The few species that have white flowers are called silverrod. The goldenrods were, at one time, incorrectly considered a chief cause of hay fever, probably because they bloom in late summer and autumn, at the same time as the less conspicuous ragweeds. Goldenrods attracted short-lived commercial attention when Thomas Edison found that certain species contain latex. Some species (sometimes called dyer's-weed) have yielded a dye, and the leaves of many species have long been used for medicinal preparations and teas, whence the botanical name [Lat. solidare=to make whole]. The goldenrod adds beauty to fields, roadsides, and salt marshes in so many parts of the United States that it has been chosen as the state flower of Alabama, Kentucky, and Nebraska and has even been suggested for the national flower. Goldenrod is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

(Solidago), a genus of perennial grasses of the family Compositae. They have small racemes with yellow flowers that are usually clustered in a common paniculate inflorescence. The fruit is an achene with a pappus. There are about 100 species, primarily in America but also in Eurasia. In the USSR there are about 16 wild-growing species and five to six introduced species that now grow wild. The best-known species is Solidago virgaurea, or goldenrod, which grows in the European USSR, the Caucasus, and Western Siberia. It grows in shrubs, felled forests, on the edges of forests, and in meadows. It is poisonous. Some American species contain caoutchouc. Canadian and hybrid goldenrod are cultivated as ornamentals.
