Goldenrod

Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus Solidago.

Several genera, such as Euthamia, were formerly included in a broader concept of the genus Solidago. Some authors treat Oligoneuron, the flat-topped goldenrods, as a separate genus than Solidago, while others consider it a section: Solidago sect. Ptarmicoidei.Goldenrods can be used as a sustainable method to enrich soil with nitrogen. With an increase of nitrogen levels, there can then be an increase of vegetative growth.Plants known as goldenrods include:
