbs that create a synergistic therapeutic effect on the urinary system. As in other areas of herbalism, blending creates a therapy greater than the effect of a single herb alone. The aquaretic action is also useful in helping to dissolve kidney stones by diluting their components and preventing them from reoccuring. See herbal medicine. Goldenrod has also been used as part of a tincture to aid in cleansing of the kidney/bladder during a healing fast, in conjunction with Potassium broth and specific juices.
In Sufjan Stevens' song, Casimir Pulaski Day, the narrator brings goldenrod to his girlfriend upon finding out that she has been diagnosed with bone cancer. Carrie Hamby's song, Solidago, tells the story of Thomas Edison's experiments with making goldenrod a domestic source of rubber during the 2nd world war.
The Sweet Goldenrod (Solidago odora) is also the state herb of Delaware as of June 24, 1996.
