Goldenrod

For other uses, see Goldenrod (disambiguation).

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

Solidago nemoralis, old field goldenrod

Euthamia graminifolia, grass-leaved goldenrod

A field of goldenrod in the Midwestern United States.

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,^[1] while others consider it a section: Solidago sect. Ptarmicoidei.^[2]

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.^[3]

• Bigelowia spp., rayless goldenrods, 2 species native to the Southeastern United States^[4][1]
